How to maximise the life of the Apple battery charger set (for Magic Mouse) batteries?

Lithium batteries do not like complete discharge, so do it at 10% or higher. You can leave them as long you wish in the charger, it will stop charging when full.

The battery charger it self has no limit on life time, yet again, it has to work harder if completely drained battery is to be charged.

If for some reason you have to leave the batteries on the shelf (in the box) for longer periods (months) then do it a 40% charge and keep them cool (15 Dgr. Celsius preferred).

Then when you notice the ones currently in use are at 20% start charging the replacement (from the box).


Can I retrieve my notes from my iCloud without the phone?

All your iCloud notes are accessible from iCloud.com/#notes2. If the notes you're looking for are not listed here, they are not stored in iCloud.


what is the proper bootcamp software for windows 10 on macbook pro early 2011

You should be using Boot Camp Support Software 5.1.5621. You can download the software from the given link. With later versions of macOS, the Boot Camp Assistant can be used to download the software.

You probably will need to install Windows to legacy BIOS boot. This means the drive will have to be hybrid partitioned. This is where Windows uses the MBR partition table and macOS uses the GUID partition table (GPT). Also, you should use the optical (DVD) drive to install Windows. If you have latest firmware installed, then you might be able to use a flash drive to install the latest Windows 10. Currently, with would be the October 2018 update. You can get the latest firmware by having the latest version of High Sierra installed.

You can not BIOS boot from a flash drive. If you succeed in booting the Windows installer from a flash drive, then you will have used an EFI boot method. However, even though you have EFI booted the installer, you still will need to install Windows 10 to BIOS boot. This is because the Boot Camp Support Software 5.1.5621 probably contains drivers that require Windows to BIOS boot. Instructions for properly use a flash drive to install Windows 10 can be found at the accepted answer to the question: How to install Windows 10 into a 2011 iMac without using the Boot Camp Assistant, an optical (DVD) drive or third party tools?


How can I give my sister my iPad 2 with the videos and music from my iTunes account intact?

Once she decides to sync the device once, the contents will still be removed. Your sister won't be able to back up the videos and music or sync it to her iCloud, but it should keep playing all the media for months to come. If she erases it or syncs it with a new computer - she can return it to you for a reload or just start fresh with her songs at that point.

To remove your accounts, open the Settings App:

Remove the passcode (optional but nice to for her to choose one)
iCloud - tap Delete Account and delete all the content. Optionally delete your backup of this device in Storage & Backup if you don't care to keep that backup around and free up your cloud space.
Mail, Contacts, Calendars - delete all accounts and data here
Notes, Reinders, Messages, Facetime - same as above
Safari - clear cookies and history
iTunes & App Store - Sign out by tapping the account name for Apple ID
Music - Sign out of Home Sharing by tapping the Apple ID
Videos, Game Center - same as above

Sign out of social media - Twitter, Facebook, Flickr, Vimeo

Privacy - Location Services - Turn Off - that deletes your information from Apple if you chose to share it. Optionally review the apps that have requested access to private data and turn them off / delete the app so she can choose what she shares.
Privacy - Advertising - Reset Advertising Identifier and optionally Limit Ad Tracking

She should be fine adding her Apple ID and just will want to watch for prompts that indicate if she will ever wipe your videos and music. Depending on what you choose, you might just erase all content and settings and copy the Music and Videos to a $50 hard drive or large USB drive so she can incorporate them in her iTunes library rather than have you surgically remove things. The out of box experience does guide a new user to understand what accounts and settings she can opt in and out of.


How to switch off sharing of history between iTerm2 tabs when setopt command not found

It's the history -a part of PROMPT_COMMAND in your .bashrc - that's appending to the history file every time a prompt is displayed, whatever tab you're using. A quick fix would be to remove this, so that each tab's session only writes to .bash_history when the session ends (e.g. when the tab is closed).

I like this behaviour (immediate appends to .bash_history), and I suspect you may too! A better solution may be to maintain separate histories for each session/tab - one of the answers to this question describes how to achieve that. You could retain immediate appends, but to separate files - one for each session. You would still be able to search your entire bash history with a command like grep "foo" ~/.bash_hist*. (I've not personally tried this: I use one history file for all sessions, since my normal workflow tends to be in one tab or through screen, and I archive my /bash_history periodically into a separate file, as described in this article - which is well worth reading, even if it doesn't address your issue).


How to map the 'Mission Control' key to F3 via Karabiner?

Although the proposed solution works, there are better alternatives IMO. To remap mission_control to right_command for example, you can also:

Add a rule to Karabiner-Elements such as:

{
  "type": "basic",
  "from": {
    "key_code": "mission_control",
    "modifiers": {
      "optional": [
        "any"
      ]
    }
  },
  "to": [
    {
      "key_code": "right_command"
    }
  ]
}

or

Go to System preferences -> Mission Control -> Keyboard and Mouse Shortcuts -> Mission Control and select Right Command


I figured it out. For those who have the same problem, it was Cindori's Command Center utility. Repeatable on my machines: iTunes won't quit with CC running; will quit if CC isn't running. CC has a function to control iTunes; should have remembered that.


How do I view full process paths in Activity Monitor?

One way: select the process, then View -> Sample Process. In a few seconds a window will pop up like:

"Path:" contains the fill path to the executable.


ssh into my local ubuntu virtual machine

Make sure you are using Bridged Adaptor in the VirtualBox settings. User Pinhead reported that Promiscuous Mode should be set to Allow All.

In an Ubuntu Terminal window, enter the command below to see if the proper software is installed

sudo systemctl status ssh

If not, then use the commands below to install.

sudo apt update
sudo apt install openssh-server

If you do not know the ip address assigned to the Ubuntu virtual machine, then execute the following steps.

Open the Activities overview and start typing Network.
Click on Network to open the panel.
Click on the  symbol. You should see a image similar to the image shown below.

You can use either the IPv4 or IPv6 address.

In a macOS Terminal window, enter the command

ssh <username>@<ip address>

For example, if using the username dma and either of the ip addresses from the above image, then both commands below would work.

ssh dma@192.168.0.115
ssh dma@2001:470:1f11:4a6:281d:ecf9:cd9e:76a8


On OS Catalina Delete the account you are currently logged into

The closest you can get to delete your admin with the name admin_username (even with no other user left afterwards) without logging in as a different user in the GUI is to enable root and remove your admin with the superuser:

Open Terminal.app
Enable root with dsenableroot. You have to enter your admin_username password and choose a new password for root and verify it.
Change to root: su - and enter root's password.
Enter:

rm -dR /Users/admin_username; dseditgroup -o delete -n . -u admin_username admin; dscl . delete /Users/admin_username; reboot

The password of admin_username is probably required. I ran several tests with various permutations of the command above and either dseditgroup or dscl asked for it.

Warning: This will remove all admin_username files & folders! Most files can be recovered with a data recovery tool.

Afterwards the root user will be enabled and depending on your settings it will be visible as "Other users..." on the login screen.

The command was tested in a virtual machine. The admin user had a relatively small user folder (< 5 GB). On a real machine your milleage may vary.

Reading and interpreting all related questions and comments I suspect that the MacBook Air is a shared computer with two admin accounts belonging to different parties (PvsP/PvsB) being at loggerheads in the meantime.

I would hand over the computer to a wise, reliable and neutral person, explain the dilemma and expect a Solomonic solution.


Music synced with iTunes has a very low volume on iPhone?

You might have selected "Sound Check" (which will adjust your song volumes). Look at your iTunes preferences -> Playback to see if that is the case. Turning it off might help.


Is it possible to crossfade songs on an iPhone?

I'm sorry, I don't think it is possible (yet). If you had an old iPod Nano/Classic then I might have suggested 'Rockbox' (give it a google). Send Apple a feature request about it, they never know, if enough people bombard them with requests then maybe it will become a native feature.

Sorry I can't be of more help.


Keeping emails on the server when using an iPad 2 for email

The iPad supports 2 Mail mechanisms that allow you to do this, IMAP and Exchange.

Both of these mechanisms allow the server to control the status of mail messages, whether they are read/unread etc, what folders they have been moved into.  If you use either of these mechanisms then you can expect to see basically the same content no matter what you use to view the mail on.

The key is what email service you use, as to whether it supports IMAP or Exchange, or something older like POP3 that will now allow such consistent mail states.

iCloud accounts from Apple effectively use IMAP behind the scenes.  GMail can be configured to use pretty much any mechanism, and so can also be happily used.


How can I salvage macos resource forks when copying from a non hybrid ISO 9660 Rockridge CD

If the resource forks are available under the names you're describing, here's a way to recombine them:

cp -a /source/filename /destination/filename
dd if=/source/._filename of=/destination/filename/..namedfork/rsrc

This will still not copy over the type/creator and other Finder metadata, but it will copy over the resource fork.


iPhone error "Unable to connect to network"

Whilst I have no idea what caused the problem, it was solved in this case by

Disabling security on the Wi-Fi network,
Connecting the devices to the unsecured network (which worked),
Re-enable security,
Connecting the devices to the secured network.

Somehow, this solved the problem and all devices were able to connect normally.

On our TP-LINK router, a reboot was required whenever the security settings were changed, i.e. after steps (1) and (3).

Rebooting the phone's was not required, though I think I may have turned the Wi-Fi on the phone off and on again.

Hope it helps!


How to disable certain Apps & access to PIM data on iOS

Sorry, under stock iOS there is no way to restrict apps except thru the parental controls you already mentioned.

Outside of the stock iOS however, there are multiple solutions to do this, my favourite of which is iUsers that enables multiple user accounts including guest accounts on iOS devices.


Check this. It appears that attachments can be added to local calendars only. It may also be possible with calendars synced with remote servers, if the server supports it (but that's just a speculation, I don't know if such servers exist)


Is there an easy fix for an old iPhone 5s battery?

Battery Drop of 5% in two hours is not bad

A battery drop of 5% within two hours is not bad at all. How much does it drop throughout an entire day? How long can you use it for taking a few calls, browse a little?
If it only drops heavily, when not in airplane mode, please check your battery usage: Settings -> General -> Usage -> Battery Usage

Replacement

Apple offers an about $80 (+ $7 shipping) battery replacement-program for iPhones https://www.apple.com/batteries/service-and-recycling/

Alternatively, if you - or a friend of you - like to fix things yourself you could consider a iFixit iPhone 5s Battery replacement kit, which is about $30 (without shipping)  https://www.ifixit.com/Store/iPhone/iPhone-5s-ReplacementBattery/IF124-002-2

iFixit provides very useful guides of how to fix electronic devices from Apple or other manufacturers.

Check warranty

You might want to also check your warranty status: https://selfsolve.apple.com/agreementWarrantyDynamic.do

If you have an AppleCare Protection Plan they might replace the battery for free!


Run java bundled in .app from command-line

Is there a way to permanently "Deny" an application incoming network connections (i.e. no more prompts)?

No not really, when you open a program whatever core process it calls into action are run every time. One of which will, in your case, checks on the various permissions it has to make or accept outgoing/incoming connections. The act of double clicking and opening the application (even after choosing to deny such privileges) will overwrite/trash your past decisions to DENY incoming/outgoing connections simply because you gave it permission to open (not when you ACCEPT though - in this case any previously accepting connections will not continue to ask for your permission).

Unless there is a setting within the application's "Preferences" or you change some code within the "Contents" of its bundle then it is highly likely that it will prompt you every time.

BTW these permissions requests are meant to alert and pop up every time to keep users from making "permanent decisions" (AKA turning off popup notification and permission requests). Without the popup requests, switching permissions settings back and forth would become a much more difficult task and more than likely need the help of a genius bar rep to switch them back and forth (for the not-so-savvy users at least).


Can I use the Mac OS X Install DVD that came with my Mac Mini on my Macbook?

The installation disk coming with a computer is for that computer model only, and I would not expect this to work.

If your MacBook runs 10.5 you are eligible for the 10.6 upgrade for $29.  I can highly recommend it, if nothing else, for the fixes in Time Machine.


2 Clash of Clans account on the same Game Center account

Attach your old village to a new Game Center account:

Launch Game Center on your old device, create a new free account and login; while logged in, launch the game. If you get the "Welcome back, yourusername" message at the top of the screen, your village is now attached to your Game Center account!

Load your village on the new device:

Launch Game Center on your new device, and login with the same username and password you used in the old device; while logged in, launch the game, and you will get the following message:

Tap "Okay" to load your old village on the new device.  This will delete the new, unwanted village.

Why does "Chromium Helper EH" crash when I try to launch Chromium?

It turns out that in 10.7.3, installing Chromium/Google Chrome from another account causes this bug. Simply installing it while using the account it will be used in solves the problem. Unfortunately, no other accounts can use it.


Error downloading Mountain Lion from AppStore

Muhammad Reda - I've got the exact same issue with my iMac. I contacted the Apple Store and they said because so many people are trying to download it, the download button should come back on at least some time in the next few days. Hope this helped.


Can I take the optical drive out of my MacBook Pro?

Yes, it is possible to remove the optical drive. However, it isn't that easy. You will need several specialized screwdrivers, a tool to remove the cables, and some manual dexterity. If you have experience disassembling laptops it will not be a problem.

Go to ifixit.com and find the instructions for your model.

Side note #1: this would be a good time to change the spinning drive for an SSD.

Side note #2: I don't find the price of MacBooks these days to be excessive. Have you seen the junk you get for $500?


Is it a good idea to create a "soft link" from iTunes Library to an external hard drive to release hard drive space?

It's a better idea to copy the iTunes Media folder to your external hard drive, then go to iTunes Preferences > Advanced tab and change the iTunes Media folder location to the one on your external disk.

You can also move the library file itself (in ~/Music/iTunes/ on my system), but I don't recommend doing both at the same time. There're other questions around here that go about explaining how to use a different library location.

To more-directly answer your question, I don't know of any downsides to using symlinks, but that's because I've never done it. I have done the approach I described here and it's generally better to avoid going behind an app's back if you can.


Can Apple watch warn me when my iphone is out of range

I haven't found an app that does this yet either. Your best bet would be to wait for the upgrade to watchOS 2.

This should enable developers to add more functionality to their apps, including the function you're in need of.


Restore user data, settings and apps from hard-drive copy

When you say settings what do you mean?

What current version of MAC os will you be restoring too?

Migration Assistant will allow you to restore from an external drive, if the drive has been formatted in the OS X Journaled format with the proper GUID.

If you connect to the iPhone not via wifi but via bluetooth, there is no need to do anything on the iPhone, just establish the connection using the iPad's bluetooth settings. Of course, bluetooth on the iPhone must then remain always switched on. I do this all the time, the iphons remains in the pocket ...


Run iPhone Apps on MacOs Laptop for free

You cannot run iOS applications on anything other than iOS. And you need a device capable of running iOS (iPhone or iPad).

The reason being is that iOS applications are compiled to run on the ARM-based processor. OS X (and most desktop or notebook operating systems) run on the i386 or x64 architecture.

To run a different arch-type, you'd need an emulator. And all Xcode has is a simulator.


How Do I use the Logitech G600 mouse with my Macbook pro?

Personally, I stopped using the Logitech drivers with my Logitech mouse and installed USBOverdrive instead. It's a great USB driver that gives you total control over all the buttons on your mouse.

USBOverdrive website

Any button can be linked to all sorts of system functions, keys, scripts, etc.


You can do this in Mavericks pretty easily (I just did).

Go to System Preferences -> Keyboard -> Shortcuts, select "App Shortcuts" and click the + button. You'll be asked to select the app you want to create a shortcut for (Keynote, in my case), the exact text of the menu item you want to create a new shortcut for ("Play Slideshow" in my case), and the keyboard shortcut you want to assign (Shift-F5 in my case, which is what the Logitech R400 uses for "start slideshow").


Sure you can.

You can set your preferred account as Organiser, with Share my purchases switched on, then invite & add your other account as an Adult (you could set yourself up as a child, but then you'd have to ask yourself permission ;)

From System prefs > iCloud > Manage Family...
First & last are 'me'

One caveat - you need to make sure that the two addresses aren't already associated. I had great difficulty figuring out why adding my second account wouldn't work. It turned out to be [iirc] that each was using the other as the rescue or secondary email address.

As you're setting it up initially you need two devices [or accounts on a Mac] each to be signed into its own account. It took some juggling for me to set this up on a single Mac, but between iPhone & Mac ought to be simpler.

Full setup details at Apple KB: Set up Family Sharing

I'm not sure whether doing this will enable the right to the Mac version of an iOS app. It usually wouldn't, but the iWork suite & Apple's own software in general seems a bit of a special case.


Storing files in iCloud without a copy being saved on my Mac?

iCloud Drive is specifically to sync your data between machines, roughly similar to how Dropbox etc works.

Remove a file from one machine, it's gone from the others too.

'Documents & Data' was deprecated & is removed when you first convert your iCloud (Mavericks/iOS 7) storage to iCloud Drive.

Alternative suggestion [untested]

How about - as you don't mind having one copy locally, just not two, changing your iTunes Library location to a folder inside the iCloud hierarchy?

Move your actual 'Music' folder there & just point iTunes to it


Somewhere around late 2014 is got very reliable for me. I don't know if iOS changed, OS X changed or both, but before then I continued to have the problems you describe with Mountain Lion 10.8.4 and earlier.

Of late, this has been quite solid and at worst, toggling the connection in network preferences on OS X fixes any connection issues with iOS hotspot being solid in general.

Before the fixes, the problem seems to be a timing issue.

What I've found is that if the connection light doesn't show green, I want to disconnect the device and turn off tethering on iOS. After waiting 5 seconds or so, I turn on tethering again on iOS and be sure to leave the tethering screen showing. (don't leave the settings app) I then reconnect the device and listen for it to signal that it's connected with the chirp iOS makes when connecting to a computer. If the light doesn't go green in system preferences, I toggle the Personal Hotspot off, count a few seconds and turn it on.

Occasionally, something just isn't correct on the Mac end and I switch to Wi-Fi tethering and delete the interface in System Preferences and then start over with the set up.

I wish I could say this worked reliably for me, but it seems to be fidgety and prone to errors and lock up.


How can I keep B&O Z2 consistently connected to Airplay?

I haven't been able to accomplish this without additional equipment. It seems that the networking in the Z2 is faulty. I instead connect an AirPort Express aux port to the Z2 aux port and airplay to the AirPort (after enabling airplay in the airport settings). The AirPort streams perfectly without dropping the connection and the Z2 still sounds great over aux. It'll stay connected as long as you're on the same wifi network.


My iPad mini 4 randomly turns off when i shake it!

You're holding it wrong! - Stop shaking it!

Seriously - you're experiencing problems with defective hardware. Take it to a proper repair shop and get a fixed price on fixing the issues.

You should probably prepare for the fact that buying a new iPad is cheaper than repairing the old.


How to open two ports (both TCP / UDP) using pf

You have two options here: a very simple one and second one which requires a lot of work because unlike Parallels VMware Fusion doesn't provide a NAT & port forwarding interface.

Neither requires Murus or pf.

Bridged Mode

Instead of connecting the Windows 10 VM in NAT-mode use the Bridge Mode and choose - depending on the connection of the OS X host - either the Wi-Fi or Ethernet interface. In Bridge Mode your VM acts as a separate host in your main network.

If your main network has the network address 192.168.0.0/24, the router 192.168.0.1 and your OS X host something in the range 192.168.0.2-192.168.0.254 then you have to configure the Windows VM with a static but unique IP (e.g. 192.168.0.10) in the same range. This is done in the System Preferences of the VM! All other settings (Netmask/Gateway/DNS) there are identical to the settings of the OS X host. I also recommend to set the Mac to a fixed IP (e.g. 192.168.0.2)

In the Windows 10 guest also configure the Firewall and open port 1338 and 1340 to the world.

Now connect to your Linksys X3000 router and configure port-forwarding:

Navigate to the port forwarding section.
Click the Applications & Gaming link.
Click the Single Port Forwarding button to forward ports.
Create two port forward entries. In the To IP Address box you have to enter the IP of the Windows 10 host!

Application Name    External Port   Internal Port   Protocol    To IP Address   Enabled
1338server                   1338            1338       both     192.168.0.10       yes
1340server                   1340            1340       both     192.168.0.10       yes

Save the settings

I don't have access to Linkysys router so I can't provide screenshot and can only guess how it looks like.
NAT-Mode (which in fact is a double-NAT: first your router and then the VMware NAT)

Some basic knowledge of the CLI is required here.

To get port forwarding working in VMware you have to modify several files, set up port forwarding twice - on the router and in VMware - and add a route to the NAT'ed VMware network on the router.

Modify .../vmnet8/dhcpd.conf in Terminal.app:

Open in VMware the configuration of the Windows 10 host and make a note of the MAC address of the network interface (e.g. 00:0C:29:04:D7:33)

cat the file /Library/Preferences/VMware\ Fusion/vmnet8/dhcpd.conf and check the range  (that's the dhcp-range e.g. 172.16.106.129 172.16.106.254) and other used addresses (e.g. option routers 172.16.106.2).

Edit dhcpd.conf

sudo nano /Library/Preferences/VMware\ Fusion/vmnet8/dhcpd.conf

After the line “####### VMNET DHCP Configuration. End of "DO NOT MODIFY SECTION" #######” enter the following lines with the MAC-address found earlier and an unused IP-address:

host Windows10 {
hardware ethernet 00:0C:29:04:D7:33;
fixed-address 172.16.106.56;
}

Modify .../vmnet8/nat.conf in Terminal.app to enable port-forwarding:

sudo nano /Library/Preferences/VMware\ Fusion/vmnet8/nat.conf

in the part [incomingtcp] add

1338 = 172.16.106.56:1338
1340 = 172.16.106.56:1340

in the part [incomingudp] add

1338 = 172.16.106.56:1338
1340 = 172.16.106.56:1340

Relaunch VMware Fusion
get the IP of your Mac connected to the router with ifconfig (e.g. 192.168.0.2)
Access your router
add port-forwarding like in Bridge Mode but to the IP entered in dhcpd.conf:

Application Name    External Port   Internal Port   Protocol    To IP Address   Enabled
1338server                   1338            1338       both     172.16.106.56      yes
1340server                   1340            1340       both     172.16.106.56      yes

add a static route to the 172.16.106.0/24 vmnet8 network:

Route Name: vmnet8
Destination LAN IP: 172.16.106.0
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.2 #the IP of your Mac's interface connected to the router (either Wi-Fi or Ethernet) you got by entering `ifconfig`.

Save the settings
Launch your Windows 10 VM and configure the firewall (see Bridge Mode)
Launch your "services" on port 1338 and 1340.
Done!

Make a backup of the files nat.conf and dhcpd.conf before updating VMware Fusion because they will probably be replaced.

In my answer I assume that pf isn't running or if it is enabled then with the default pf.conf. You can check whether the firewall is running or not by entering sudo pfctl -s all | grep Status. If it is enabled open Murus Lite and check the state of the firewall. If you see a yellow light in the upper right corner it's running with the default Apple rules (which don't block anything). If you get a green light you've enabled the packet filter with the default Murus pf settings and you either have to open the ports 1338 and 1340 for incoming traffic on your Mac's interface connected to the router (e.g. en0) or uninstall the (Murus) boot scripts (Firewall > Boot Scripts > Uninstall Boot Scripts ...) and stop pf (or reboot). Removing or uninstalling Murus (Light) is not required.

Without modifying the two config files of VMware you won't be able to "open" or "redirect" ports with Murus (Lite) to a guest VM because the VMware NAT behavior can't be controlled by pf.


Charging suddenly stop when I try to use the device

I would start with resetting your Mac's System management Controller (SMC) and also checking your battery status.

Reset the SMC

To reset the System management Controller on your particular MBP, follow these steps:

Shut down your computer
Keep the power cable plugged in
Press at the same time shiftoptioncontrol (on the left side of the built-in keyboard) and the power button and hold all these down for at least 10 seconds
Let go
Turn your computer back on with the power button.

After resetting the SMC, use your computer to determine if the issue still persists.

I'm also guessing you won't know the history of the battery, so it'd be good to check the status of your battery once the SMC reset is done.

Check battery status

Ensure your MacBook is connected to a power source
Go to Apple > About This Mac
Ensure you have the Overview tab selected
Click on the System Report... button
After the System Information window appears, click on the Power option (it's listed in the lefthand menu within the Hardware section)
Now on the righthand side take note of the following items:

How do I find which directories are taking up my inode count?

HFS+ does not use i-nodes. New files can be created as long as there is free disk space.

The compatibility layer that emulates the i-node behaviour always reports a percentage of used i-nodes equal to or slightly less than the percentage of used space.


Using Car Speaker As Music Player in iPhone

If your stereo does not register that it supports the A2DP profile, then it likely will also not handle A2DP communication. It is not as simple as finding an app that will "fix the problem", because the problem is likely that your Stereo does not support audio playback. The level of difference between A2DP for audio playback and HSP for maintaining calls is enormous.

Perhaps you may be able to talk to the dealer and see if there is a firmware update for the stereo itself, something they can do to enable this feature. But otherwise, no App can solve it alone.


MacBook: Prevent mouse from switching to external monitor placed above main display

May I suggest simply changing the arrangement of the screens (in the dialog seen in your screenshot, not physically).

You can either place the screen to the side, or even just place it at an offset. Say you place it as far to the right as possible (while remaining above the main screen). In that case, you could move the mouse from one screen to the other by going all the way to the right edge of the screen and up.


Command and Option keys on Windows keyboard

The Windows key will operate as the Command key, so cmd-c is win-c.

Further, the Alt key will operate as the Option key.


Smart Playlist in iTunes for songs without ratings

Just create a playlist with a rule matching ratings with no stars.


Click 'View' in the toolbar > Thumbnails. Then highlight the duplicated page, press delete to remove it.


Mouse Button 4 stuck on bind after deleting BetterTouchTool

There is a native keymapping tool within OS X itself in System Preferences > Keyboard > Shortcuts tab.  There is a slight possibility that the change was made there, and you can change it manually.

The more-likely issue is that the software was not uninstalled completely when removed from your Applications directory.  Lots of software nowadays comes included with uninstallers that you must run to remove stuff that gets distributed all over your filesystem (which is similar, yet not nearly as bad as the whole Windows Registry/AppData situation), yet I see this type of thing becoming more complex with each new version of OS X.

There is probably a .plist file out there somewhere that is getting loaded on startup or login that is controlling this unwanted behavior.  Personally, I would go about resolving this in 1 of the following 3 ways:

Re-download the app, and see if it comes packaged with an uninstaller.  If so, run the uninstaller instead of dragging the app into the Trash.
If the offending application did not come with its own uninstaller, download and install AppZapper, which is the absolute best uninstaller for OS X that I have come across to date.  If you are familiar with Windows, it is the equivalent of RevoUninstaller for Macs.  You simply open the AppZapper application, then drag the app from /Applications into the AppZapper window.  AppZapper will automatically include all files that got installed elsewhere on your filesystem (such as ~/Library/*/*.plist, etc.) that are related to that application.  Then simply click Zap! in order to remove all traces of its previous existence.  I have absolutely no affiliation with this app, but recommend it often, because it's simply a must-have for me and has saved me much grief in the past.
You can manually search out the offending .plist file, which is probably somewhere in ~/Library/LaunchAgents or ~/Library/LaunchDaemons, etc.  Sometimes they are hard to find and oddly-named.  First I would do a search for com.[better.touch.something.or.other].plist, but many times they follow the naming convention of the company or developer, which you may also try.

If all else fails, just sudo -s, start at / and start executing find commands (or better yet, in all of your Libraries -- if you are unlike me and remember where all of them are):

$ sudo -s
# find / -type f -iname "*.better*.plist" 2>/dev/null
# find / -type f -iname "*.btt*.plist" 2>/dev/null
# find / -type f -iname "*.boastr*.plist" 2>/dev/null

or maybe a better/faster way would be...

# find / -type f -iname "*Library*.plist"

...and see if anything stands out.  If so, make a backup just in case you are mistaken, and then delete that sucker:

# rm [offending file].plist


How to handle new image/video format of iOS on Linux laptop?

Here is the code / standard for the MPEG image container that Apple has widely adopted a bit earlier than others, but most major platforms should have good support these days.

https://github.com/nokiatech/heif

I would try this library if you can based on my trust in the Ubuntu community’s ability to vote up some great posts. (It appears Debian was patching HEVC in 2019 so you may already have the libraries you need once you know what to search for...)

sudo apt install heif-gdk-pixbuf

https://askubuntu.com/questions/958355/any-app-on-ubuntu-to-open-and-or-convert-heif-pictures-heic-high-efficiency-i

I do not have direct experience, so I welcome a big edit here or a better answer if someone has more direct experience.


Strange Process in Activity Monitor. Unable to search online

In my experience, that's a Safari Web Content process, although since you seem to be a Chrome user, it could also be Spotlight Web Content.


Is there a way to get OSX Finder to search through .ts (textscript) files?

Unfortunately Quicklook and Spotlight need to know how to look into a ".ts" file. Sounds like they are (essentiually...) a text file but you need a way to tell macOS that.

Over on Stack Exchange there was an answer to a similar question that might be of help to you. It does involve a project on GitHub and may involve some programming skills on your part to make it work with ".ts" files, but it seems like a start, at least...


I'm not sure but have you tried to put the global language of the iPhone in Arabic?
Applications can change behavior.


Jailbroken iPhone 3GS shows "No Service" after upgrading to iOS 6.1.6

Was the jailbroken phone also unlocked? If so, the phone has probably become locked again, and will only work with a SIM card after it has been unlocked once more.

This is because in some markets, phones are sold locked to a specific carrier, and will only work with a SIM for that carrier. If the phone is unlocked, it can be used with any SIM.

The unlocking process is separate to the jailbreak, and must be done after the phone is jailbroken.


Use Terminal to kill the Wine process.
From the Wine FAQ

10.2 Crashes and Freezes
10.2.1 My program froze up, how do I close it?
If you ran the program from a terminal window by typing wine
program.exe, you can usually just go back to that terminal window and
press Ctrl+C. If you ran the application some other way, such as from
a launcher shortcut, then you can open up a terminal and forcibly kill
the process:
killall -9 Application.exe

If you want to kill all Wine programs at once, you can run:
wineserver -k

You can also open up a Wine version of the Windows task manager by
running wine taskmgr in a terminal. This will allow you to kill
individual Wine processes.


Office 2016 on OS 10.11.6 - any known conflicts in 2017?

In my experience, Microsoft is investing substantial engineering, funding, resources, man and woman-power in to the Office 365 - Mac Office 2016 suite.

The updates are very rapid, easy access to pre-release and insider builds, well documented issues / workarounds.

https://blogs.technet.microsoft.com/office_for_mac_support_team_blog/
https://products.office.com/en-us/mac/latest-office-for-mac
https://products.office.com/en-US/mac/microsoft-office-for-mac

There's even a "back channel" admin and version tracking system that helps point power users to what changes when with respect to Office for Mac.

Are there known issues - absolutely. Even better, Microsoft documents them so people don't waste time troubleshooting things. Will one or more affect you? That's harder to tell, but we have thousands of daily users in our company using these apps heavily. The number of things we need to escalate to MS are few and far between and the time to fix things is superb. I personally prefer iWork suite, but Office and Microsoft have a huge lead from what I can see for most people's needs in the office space - Mac or iOS.


Most likely the owner of gping is not root so setting the S bit alone won't help. You need to change the owner to root first and set the S bit afterwards, you also need to make sure to change that on the actual binary not on any symlinks pointing to it.

I can't download the BootCamp support drivers (OS X 10.11.2)

I'm on a Mid 2012 Macbook Pro w/ Retina and El Capitan 10.11.2.

I was able to do boot camp assistant > download drivers (no other options selected) Bootcamp would ask for a usb drive, ignore it and close the pop up. From here I took my mouse up to the menu bar, and did Action > Download Windows Support Software.

The first time I tried this I got the error "The Windows support software could not be saved to the selected drive. An error occured while saving the Windows support software".

The second time I tried it, a day later with a reboot, I tried it again and it worked. Not sure what made the difference. Finder might have not been running as I'm running a trial version of Path Finder.


Will I receive all the SMS on my iPhone although it has been disconnected for some time?

Usually SMS messages have a 'lifetime' of around 9 days - this is set by the carrier.

iMessages should be delivered the next time you connect your iPhone to a network.


I have iPhone 5s and iOS 8.3 and my siri stopped working after replacing broken glass. My current workaround is to use the headphone microphone.

I think iPhone when using SIRI does some sophisticated background noise reduction. For that it uses additional microphones I think for iPhone 5s and up there are three all together.

Try to use the iPhone supplied Headset microphone I am certain this will work for you. This is my current workaround and it works all the time..


How to get rid of a widget stuck on the desktop instead of the dashboard?

Apple allows widgets to be displayed on the desktop in order to allow the people developing the widgets to test them without using Dashboard. Your system must have had that capability turned on somehow and that widget set to run on your desktop.
It's very easy to get the widget off of your desktop, and make it so that no other widgets will accidentally be relocated.

To get the widget off your desktop: click and hold on the widget, then press F12 to enter Dashboard. Once Dashboard is active, release the mouse from the widget. The widget is now docked in your Dashboard instead of on your desktop.

You'll probably have two copies of the widget in Dashboard now. You can get rid of one in the normal way (press the plus button at the bottom left and click the (x) on the widget).
You can also just hold down the option key over the widget and the (x) will appear.

Now, to prevent other widgets from escaping Dashboard in the future:
Open Terminal (/Applications/Utilities). Paste this in and press enter:

defaults write com.apple.dashboard devmode NO

If, on the other hand, you want to run some widgets on your desktop, you can run the above command with YES instead of NO.
Then, activate Dashboard, click and hold on a widget, exit Dashboard, and release the widget.


Will a mac ssd (it already have the os x) boot on a pc?

No, it won't boot natively, nor will it even mount on a Windows machine without a 3rd party translator 'plugin' to be able to read HFS+ or APFS.
Further, if it's APFS then I think only Paragon make a translator - APFS for Windows
They also do one for HFS, but I think there are other alternatives - HFS+ for Windows

Depending on what the macOS version was will depend on which of those you might need. HFS was default until Sierra, since then it's been APFS.


There are 3 kind of USB hubs.

Unpowered

Non-powered, or passive, USB hubs do not have an external power source and only pull power from the computer's USB port, limiting the maximum power to single USB (splitting).

Powered

Powered, or active, USB hubs use an external power source to bring each hub port to the same energy level as an on-system port, but not to charge them.

Powered with Charge capability

mostly have one (or more) of the USB ports capable of charging devices


Safari search suggestions reopen after search is completed

EDIT I thought I figured it out, but I tested with DuckDuckGo and it does not redirect you to a different domain. Yet the problem still occurs on that site. So the mystery continues. The first workaround might still work for you if you are using Google. The second workaround should work in any case.

I am able to reproduce this bug and have a few workarounds.

The reason this bug hasn't been fixed yet might be that it not always occurs when in full screen, you have to be in a different country than the U.S.A. too. It seems that the redirection to a different country domain causes this behaviour. I assume all the Safari developers reside in the U.S.A., so they never experience this behaviour.

Now for the workarounds:

Option 1

If you are using Google, visit google.com/ncr. This sets a cookie preventing redirection to a local Google site. The bug will disappear until you clear your cookies. There should be similar options for other search engines.

If you want it to disappear permanently or if you want to keep using your local site, we have:

Option 2

Add the AnySearch extension to Safari and configure it to use your search engine of choice. The bug does not seem to occur when using this extension.

I filed a detailed bug report with Apple btw. Hope it gets fixed in the near future.


Setting individual cap size on Time Machine storage on OS X Server

You could use Profile Manager in order to do so and setup individual limits per machine.

Login to Profile Manager and register your device (i.e. by downloading the profile to it) if not already done. Then you should be able to setup every single fine grained setting you want for that device without the need of any terminal-hacks or external tools.


How do I transfer my RSS feeds from Safari, now that it no longer supports RSS?

After installing an RSS reader, any attempt to open one of your existing feeds in Safari should open the RSS reader. For most readers, (e.g. Reeder) this will cause the app to ask if you want to subscribe to the just-opened feed. Once you've done that for a feed, you can delete it from Safari.


How do the cliclick and MouseTools command line tools differ?

cliclicl is the easiest one to automate your work.
However too simple.
for example, In your terminal cliclicl dc:. will do double click.

I recommend using cliclicl If your purpose is just double click.
Mouse tools is relatively complex.

Try cliclicl.
If you need more powerful tool for automate, then use Mousetools.


Show all windows on hover/click doc icon (Mac Yosemite 10.10.5)

Double tap (not click) the open application icon. This will display all open windows for that application and you can select the one you need.

If you are using a non-Apple mouse/trackpad you can right click or two-finger click an open application icon to reveal a list. The top entries are the open windows for that application. You can then select one of the open windows from that list.


Backquote (<) and ² inverted on my external keyboard

I've got the same problem on an external Italian Keyboard, as said in the comments by Tom Gewecke the problem was Karabiner.

I want to maintain Karabiner for one of the two keyboards so I've done a "simple modification":

You can do the same with your inverted keys.

Another solution of the problem is disable Karabiner for a specific Keyboard:


What's a good graphical SFTP utility for OS X?

Cyberduck (Free)
A great free FTP client. This is my go-to application. Anytime I need FTP access, I use Cyberduck. It's not quite as lightweight as Fugu, but it adds a lot more functionality than Fugu. I also really like the Growl integration with Cyberduck.

Fugu (Free)
Awesome little FTP client. As I noted above, this is a lightweight FTP client. It is great for simple FTP transfers and browsing. I do like the dual panel navigation.

EDIT: I forgot to add these.
Filezilla (Free)
I haven't actually used Filezilla extensively, but from what I've seen of it, I really like it. I downloaded it and played with it for a bit and I really like the tabbed connections. I also like the ability to jump to a path easily.

RBrowser (Free, $29 Upgrade)
A free FTP/FTP-SSL client. I don't usually use RBrowser because a $29 upgrade is necessary to unlock other protocols (Local, FTP/SSL/TLS, SFTP-SSH). I do like the Site Manager. It's a handy little thing to have.

I searched and came up with some other free FTP clients:
FireFTP (Free) - Firefox extension
The one downside I see is that this is for Firefox. The website doesn't make it clear how it works with Firefox, so I assume it is an extension.
Macfusion (Free)
This one relies on Google's MacFUSE. Since I don't know anything about MacFUSE, I don't know if this is good or bad.
Transmit ($34) By Panic
I have never used Transmit before, but I have used Coda and I definitely would recommend anything from Panic. The only reason I haven't used this because of the $34 price tag.

ForkLift2 ($30)
Never used it, just found it when searching.
Fetch ($24 per user)
An amazing program with a long, long, long mac heritage. It's way up there with Transmit by Panic and Interarchy as a file transfer program loved by long time Mac power users.
Flow ($30)
Never used it, but looks good from the screenshots. I really like the fact that it looks like Finder. I may have to give this one a try.

OneButton FTP (Free)
Just searching around and found yet another one...It looks pretty nice, except it's no longer supported. However, you can still download it.


You cannot partition a volume. You must partition a drive (device). To do so, click on the drive itself, located just above the partition you selected on the sidebar ("Samsung Portable...").

Then, you can partition the disk.

Edit: Back all data you want to keep up and Erase the disk as GPT (GUID Partition Table). Newer versions of DU for some reason don't want to work with MBR partition tables. Choose ExFAT as file system to be able to read and write to the disk from both Windows and macOS, or APFS if you only use Macs.


If you open Bluetooth to iMac and iPhone and also use the same Apple ID on both, these two device will “automatically” connect to each other.

But the usage of those connections are heavily limited. Here’s some example

Huawei mobile broadband E173 data card not working properly

I had a similar device. I will just post some insights I got using that.

Mostly I remember it didn't work when it wasn't plugged in at boot time. But I remember also similar problems as you describe.

Could you check next time it occurs to you quickly reboot and see if the problem persits?

Actually after some trying I found out that I could not only connect through the Huawei software, but also through the built in modem program of Mac OS. In the Network settings the modem showed up and I could connect from there - even automatically. This turned out less prone to problems. (How do you connect?)

Also I remember it was not easy finding current drivers (my provider didn't have any for Mac). In the end I ended up downloading the most current from another network provider and manually inputing the correct settings.


External DVD on Macbook Pro 2018 with multiport adapter

It seems solved by updating Mojave to 10.14.6.

Audio CDs work and most data CDs/DVDs work as expected.

Only RW disks seem difficult to read, but this seems a completely different problem.
So it seems that using a multiport adapter can help connecting a USB CD/DVD drive.


How to delete iCloud storage Mail cache?

I found a solution to my problem. So for future readers:

Mail is caching (Bug?) the storage space in Mail. So after deleting a few thousands E-Mails, the space is still taken.

The solution:

  Insert a few E-Mails back in archive. After importing a few E-Mails
  again, Apple is updating the cache.

Guide:

  Deleting every E-Mail in archive
  Spotting that the space is still taken
  Insert 3-4 E-Mails back to archive
  Waiting until the space is updated (look at iCloud.com)
  Deleting the 3-4 E-Mails in archive


How to map "$" character to "€" on French AZERTY keyboard

You can easily make a custom input source with the mapping you want with Ukelele.


How does my dual core i5 in my MacBook Pro have more than 400% CPU usage?

If you look here, you have 2 cores that can execute 2 threads each with turbo boost.  So I would assume 400% is your maximum.  Seems likely that Adobe maxed out one CPU completely, and the other CPU was running the OS and other tasks.

The additional usage may be because your 2.7 ghz CPU was turbo boosted to 3.1 ghz at the time.

Also, within Activity Monitor, you can choose Window -> CPU History, and it will break down everything.  For example on my 6 core Xeon, I have 12 graphs.


CMD 2 keyboard shortcut no longer working

One common cause of a single key combo not working is that it gets set as the trigger for Text to speech or for Speech Recognition.  Double check system preferences/speech


Does enabling Enhanced Dictation in Mac dictation improve the speech recognition accuracy?

According to that link, it affects only speed, duration & offline ability, not accuracy.

It downloads the database locally to your machine, allowing the Mac itself to do the work, rather than having to send it to Apple.

Presumably, though it's not mentioned, the learning accuracy will still improve over time, as it learns from its mistakes.


Go to settings -> Tap on your name -> Tap on iCloud -> Tap on Storage or Manage Storage and then you'll be able to see how much "iCloud storage you have available.

Your iPhone storage is different from your iCloud. What you can do though is while you are in iCloud settings, go to Photos (in iCloud) then put a check next to "Download and keep originals". That will make sure the photos save in full quality. This will also eat up your iPhone storage depending on how many photos you have.


Does iCloud save deleted pictures from your camera and photo stream?

Heard that iCloud automatically backs up your iOS device information daily over Wi-Fi when your device is turned on, locked, and connected to a power source. On your iOS device, go to Settings > iCloud > Storage & Backup, then turn on iCloud Backup.


Make dock appear on both screens at the same time

tell application "System Events"
    tell dock preferences
        properties
    end tell
end tell

This is everything supported natively:

{minimize effect:genie, magnification size:1.0, dock size:0.321428567171,
autohide:false, animate:true, magnification:false, screen edge:bottom,
class:dock preferences object}

Plus, as purely a philosophical question, the Dock can not be displayed on both screes at the same time.

Suppose you have one Dock per display. If you have cursor focus on display 1 (i.e. Menu Bar is not greyed/faded out), you move the cursor to display 2 with its greyed out Menu Bar and click on a Dock to launch a new app.

Where should the new window go? It should go to display 1 because display 1 has the focus. Yet it should also go to display because it's where the Dock that launched it is at.

Take a step back, there is another question. What should happen when you click on Dock on an unfocused display? Shouldn't focus be switch to the Dock/display before anything else? So launching an app is a double click process. Or more precisely, single-click if the display is in focus, double-click if not. And how do you tell if the Dock is in Focus? Move your eyes all the way up to Menu Bar (or Window Bar of frontmost window).

This is not an issue on other OS's. This mess can be trace back to when OS X compromised window focus long ago by place Menu Bar on top instead of in window. Not able to have multiple Docks is one small ramification of that design decision.


Mission Control view programme icons missing. How can I get them back?

You have the "Group windows by application" option turned off – this tiles every window individually so that nothing overlaps (this is how Exposé used to work in OS X 10.5 Leopard and earlier).

When "Group windows by application" is on, the tiled windows are stacked in groups based on which application they belong to, and the application icon is overlaid on the group, as in your second screenshot.

To enable "Group windows by application", go to the Apple menu > System Preferences > Mission Control and check the box.


Is there a simple MacOS Bluetooth Toggle Shell Command?

There is a third-party utility named blueutil that makes it easy:
blueutil --power toggle

Toggles the Bluetooth power state.
See the Usage section on the linked webpage for additional usage information.
Note: If you do toggle the power state, turning Bluetooth off, make sure you can control your Mac's keyboard via USB or built-in if a notebook.


What does "Other Languages" item in iPhone settings mean?

The Other Languages... item under Language & Region lets you configure your device to work with other/additional languages.

As observed under Other Languages... screen, there are two section. This means that there's two kind of support for languages. For the sake of understanding let's call them as below:

Full support

and

Partial support

The languages listed under the first section, IPHONE LANGUAGES are fully supported by iOS, the operating system running on your iPhone. This means that if you select a language from this list, most of the textual items/instructions in your iPhone will use that language. Basically, selecting a language from this list lets you change the device language.

You may wish to refer to the Apple Support article, Change the language on your iPhone, iPad, or iPod touch

On the other hand, the languages listed under the second section, OTHER LANGUAGES aren't supported fully by iOS. This means selecting one from it won't change the interface language of the device and you'd continue to see the textual items/instructions in your iPhone in the language selected in first section (device language).

However, the selection from OTHER LANGUAGES list is used by internationalized apps and websites. If you select a language from this list, apps and websites with content localized in it will be display it in the selected language.

When setting it up for the first time, your iPhone chooses the default language as device language corresponding to your locale.

  A follow up: When I develop an app or website for iOS, languages of which list should I be aware of?

A generally followed practise is to create the app (content) in English and localize it to work with all the languages your target audiences uses/expects to use it in.

It is recommended to refer to the Apple Developer document, Internationalization and Localization Guide


How to use a MBP with broken graphics chip as a server?

Build the drive with the software on a separate machine or remote log in to it and set it up that way.

I have 2 machines I remote log in to but not due to a graphics failure so I can't say if it will have an error on booting


I had a similar problem. Have several contacts in Serbian (cyrillic) others in English. I solved the problem by adding to each contact written in cyrillic new fields for phonetic spelling for the last and the first name.


If the folders are the same name, drag one to the location of the other, and BEFORE releasing the mouse or trackpad, hold down the Option key. You will be presented with three options, one of which is to Merge.


Could the recently announced Mac Minis power a theoretical 5K Retina display?

Doesn't look like it.
Best info I can find says it can do 3840x2160 resolution at 30Hz
Everymac hasn't been updated to include them yet, this was from zdnet - http://www.zdnet.com/new-improved-slower-mac-mini-7000034795/


In SystemPreferences->General check "automatically hide and show the menubar".
Then it works like this: you do the app full screen with the green button, the menubar is hidden, move the mouse pointer to the top of the screen and the menubar becomes visible above everything.
added: It works also even when you do not check "automatically hide and show the menubar", a tid bit slower perhaps.
added; you can also set a key combination if you want.


Once you delete any application (in this case, Youtube), you will lose all the data that application has. But with the introduction of iOS 11, Apple added a new feature that would allow you to keep an application's data intact while deleting the application itself. If you have iOS 11, to do this:

Open Settings app and navigate to "General > iPhone Storage"
A list of apps will appear shortly. Choose the application you want to delete.
Press "Offload App". This will delete the app, leave it's icon on the screen, but it will be reinstalled when you try to open the app. Your data is still intact on your phone, but the app is now deleted. I hope this is what you wanted.


open iTerm drop down console on different screen

iTerm2 Build 1.0.0.20130319:

Iterm->Preferences->Profiles->Window

From there you have a screen bar you can set to 'screen2' or 'main screen'.


Try logging out and back in (or, if you're comfortable with the Terminal, try running killall Dock). That will cause the Dock to relaunch and may un-freeze it.


iPhone backup error. What does this mean?

Presuming you already have a valid backup of the iPhone, give phoneMiner a try (trial download on their site). It will scan for any previous backups and if they exist allow you to extract your contacts/photos etc.


I too have had this problem since I updated. Usually I find it's just some serious lag ad if you wait it out results will show up. If not there may be a bigger problem with your iPhone. Or you might just need to do a good old software update!


iPod Nano battery loses charge when it's cold

The temperature you describe is not cold enough to affect battery functions too much. It’s within the operating temperatures and it shouldn’t happen. Take a look at the temperature charts in the Apple iPod Battery page and if it doesn’t perform as expected, contact them immediately.

UPDATE: If the iPod is not under warranty, you’re pretty much “hosed”, however, you can attempt a manual battery replacement. This google query is a good starting point.


iOS 10: Storage Almost Full Warning (But I have free space)

I have reset the iPhone from the iPhone's setting (because I did not want to update the phone), but in order to truly clear the caches and space, I had to reset (and update) using iTunes.


Late-2011 MacBook Pro’s and Snow Leopard

I personally haven’t done this but from research it is possible:
This article helped

Method 1: If you have no cooked backup of your drive
This method will wipe your Mac but you can do a backup:

You should backup the locations where your documents, music e.t.c are stored to an external drive

Next insert the snow Leopard disk, restart your Mac and hold down c too boot to your dvd drive

Once the installer appears, go to utilities in the menu bar and click disk Utility

Find the drive in the sidebar where Lion is installed, select it and navigate to the Partition tab.

Click on the drop down menu under Partition Layout and select “1 Partition.” Hit Apply.

Now navigate to the Erase tab and make sure “Mac OS Extended (Journaled)” is selected, then hit Erase to delete all data on the
drive.

Quit Disk Utility to get back to the Snow Leopard installer and proceed with the install.

Restore your User folder and documents from your backup.

Run Software Update to get  everything current, install your apps  from your original install media and  update those as well.

Method 2: If you managed to clone  your drive
A popular option for cloning your drive is Carbon Copy Cloner, which
is a handy utility to have for any Mac owner. Assuming you’ve done
that, follow the directions above to get your drive primed and ready,
but stop at step 6 and follow these instructions instead.

Attach the drive containing your  CCC clone to your Mac.

Open System Preferences, then  go to the Startup Disk preference  pane.

Chose your CCC external drive  as the startup disk.

Restart and launch CCC, then  choose your backup from the  “source” menu.

Select your Mac’s internal drive  as the destination.

Chose “Restore items from a  backup” from the settings pop-up  menu and hit the “Clone” button.


iCloud unlock with new Apple ID's password

Yes, the login will authenticate with Apple's servers to verify the password, ensuring it is verifying the latest possible password, hence the network requirement.


What password does OSX Server use when importing SSL certificates?

It looks like OP's problem has been solved, but for the record it's actually fairly easy to get the keys from OS X Server, as long as you have admin access to the server. I'll give you two ways to do it:

Run the Keychain Access utility on the server, select "System" from the Keychains list, then "My Certificates" from the Category list under that. Select the relevant certificate on the right side of the window, then from the File menu choose "Export Items. In the export dialog, make sure the file format is set to "Personal Information Exchange (.p12)" to export both the private key and (public) certificate. It will ask for your admin name & password to get access to the keychain, then ask for a new password to encrypt the exported file with.
The certificate and associated private key are also stored (as you said) in /etc/certificates. Make sure you get both the certificate (filename ending ".cert.pem") and matching private key (".key.pem"); you might also need the cert chain (".chain.pem"), which includes your certificate and the supporting certificates that vouch for its authenticity.

The private key file will be encrypted with a randomly-generated password. No problem; in order for server services to use this key, its password is stored (in the system keychain, actually) in a retrievable form. With admin rights, you can retrieve it the same way the web server does. Use this command (replacing server.example.com with the actual domain name):

sudo /Library/Server/Web/Config/apache2/getsslpassphrase server.example.com:443 RSA

It'll require your admin password, then spit out what looks like a GUID. That's the encryption password for the .key.pem file.

(Note: in older versions of OS X Server, getsslpassphrase was in /etc/apache2/ instead of /Library/Server/Web/Config/apache2/. Adjust as needed.)


How can I find Bottom Rubber Feet Foot For MacBook Pro 15" A1398？

Apple actually has an article specifically about this, right here.  Apparently they have a rubber foot replacement kit which you can get if you contact them and request it.

Personally I would just find some soft-side velcro, felt, or some other craft material, cut out a few small circles with an xacto-knife, glue it on with Loctite (which is what Apple uses according to their article above) and call it a day.

If it really bugs you and you want someone else to cut out the little circles for you..

How do spam email accounts get onto devices?

Check http:// minbox.email/join#/ (not linking them here though, don't want to generate traffic to their site); they offer a free email inbox in exchange of receiving spam. As of how they configure the email account on your device, it appears that it is made through a Configuration Profile.
I tried to verify myself by creating an email but couldn't end the process because of an error on their end.

You or anyone can create a configuration profile to

  (...)quickly distribute groups of settings and access powerful
  management features that aren’t normally available.

Then

  You could email the configuration profile to someone–including
  yourself–or offer it for download on a website. When someone taps the
  email attachment in the Mail app or downloads the configuration
  profile file from a website, they’ll be prompted to install it on
  their iPhone or iPad.

(from this article).

Note that your mother would have had to accept the prompt in order to apply the Configuration Profile.

It's also important to understand that this may be a vehicle for malicious configurations as explained in this article.

Can I increase RAM from 8GB to 16GB on this model?

No, you can't! As stated in Apple MacBook Pro 13-Inch "Core i5" 2.3 Mid-2017 Specs:

  This notebook also packs 8 GB of onboard 2133 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of purchase [for US$200], but cannot be upgraded later)

In a teardown of a similar notebook (a MacBook Pro 13" Touch Bar 2017) the RAM is visible outlined in green - it's apparently soldered:

How to safely install rEFind from recovery mode?

Though you shouldn't see this message (even with SIP enabled) in Recovery Mode you can type Y and continue installing rEFInd.

A less rocky but time consuming way is to disable SIP in Recovery Mode by entering csrutil disable in Terminal.app.

After rebooting to your main boot volume open Terminal.app, enter csrutil status and if SIP is disabled, install rEFInd.

Then reboot to Recovery Mode again and enable SIP again with csrutil enable. After rebooting you should get the rEFInd boot window.


You can check the S.M.A.R.T. status of the disk with a tool like smartmontools!

To get the details simply enter smartctl -a disk0. You may have to enable S.M.A.R.T. with smartctl -s on disk0.

The IDs may differ from vendor to vendor and disk model to disk model.

Obviously this is an older disk because of the Old_age tag in the type column.

The best indicator is probably the Host_Writes_32MiB count which is (430139 * 32 MiB) ~14.4 TB. This is almost the 30-fold of the disk capacity.

The Bytes written may have another ATTRIBUTE_NAME on your disk: other commonly used names are Host_Writes_MiB (multiplier: 1.04858 MB) or Total_LBAs_Written (multiplier: 512 B or 4096 B).

If the technician or yourself restored a backup of the old disk to the new disk or installed a new system you can expect the write count to be the "Used" disk space (Disk Utility or Finder Info) and depending on usage about 1-15 GB per day.


The least expensive mac is the Mac mini. It comes without a monitor, keyboard, or mouse so you can use the items from your PC. A new Mac Mini sells for $800. If that is still too pricey you could maybe find a used older mac on Ebay or similar sites. Beware because Macs have a high resale value. So always check the price.
If your needing the latest XCode, be sure that the computer can run Mojave or Catalina operating systems. A computer from 2013 or later should be fine. If you are just learning to code then you can maybe get a cheap laptop or the Mac Mini.
You should check the Apple site to confirm what models can run the latest version of Xcode. My 2013 number was just from memory. The actual compatibility list is given below.
MacBook (Early 2015 or newer)
MacBook Air (Mid 2012 or newer)
MacBook Pro (Mid 2012 or newer)
Mac mini (Late 2012 or newer)
iMac (Late 2012 or newer)
iMac Pro (2017)
Mac Pro (Late 2013, plus mid-2010 and mid-2012 models with recommended Metal-capable GPU)


How to install a specific version/build of Safari?

I do not think you can find level of builds for Safari. As long as you are running the current latest version of Sierra, You will have the latest version of Safari.

To find the latest updated version and patch details you can track them on Apple Support.

The last updated for Safari came on 15 May 2017 - Safari 10.1.1

Supported OSes - OS X Yosemite 10.10.5, OS X El Capitan 10.11.6, and macOS Sierra 10.12.5


Methods for copying Time Machine backups offsite

If I understand your question correctly (and I may not) you would prefer a cloud solution but would be willing to consider another non-cloud offsite solution.

My preference is not to use the cloud for this type of backup. The cloud is fine for low volume data storage and file services (e.g. Dropbox, iCloud, Google Drive, MS OneDrive, etc), but for this type of backup it's not (at least not yet).

Instead, my recommendation is to do something similar to what I am doing. By way of example, I'll explain how I do this for my iMac (but I follow a similar process for all my machines!)

This iMac has a 500GB HDD
I have purchased two portable USB 2TB external hard drives
I have labelled these hard drives as iMac TM Backup HD 1 and iMac TM Backup HD 2
I set both of these external drives to be TM backup drives
As both drives are set up with TM they are alternated whenever both drives are available
Once the initial backups are done, I physically remove one of the external drives and take it 'offsite'
On the same day each week, I then swap them over
The net result is that both hard drives will have backups in the order of one week on, one week off (but between them I have a full set of backups).

Now, in terms of keeping one of them offsite, you have a number of options. Over the years I have used as my offsite location any of the following:

My workplace
A shed in the back yard
My car (but this may depend on your climate and where you 'garage' your car)
A family member's/friend's place (assuming you trust them!)

Basically, the idea is that your offsite drive is somewhere that protects your data in the event your house burns down or you get robbed. My strong suggestion would be in a locked drawer at your workplace (unless you work at home). Most people's workplaces are air-conditioned, secure, and convenient.

IMPORTANT NOTES ABOUT STORAGE

Regardless of the 'offsite' location you choose to keep your hard drive, there are some key factors to keep in mind:

Always keep the drive safe from large magnetic fields!
Ensure the location has a temperature range between 10 degrees celsius (50 degrees fahrenheit) and 43 degrees celsius (110 degrees fahrenheit). So, keeping it in a car would usually not be a good idea.


Your ringer volume adjusts the volume of the sound coming out of the phone when it's ringing. If the phone is not playing media (i.e. no sound is coming out of it) then the volume buttons on the side adjust the ringer volume.

If you are playing media (music, video, etc) out the internal speakers, then the buttons on the side adjust the volume of that media coming out those speakers.

Finally, when you have headphones plugged in, the iPhone knows this and has a separate volume for headphones. Using the volume buttons will adjust the headphones volume when headphones are plugged in.

The reason why these are separate is because sometimes you want to mute your ringer, but still want to listen to media (or vice versa), and because the headphone and internal speaker volumes are different and need to be adjusted separately.


Is there any AirPort product that supports to receive audio streaming and share a hard drive on USB?

Your impression is correct. AirPort Express's USB port does not support hard drives, and AirPort Extreme doesn't have an audio output jack:

Sucks, don't it?


Finder windows moving from other monitors as soon as the computer hibernates

Found this apple discussion thread about your issue:

  First you need to open Mission Control and add a new "Spaces" now just
  called a "Desktops" to both screens. You don't need to use these new
  Desktops, they just need to be there. With two monitors you end up
  with "Desktop 1" and "Desktop 2" on the first monitor and "Desktop 3"
  and Desktop 4" on the second monitor.

  Right click the Dock Icon for that application you want to launch in
  the second screen and choose Option. Now you can assign the
  Application to always open on the second Desktop.

  Without having multiple Desktops established, this option isn't
  available. It looks like a bug to me.


Quote from Apple page http://support.apple.com/kb/HT5887?viewlocale=en_US&locale=en_US

  You can't use AirDrop on iOS to share with OS X users, and OS X users can't use AirDrop to share with iOS devices.

Airdrop between iOS and OS X will be available from iOS8 and Yosemite.


You can run the shell command /usr/bin/textutil  in the Terminal.app found in /Applications/Utilities/

textutils  Can be used to convert the text from one format to another.

But it also can  "Read the specified files, concatenate them, and write the result out as a single file in the indicated format."

/usr/bin/textutil file/s -cat convert to format -output file output path

It will concatenate differently formatted files.

The formats textutils can read and write to are

txt, html, rtf, rtfd, doc, docx, wordml, odt, or webarchive

Example

/usr/bin/textutil foo1.txt foo2.txt foo1.rtf foo.html -cat txt -output /file/path/foo.txt


Reset or access administer password on Macbook Air

After doing some researching, this was the case of the Mac being used for school ( or it being a school computer )

Schools and other enterprise setups often will set a firmware password to prevent things just like this from happening. If your Mac was manufactured before late 2010 (Apple menu > About This Mac), you may be able to reset it by pulling out the RAM. I'd recommend that you follow the instructions outlined here and use disassembly guides from iFixit.

Otherwise, your Mac is locked and cannot be recovered without proof of purchase. In terms of ethics, I'd recommend trying to figure out what school it came from and contacting them about this, as this is considered stolen property.


Force FileVault to use 256-bit key encryption

Most documentation I'm finding seems to indicate that the key's used in macOS 10.9 and higher use a 256 bit key by default.

  Encryption and authentication support

  FileVault 2 uses the Advanced
  Encryption Standard (AES) encryption algorithm, which delivers robust
  protection for stored data. Until mid-2013, it only supported the use
  of 128-bit keys, not 256-bit keys. Although 128-bit keys are
  technically acceptable in many environments, organizations are rapidly
  moving toward 256-bit keys to thwart emerging threats.

  The latest versions of Mac OS X, starting with 10.9, support 256-bit
  AES keys, so organizations wishing to enable FileVault 2 on legacy
  systems should be cautious about the 128-bit key strength present in
  older Mac OS X versions, Lion (10.7) and Mountain Lion (10.8).

Reference: Apple FileVault 2: Full disk encryption software overview

This PDF and the Wikipedia page seem to indicate this as well.

How to restore game progress in OS 9.1 after reinstalling deleted app

At the time of deleting the app there was a popup: "Remove Angry Birds from Game Center?  You will no longer be listed on leaderboards for Angry Birds.  Keep / Remove".

If you clicked "Remove", there is no possibly recovery for your game data in iCloud.


Facebook iOS app won't connect unless wi-fi enabled

The only possible thing that I could think of is that you may have disabled maybe accidently Cellular Data for Facebook and to verify you could go into Settings -> Cellular and verify that under USE CELLULAR DATA FOR: is turned on for Facebook.

Another rare possibility could be that there might be a DNS issue with your cellular data provider whereas it wouldn't be able to reach Facebook on its own network.


What is lsof -i | grep -E "(LISTEN|ESTABLISHED)" composed of?

First lsof is executed:

lsof - list open files

with the option -i:

  -i [i]   selects  the  listing  of  files any of whose Internet address
                  matches the address specified in i.  If no address  is  speci-
                  fied, this option selects the listing of all Internet and x.25
                  (HP-UX) network files.

So you get a list similar to this:

Safari      252 pfitz   33u  IPv4 0x1052718d4b4f54ef      0t0  TCP localhost:49289->localhost:6263 (ESTABLISHED)
Safari      252 pfitz   36u  IPv4 0x1052718d4b4f54ef      0t0  TCP localhost:49289->localhost:6263 (ESTABLISHED)
iTunes      254 pfitz   28u  IPv4 0x1052718d460f9d07      0t0  TCP *:49196 (LISTEN)
iTunes      254 pfitz   30u  IPv4 0x1052718d460fb4ef      0t0  TCP *:daap (LISTEN)
iTunes      254 pfitz   31u  IPv6 0x1052718d37b6b627      0t0  TCP *:daap (LISTEN)

with a lot more entries. To filter the entries one uses grep:

  The grep utility searches any given input files, selecting lines that
  match one or more patterns.  By default, a pattern matches an input
  line if
       the regular expression (RE) in the pattern matches the input line without its trailing newline.  An empty expression matches every line.
  Each
       input line that matches at least one of the patterns is written to the standard output.

  grep is used for simple patterns and basic regular expressions (BREs); egrep can handle extended regular expressions (EREs).  See
  re_format(7) for
       more information on regular expressions.  fgrep is quicker than both grep and egrep, but can only handle fixed patterns (i.e. it does
  not interpret
       regular expressions).  Patterns may consist of one or more lines, allowing any of the pattern lines to match a portion of the input.

and the option -E does the following:

  -E, --extended-regexp

  Interpret pattern as an extended regular expression (i.e. force grep to behave as
  egrep).

The regex in this case is "(LISTEN|ESTABLISHED)" which means just print the lines with listen or established.

Conclusion

lsof builds a list with all Internet connections.
To be useful it needs to be filtered with grep
So it gets filtered with the regular expression which is looking for either LISTEN or ESTABLISHED


Will I lose some settings/configurations?
No.

Do I need to back up some data?
Well, you should always have backup of important data. When it comes to SMC reset it does not touch your storage/hard drive. So no data should be affected.

Is there any risk that the system will not work properly after the reset?
There is a very slight risk. In 99,9999% of all times, if the computer are working perfectly and has no hardware issues the computer till work 100% properly after SMC reset. However there has been cases where the SMC reset fries the logic board, although, those cases had shown other hardware symptoms.

The SMC is responsible for these and other low-level functions:

Responding to presses of the power button
Responding to the display lid opening and closing on portable Macs
Battery management
Thermal management
The SMS (Sudden Motion Sensor)
Ambient light sensing
Keyboard backlighting
Status indicator light (SIL) management
Battery status indicator lights
Selecting an external (instead of internal) video source for some iMac displays


Windows 10 install very slow on Mid 2012 MacBook Pro

It had something to do with the problem I solved here:   HGST 1tb in mid 2012 mbpro not working in sata bay but drive seems fine.  After I solved that issue, the Windows install worked normally again


Step one on the Mac might be to sign out of iCloud. AirDrop uses that.

Before doing anything, make a full backup of the Mac. Then check for other user accounts on the Mac in system preferences. Once you're sure your account is the one doing the naming for airdrop, you can see if your iCloud contact details are correct and sign out (deleting any iCloud data on the Mac when prompted since that data is in the cloud) and then sign back in to iCloud.

Worst case, once you've singed back in, check the Contacts app and check that "your card" is really your information. Search for "My Card" in contacts app help if you aren't sure how to find that menu option.


The answer as I have now discovered is that .icloud files are the metadata that precedes the full file being downloaded to a device.


iPhone is not discovering available devices in Bluetooth settings in iOS9

If you follow central - peripheral concept, then one device should start advertise service and and another device should start scan for same service.
Then it will show as discovered.


Where is the "Open in Low Resolution" setting stored for an app?

Where is the “Open in Low Resolution” setting stored for an app?

When checking/unchecking the Open in Low Resolution checkbox on an App's Get Info window in Finder, an entry is created/modified under LSHighResolutionModeIsMagnified in the following file:
~/Library/Preferences/com.apple.LaunchServices/com.apple.LaunchServices.plist

In the image below, Item 1 showing a value of 3 is when checked, and 2 when unchecked.

Update to address comment.
From Terminal:
$ defaults read ~/Library/Preferences/com.apple.LaunchServices/com.apple.LaunchServices.plist
{
    LSHighResolutionModeIsMagnified =     {
        "com.adobe.adobeconnect.app" =         (
            <626f6f6b ...>,
            3
        );
    };
}
$

Note in the above output that the value of the first item of the array is truncated to <626f6f6b ...> for brevity.
Also note the difference in how Xcode displays the contents of the PLIST file verses the defaults command in Terminal.
If using the PlistEdit Pro application, it will show the elements of an array with just a numerical value as its label while omitting the word item.

In either case using a GUI both labels are virtual and do not exist in the actual data structure of the array. Only the output of the defaults command represents an accurate data structure of the data itself.

Tested on macOS High Sierra.


What Is the Keyboard Shortcut for Sleep Display Without Eject Key?

(At least on the Retina display MacBook Pro) use the Power button the same as you previously used the Eject button. So Control ⌃+Shift ⇧+Power puts the display to sleep and Command ⌘+Option ⌥+Power puts the machine to sleep.


How do I unlock a .plist file so that I can change it?

Before you do this make sure there are no running instances of TextEdit on your system.

Using The Finder

Select the plist file in the Finder and doing File > Get Info. At the bottom of the file info window you'll see a section called Sharing & Permissions. You want to make sure you're in that list and that you have Read & Write level access to the file.

Before you can add yourself to the access permissions on the file though, you'll need to unlock it. Click the little lock icon (1) in the lower right hand corner and enter your password. If you're not an administrator on the machine, you won't be able to proceed past this step.

Once you've unlocked the file you can change your permissions to Read & Write. If you're not shown in the list of people who can access the file, click the + button below the list and find yourself in the Users & Groups list that pops up.

The changes are applied to the file as soon as you make them in the File Info window.

You should now be able to open, edit and save those edits to the file.

Using The Command Line

Open a Terminal window.

Change to the place where the plist file is located:

cd ~/Library/Preferences/

Change the ownership and permissions on the file so you can read and write it:

sudo chown $USER aomDSP.plist
sudo chmod u+w aomDSP.plist

You probably don't need sudo on the second call there, but it can't hurt. You'll need administrator access to the machine to do this.


Stop sign when booting from internal ssd, boot goes fine if the ssd is in external case

The problem was a faulty SATA cable. I got a replacement and everything is now working flawlessly.


Ubuntu not booting after cloning (OSX and Kali)

OK, after searching for 2 days I finally got the answer.

So I had a bootable apfs OSX partition with rEFInd installed from OSX. rEFIND couldn't find ext4 partition from OSX natively. That was the problem. ext4 partition was cloned from source later on.

Download Kali live-USB, mount it using dd or rufus or any other software.
Reboot, Hold alt to boot from Kali USB, then follow the instructons from here https://medium.freecodecamp.org/kali-installation-on-usb-stick-with-pure-efi-boot-on-a-mac-37585b7698e2 section "Boot from Live GRUB".
After you log in (here's the main trick): download a debian version of rEFInd (.deb)
and install it:

sudo dpkg -i DEB_PACKAGE

Reboot. Your Kali partition should appear on rEFInd boot menu together with OSX.

iPhone can still connect to my WiFi, even though the password was changed

If you put that password into a different Apple device then that password will be accessible to the phone over its cellular data connection, assuming that they are both using the same Apple account.

Macbook Air screen fading randomly between off and full brightness

Could be hardware, overheating or simply a stuck function key. I would try cleaning it (especially between the screen and the base where the vent is) and making sure keys are not gummed up. Then test the hardware using

Based on nohillside's answer and Matthieu Riegler's answer, this is my solution:

cd /

    /Applications/Inkscape.app/Contents/Resources/bin/inkscape $i --export-pdf $i.pdf
end
cd /path/to/folder
launchctl limit maxfiles 10240 10240

Adobe applications - Case-sensitive volumes not supported

Here's what Adobe has to say about this error.

It means you have to reinstall OS X.

Reformat and Choose OS X Extended (Journaled) as in the image above.


Test iPhone SE without a battery. Possible?

The battery is required to boot the device. Once it has booted, you can leave the Lightning cable connected and then disconnect the battery.


I used the hacky workaround in this post on my slightly older Macs and it worked like a charm.

  Turn OFF Notification Center Permanently

  Here's the best way to permanently kill the Notification Center. Open the terminal and type:

launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist

  The Notification Center icon will disappear from the Menu bar at the top. There will be a visible gap, but the system will close it up the next time you click the mouse. Notification Center has been terminated.

Built-in display resolution resets when connecting to external monitor

I have got the same problem. It is not that big of a deal to change it everytime, but it still is pretty annoying.

Sometimes it doesn't happen, but most of the times it does.

This morning when I turned on my macbook, it started in my "more space" resolution.
When I connected my second screen, display mirroring was turned on (something I never use and don't want). When I turned off display mirroring, my Macbook display went to the default resolution. I changed it back to "more space".
Then I unplugged the second monitor. After my Macbook's screen went black, it returned in the default resolution again. I changed it back to "more space".
Then I replugged my second monitor and this time it remembered my "more space" setting. I then unplugged the second monitor again and again it remembered by "more space" setting.

It seems as though it remembers the settings until I completely shut down my Macbook. Then, it reverts to the default settings (and sometimes randomly turns on display mirroring).
I have to test this thesis more to see if I am correct.


What makes macOS 11 Big Sur supported on a 2013 MacPro and not a 2012?

As to the reason why Apple chose this exact model as the cut-off point for support cannot be answered by anyone but Apple. Everything else is just speculation.
There exists an non-official guide on how to install the Big Sur beta on the older 2010/2012 Mac Pro's (amongst others):
https://parrotgeek.com/bigsur/
Note that because this is non-official, it might not work or exhibit problems. Also it might only work for the current beta, and not when you get to the final release of Big Sur.
As indicated in this guide, the built-in WiFi does not and there could be issues related to sleep mode. This could hint at why Apple does not support this model - i.e. having to support these older WiFi chipsets.


iOS: block ads in Apps without Jailbreak and VPN tunnel (normal 3G/4G network)

No, because apps aren't able to inject themselves into other apps without jailbreaking, they are only able to use Safari Content Blockers in Safari or routing network traffic through a VPN.


External hard drive knocks out wifi Internet

If one of your external drives is connected using USB 3, then this is most likely the culprit. If the shielding has degraded on the USB 3 cable then it can interfere with your wi-fi. If you external has any other type of connectors, i.e., USB 2 or FW800, switching to that will solve your problem.

This excerpt from this PCMag article explains why this can happen...

  USB 3.0 has a 5Gbps signaling rate. The USB 3.0 specification requires
  USB 3.0 data to be scrambled and it requires spread-spectrum. The
  noise from USB 3.0 data spectrum can be high (in the 2.4-2.5GHz
  range). This noise can radiate from the USB 3.0 connector on a device
  (such as a PC or Router), the USB 3.0 connector on the peripheral
  device or the USB 3.0 [port]. If the antenna of a wireless device
  operating in this band is placed close to any of the USB 3.0 radiation
  channels, it can pick up the broadband noise. The broadband noise
  emitted from a USB 3.0 device can affect the SNR (signal-to-noise
  ratio) and limit the sensitivity of any wireless receiver whose
  antenna is physically located close to the USB 3.0 device. This may
  result in a drop in throughput on the wireless link.


Mail app no longer automatically creates clickable hyperlinks when pasting a URL. How do I fix it?

Acutally they just changed the default setting... In Mac Mail Just go to the menu "edit->subsistutions->smart links" and click on it if it's unchecked to active the feaure.

After that you can paste or type links and it will do the add link operation automatically.


I want to change the sound of outgoing mail on my Macbook but I seem not have permissions and have yet to find a work around, any ideas?

Catalina and later have a read-only System volume filesystem layout. Mail.app resides on that volume (at /System/Applications/Mail.app). You will need to remount the System volume as read-write in order to modify Mail's bundle.
EDIT:
To elaborate, here are the steps:

Reboot into the Recovery OS (hold CommandR during boot).
In the Recovery OS, open Terminal (Utilities -> Terminal).
In Terminal, run: csrutil disable
Reboot into Single User Mode (hold CommandS during boot).
Remount the root directory as read-write: /sbin/mount -o rw /
Make your modification to Mail.app (e.g., cd /System/Applications/Mail.app/Contents/Resources && mv "Mail Sent.aiff" "Mail Sent-ORIGINAL.aiff" && cp /path/to/YOUR_NEW_SOUND.aiff "Mail Sent.aiff" && chown root:wheel "Mail Sent.aiff" && chmod 644 "Mail Sent.aiff")
Reboot: reboot

Replace /path/to/YOUR_NEW_SOUND.aiff with the actual path to your desired AIFF file.
