Is there any way to review all file moves done with Finder?

There’s no need to review since Finder cleans up a bulk move almost always and when it doesn’t - you will see the files sitting in the new location.
One way way to know what changes from day to day is Time Machine, so for your peace of mind, set that up and now you’ll have a reliable measure to track files even if they move / delete and even better - you’ll have a backup and not just a record of what was lost or misplaced.


iTunes do not connect to iTunes Store anymore

I found the solution here

  Try this folks - it has just solved my problem - iTunes 10.5 is
  running perfectly and only using about 50% CPU.

  Start --> Programs --> Accessories (Right Click on Command Prompt) -->
  Run as Administrator then type in: Netsh winsock reset Hit enter,
  restart PC, open iTunes, go to Store

  Alternatively you can use the 'Run' icon just to the right of 'All
  Programs' when you click on start, past in Netsh winsock reset and
  enter.

  Hopefully it works for you too.

  For further reference material on this have a look at:

Blink / fade out to where the text-cursor is - Effect?

I don't know of a program that works system-wide, but if you use the terminal moderately, iterm2 has this feature. Pressing Command-/ once will show the cursor with some screen fade, and pressing and holding it will white out everything on screen but the cursor.

Alternatively, not the same as fading, but there might be a way to have your text editor highlight vertical and horizontal columns. (Here's a plugin for sublime).


Is there a setting for black and white printing from iOS?

There doesn't seem to be a way to do this natively.

Your options seem to be:

Get a black-and-white airprint printer.
Use a black-and-white, non-airprint printer with AirPrint Activator.
Use Epson's app which seems to let you print black-and-white photos.
Use HP's app which seems to let you choose these kind of settings.
Tell Apple you want this feature.


Strange loading screen when MBP battery dies and reboots

This feature is called Safe Sleep. Apple notebooks will keep the RAM contents alive (sleep in PC jargon), but write a copy to the disk (hibernate, in PC jargon) at the same time.

If the battery runs out while the computer is sleeping, when it wakes up, it needs to read the RAM contents from disk, and thus you get the progress bar you are seeing.

Apple doc about it is here


Are there any performance limitations when running a VM of a Boot Camp installation?

As I use it on regular basis I can say it's good performance of using Bootcamp installed windows via VMWare Fusion 3.

Here is process I followed.

Make a bootcamp partition using Bootcamp Assistant for the space.
Install the Windows XP version.
Open the VMware and select the bootcamp partition, when you create a new virtual machine for Windows.
VMWare installs few utilities on the bootcamp partition, to use it to boot via Fusion.
Once all this is done, you can launch this windows version like a normal virtual machine in Fusion.

If I want a lite usage of windows I will boot via Fusion, if I want to run heavy programs then I will boot into Bootcamp, but I rarely does it, as Fusion VM is 99% OK for me for all activities including development with Eclipse.


Filename and editing permissions are gone from Finder Tags

I restarted the mds service and the problem was fixed. I also re-indexed my hard drive.


Using MacBook Pro's monitor for Windows PC

You can't physically connect your Windows PC to your MBP so just using the monitor is not possible. You can use any of the various screen sharing solutions out there to access your PC from your Mac:

TeamViewer is kind of straightforward to setup on both machines
TighVNC Server can be installed on the Windows side and connected to from your Mac by typing Cmd-K in Finder and entering vnc://name-of-windows-pc as an address


How do I make my iPod 5 gen stop asking for my Apple ID password to update an app?

Agree with @Tyson, updates do not require a password in recent versions of iOS, presuming you are signed into the App Store with the account that originally purchased (or acquired) the app.

If you have multiple accounts, and each account has downloaded one or more apps, you are always going to be prompted for the password if the account that is signed in is not the same one as the account that purchased the app that you are trying to update.

It sounds like in your case you might have changed Apple IDs, or used somebody else's when originally acquiring the apps? In which case, you can sign out of the store (App Store > first tab > "Sign Out [your email]" at the bottom) and sign back in with the account that acquired the apps you are trying to update.


My iPhone storage space is never released

Open the Settings App on your iPhone, go to Photos & Camera.

Under the mentioned menu, you will see 2 options: Optimize iPhone Storage and Download and Keep Originals.

If Download and Keep Originals is selected, this is the cause of your issue.
Choose Optimize iPhone Storage. (Be sure that your Photos are Synced/Backed up on iCloud or on your PC or Mac - This option should not delete any photos from iCloud, but just to be safe).

Hope my answer solves your issue. I checked the settings on my iPhone 6s 64gb.


Strategy for storage on Mac Pro with SSD

I have been building out Mac Pros for a while with SSD for the boot, user accounts and all the apps that fit.

Placing the large user data that doesn't fit as well as large Apps on the magnetic storage has worked well as the system and user caches stay on the SSD. You absolutely want your code and build scratch / temp files / object files on SSD for speed reasons.

The simpler the better - I have been using software RAID to span the HDD so the users all see three volumes whether or not they have one drive partitioned, a mix of SSD/HDD or full SSD/HDD and external drives for data and/or TimeMachine.

Macintosh HD - SSD unless lower performance is OK.
Data - all the HDD striped (optional on non SSD macs)
Time Machine - internal if possible - external

On the fastest macs - we are thinking of striping 3 SSD as DATA - moving the Time Machine to external storage as buying large (teraByte) SSD is still a costly proposition.


How to boost microphone input volume above 100%?

To increase the sound, import the sound file into an iMovie project. Once it is in, select the audio recording and drag the volume slider to anything beyond 100% (you can also click the sound button in the app and increase it from there).
Once you're done modifying the volume, share the iMovie project as an audio file.


iPad Pro 11" keyboard case stops working when screen is laid flat against the back sleeve

The previous generation 10.5" has this same limitation. There is a magnetic switch in the bottom edge that prevents the keyboard from activating if it's not in one of the slots on the keyboard case - simply having the connection to the iPad is not sufficient.


You can't turn off SIP on a running macOS system. You need to boot into the Recovery partition and run the csrutil command. This page at Macworld details the steps nicely.

Restart your Mac.

Before OS X starts up, hold down Command-R and keep it held down until you see an Apple icon and a progress bar. Release. This boots you into Recovery.

From the Utilities menu, select Terminal. At the prompt type exactly the following and then press Return: csrutil disable

Terminal should display a message that SIP was disabled.

From the  menu, select Restart.

You can re-enable SIP by following the above steps, but using csrutil enable instead.


i had exactly the same issue. Cleaned the charging socket + the earphone entrance.  Voila!  it was working again


You may want to reinstall it and use "AppCleaner" to properly remove it and all of its remnants.


Unicode character U+273F rendered as a cherry blossom in browser but not in applications

You need to switch to a font used for Chinese, Japanese, or Korean to get that form of the 273F character.  Check the Font Variation pane in Character Viewer for that unicode value to see which ones on your machine will do it.


Erase old iPhone - forgotten restrictions passcode and no WiFi

Will an iPhone/iPod Touch charge faster when connected to USB 3.0?

I have tested an iPhone 5, and on my system it charges from a USB 3.0 port at the same rate as a 500 mA USB 2.0 port. As you would expect, the included 1 A wall charger is about twice as fast.


LDAP user VNC screen sharing suddenly broke. Other LDAP users work, local admin works

The LDAP user had changed their password, but their login keychain on this box still needed to be updated. Apparently, you can't log in via VNC if your login.keychain password and your account password don't match.

I discovered this when I VNCed in as a different user, then logged out, and then tried to log in as the affected user. I was able to log in, but then I received a prompt saying:

  The system was unable to unlock your login keychain.

I chose Update Keychain Password, and entered the old LDAP password, and everything worked!


The iPhone "xyz" could not be updated. An unknown error occurred (4000)

Just update your iPhone using your iPhone update function, not the one offered in iTunes.
I have overseen another possible solution in the link of the question:

"Finally just put iPhone into Recovery Mode and did an update.
SUCCESS.  It did the 12.4.1 update and all seems fine."

Probably that would have helped as well. But the easiest solution is just to update your iPhone as you would do anyway if you did not have iTunes.


There are several 3rd-party “un-installers” available for Mac. The one I use is AppZapper.

There may be files in "~/Library/Application Support/{folder name of app}" and there may be a preference file in ~/Library/Preferences/.

Sandboxed apps have their data in "~/Library/Containers/{folder name of company}"

Some applications may also install more complicated things like kexts. Most of those apps will have their own uninstallers.


I gave up trying to fix this directly, but after upgrading to macOS 11, and using the same SSD freshly formatted with APFS - as now supported in macOS 11 - TimeMachine is back to working as it should, with hourly snapshots being cleared out after 24hrs.
I can't say if the upgrade cleared out something corrupted, or if macOS 11 can now deal with the issue I was having, but it did fix things.


As fsb mentions, the photos are all tied with the Apple Id which is associated with the iPad. So, here is what we did

Connect iPad to PC / Mac
Copy all of the photos from iPad to PC / Mac
Upload photos to Google Photos associated with Dad's gmail
In the new iPad, sign in with Dad's email address (this can be the same gmail account as above or a new account).
Download the Google Photos app and sign into it with the gmail mentioned in step 3.


Well, the Mac Pro went through quite a long period of stagnancy recently, which is likely the cause of the disparity you see between the iMac and Mac Pro in terms of software compatibility.

According to the MacRumors Buyer's Guide, the Mac Pro has by far the largest average time between refreshes (449 days), so new models are sparse.

Because of that, it's a good time to buy, if that's what you're asking. Though there could be a minor spec bump or price drop at any time (those are more or less unpredictable from afar), it's not worth the risk of waiting for one. The December 2013 update is likely the only major refresh we'll see for quite a while.

As far as average lifetime goes, the Early 2008 Mac Pro shipped with OS X Leopard (10.5), and is still supported in Yosemite (10.10), so it has received five software updates so far (and there could still be more).

Based on that, you could expect software compatibility to last for upwards of 6 years on a Mac Pro bought today, if that's how you define lifetime. However, the Mac will of course function on old software for much longer than that.


How do I prepare a new device in Configurator without updating the device iOS?

Place the required version iOS ipsw file here:

~/Library/Containers/com.apple.configurator/Data/Library/Caches/com.apple.configurator/Firmware/

Use the Edit Custom iOS Versions command
In Apple Configurator, hold down the Option key while choosing Devices > Edit Custom iOS Versions. You can then add or remove custom versions of iOS software, such as developer previews.

Can't Install Any Mac OS on Core 2 Duo Macbook

You don't specify the exact model of Core 2 Duo MacBook you're using, so the first thing to try is see if you can actually boot into macOS Recovery over the Internet, as some models were able to have their firmware updated to do just that.

First you need to be somewhere where you will be able to access the internet - however this works best with Wi-Fi networks using WEP and WPA security

Follow these steps:

Ensure your MacBook is fully powered off
Hold down the CommandOptionR keys and press the Power button
Keep holding down the keys until you see a spinning globe with the message Starting Internet Recovery
Soon you’ll see a progress bar - be patient as this may take a while
Eventually the Utilities screen will appear
Choose the Reinstall option
Follow the prompts

If your MacBook is not compatible with Internet Recovery let me know and we’ll go to plan B.

Prevent MacBook Pro from turning on by touching trackpad

Same situation here - shut down the MacBook 2018, then wait a few minutes, touch trackpad or any of the buttons and it starts booting up. Very annoying.

Found the answer here Turn on (start up) your Mac Looks like it's the expected behavior. From their support page:

  Additionally, MacBook Pro (2018) and MacBook Air (Retina, 13-inch, 2018) turn on when you press any key on the keyboard or press the trackpad.

Which is exactly my case.


Plugging it in to iTunes again and re-restoring it did the trick.


SSD in enclosure does not mount on older MacBook Pro

The answer is, make sure that your SSD has adequate power.

Some USB cables come with two USB plugs at one end.

The second and thinner part of the cable is needed for power supply.

So plug in both ends one in each USB port of the computer and then it should supply enough power.

Alternatively, and this made for a more reliable power supply, one can use any USB device that supplies power. In this case an iPhone charger attached to the second USB end (power-only) did the trick.


In Finder, go to the highest level available by repeatedly pressing Command-Up, or by right clicking the current folder name in the title bar and selecting the bottom entry.

From this location (called "Arnoud's Macbook Pro" or something), you should see a folder called "Network." This will show you a variety of network shares.

To see every device advertising itself on the network, check out Bonjour Browser, which will display all registered zeroconf devices.


Assign Application Windows to Different Spaces/Desktops

You might make a copy of Safari's application bundle and change the bundle identifier:

cp -R /Applications/Safari.app /Applications/Safari2.app
defaults write /Applications/Safari2.app/Contents/Info.plist CFBundleIdentifier my.safari2
cp ~/Library/Preferences/com.apple.Safari.plist ~/Library/Preferences/my.safari2.plist

Assignments to spaces are per bundle identifier:

$ defaults read ~/Library/Preferences/com.apple.spaces.plist app-bindings
{
    "my.safari2" = "FC886111-EE78-4844-A5E5-A11BECA713CF";
}

In this case, you might also use Webkit.app or create a site-specific browser with Fluid.


Not able to login using network account after upgrade to High Sierra

You will still need local and Active Directory administrator account for this to work, but here's the exact steps I took to fix this issue.

Login with local administrator account
Go to System Preferences > Users & Groups
Press Login Options > Unlock > Press Edit near Network Account Server > Open Directory Utility > Unlock > Select Active Directory and press "Edit settings for the selected service" button at the bottom > Unbind > Enter Active Directory administrator credentials and finish the unbinding process
Close Directory Utility and reboot the computer
Repeat steps 1 and 2
Press Join near Network Account Server
Enter your domain (ad.example.com) and Active Directory administrator credentials.

Assuming your AD account is not entirely network account (created on your local system and you can use it without network access) you should also set settings in 8-10 steps.

Optional Step - Go to System Preferences > Users & Groups
Optional Step - Login Options > Unlock > Press Edit on Network Account Server > Open Directory Utility > Unlock > Select Active Directory and press "Edit settings for the selected service" button at the bottom
Optional Step - Press Show more > Check "Create mobile login at login" > Uncheck "Require confirmation before creating a mobile account"
Log out (may need another reboot)
Login with network account by selecting the user from the list or using your name on password (depends on "Display login windows as" setting)


Modifing a preference via applescript changes file group

In short, it doesn't matter.

ls -l print out consists of status (10 character), number of links, owner, group, etc.

Of the first 10 characters describe file type(1), owner permission(3), group permission, and permission for others. In the case of

 -rw-r--r--  1 root  wheel

File type: - means regular file.

Owner Permission: rw- means user root can read and write.

Group Permission: r-- means user(s) in group wheel can read only.

Others: r-- means user(s) not in group wheel can also read only.

So you don't have to read the rest to know there is not security risk for what the group is.

So what are the users in wheel, admin and staff?

$dscacheutil -q group -a name wheel; dscacheutil -q group -a name staff; dscacheutil -q group -a name admin

You get:

name: wheel
password: *
gid: 0
users: root

name: staff
password: *
gid: 20
users: root

name: admin
password: *
gid: 80
users: root YourUserNameHere

wheel is a legacy thing from UNIX. OS X never bothered to change it. When you sudo the file, sudo automatically use group staff. If you don't want the group name to change on the file, do:

sudo -g wheel defaults write /Library/Preferences/com.apple.alf globalstate -int 2

Full screen always enabled when opening app in OS X

There's an option called resume I think - check out this post. https://discussions.apple.com/thread/4140495?tstart=0.  To quote the answer, you can do

  System Preferences > General > Uncheck 'Close windows when quitting an
  application'

Not exactly what you want, but it's a possible alternative maybe?


Does AirPlay online stream to Apple TV still go through the iPad?

If you stream a video from the internet, and then AirPlay is to a suitable receiver like an Apple TV, then all the devices in the chain still take part.  The Apple TV doesn't simply get the stream location and other data like playback location, then stream it by itself, it get's a secondary copy that the iPad is essentially repeating onwards.

You can easily test this by streaming something, then airplaying it to the AppleTV, then turning airplane mode on the iPad - the Apple TV stream should fail.

It should resume right away wen the internet is back online! This happened to me and it just resumed right away! If your worried about it, go to a public place and do the restore! It should only take about 10-15 minutes!


Battery jumps from 25% to 2% to 36%. What's going on?

I have a 2012 MBA as well.

The battery is still doing it, at 510 cycles now.

In your case try the SMC reset to fix that problem.

If you hold the "alt" key then click on the battery, it will give you some information including what is consuming it.

If you open the Activity Monitor in your Utility folder, then click on the Energy tab, there will be a display of Battery performance for the last 12 hours:


You enable Data Roaming when showing the green part to the left.

On iOS 6 and older you had the text ON or OFF on the button. OFF disabled Data Roaming, and ON enabled Data Roaming and the button was showing a blue background behind the ON. So on iOS 7 you have the same behavior - just without the ON/OFF text, and with a green background - you can however turn on an 1 as ON and a 0 as OFF under Settings=>General=>Accessibility=>On/Off Labels)


Why hasn't XNU kernel been extensively used?

On one hand, Linux had a considerable head start on XNU, having been first released in 1991. While I can't seem to find information on a release date for XNU, I'm quite sure it happened after Apple acquired NeXT, in 1997.

Also, the kernel design used in XNU may not be easy for some developers to get their head around. Linux is a monolithic kernel, while XNU is a hybrid (a cross between monolithic and micro kernel models) It's possible that developers are more comfortable developing for the former model than the latter. Ken Thompson, one of the fathers of UNIX, also argued this point.

More information can be found on Wikipedia (starting at Kernel)


Taking long list of repeated values and copying to sorted, unique list

This AppleScript uses terms from the AppleScript Toolbox plug-in to function correctly.

I copied your list of duplicates and pasted them between the double quotes in the first line of my code

How to tell if iTunes in the mini player mode from applescript

You can do something like that :

tell application "System Events"
    tell process "iTunes"
        if title of window 1 is "MiniPlayer" then
            -- If mini player
        else if title of window 1 is not "MiniPlayer" then
            -- if big player
        end if
    end tell
end tell


Python IDLE can't be opened by double-clicking .py files in Finder

You can right-click on a python file and select get info. Near the bottom of the get info window is a section that reads Open With. You can select a version of Idle to use. There is a button below that reads change all. If you click this, then all files with .py extension will be opened with idle. Just tested this and it works.  Below is an image indicating the relevant points.


In most cases this is my experience that the type setting of an electronic text contains fewer words and images than a physical book.

Have you spot checked a few chapters in the middle and then the last page to be sure your book has what you expect?


I could fix the problem by reloading the kernel extension for audio with these command:

sudo kextunload /System/Library/Extensions/AppleHDA.kext
sudo kextload /System/Library/Extensions/AppleHDA.kext


Use find to locate files like this way:

find . -name "* 2" -exec rm -r "{}" \;

This command will search for files and folders from where your are . with name "* 2" and delete every result -exec rm {}.

If you want to rename directories:

find . -name "* 2" -type d -exec rename 's/ 2/-copy/g' {} \;

As other command, locate only folders with name "*.2" and rename it replacing 2 with -copy.

If you don't have rename installed, you can also use

find . -name "* 2" -type d -exec bash -c '[[ -x "${0/ 2/-copy}" ]] || mv "$0" "${0/ 2/-copy}"' {} \;

(The [[ -x part tests whether a file/folder already exists).


Is there a way to customize highlight colors in Preview (Mountain Lion and later)?

What they are talking about is having more color choices for highlighting text than are available by default. Both the Yosemite choices in your post and the Mavericks choices (see below) limit the user to 5 preset colors. There doesn't appear to be any way to use the OS-built-in Apple color picker to choose anything other than this very limited set. Very frustrating.


How to know that a macbook pro box has never been opened ?

MacBook, MacBook Air & MacBook Pro boxes are sealed with shrink wrap. Inside, the machine has a clear plastic sleeve with an Apple license sticker which has a perforated strip which is intended to be broken. However you can open this sleeve from the side leaving the sticker intact.


Pages keeps deleting empty lines when I change the font style

Why can't I drag columns in Finder's Column View?

This happens when that separator needs to accomodate space for a scroll bar due to content length. You can resize them with the handles at the bottom end since 10.0.


Macbook 13 pro 2019, trying to connect 2 monitors

Judging from the manual, the adaptor can only output the same video signal to the different connectors at once. This means you can extend your screen once, but not multiple times. Most likely, the Mac does not even see that multiple monitors are connected, instead the adaptor just mirrors the one incoming video signal to multiple video outputs.
To extend your screen multiple times, you would need to get another adaptor or a powered hub.
EDIT:
As mentioned by @MacGuffin in the comments the manual mentions that this actually is possible under Windows, yet it doesn't show that under macOS. However, trying it with a second HDMI cable instead of the VGA may yield results, although the manual mentions that it should not make a difference - aside from quality.
Since the manual isn't that detailed, I would just try to contact the customer support mentioned at the bottom. They will be able to tell if and how it is possible to connect multiple monitors with different video outputs on macOS.

As a general note: While USB-C offers great bandwidth and speed it is still limited at some point. Plugging in 3 USB-devices, two monitors, 1GB Ethernet and Audio may work, but for sure not at maximum speed. It is not only a USB-C limitation, but also the controller in the HUB/adaptor needs to be able to handle all of that.
For testing drive speed I can recommend BlackMagic Disk Speed Test.


Prevent iTunes from showing video preview frames

There isn't a setting to force iTunes to do this.

This actually depends on the the podcast creator and how they embed the album art into their video files.  So, if you aren't getting album art displayed, the issue is on the creator's end and not on yours.

Yes, there's always a possibility that a laptop has been hacked. Are the observations you have cause for concern - not really.

macOS contains a feature named "Power Nap" which allows the Mac to wake itself up from sleep to perform routine activities for a short while, and then go back to sleep. This is stuff like receiving new emails, syncing calendars and iCloud documents - or when connected to a charger - downloading software updates, taking backups, etc.

You can read about the feature here:

https://support.apple.com/en-bn/HT204032

Regarding SSH remote host identification changed: You'll need to contact the owner/administrator of that host to confirm whether or not the remote host identification change is a problem or not. It can happen for completely benign reasons such as reinstalling the computer, changing SSH configurations, etc.

In addition, it doesn't mean that your computer has been hacked. Rather it means that someone could be tampering with the remote computer or the network in between.

Dictionary is showing strange characters when "US English (IPA)" is selected

I also see |"br{k@t| when viewing bracket with US English IPA on a local Snow Leopard installation.

But, it is not a problem displaying the IPA characters themselves. Other words that shared those mis-transcribed vowel sounds are displayed correctly:

bracket |"br{k@t|
brackish |ˈbrækɪʃ|
bran |bræn|
kit |kɪt|

My guess it that there is just an error in the US English IPA transcription for bracket.

What is the name of the long cable/plug attachment on the MacBook MagSafe charger?

The cable in question (pun intended) is called Power Adapter Extension Cable.

  Overview

  The 1.8-meter Power Adapter Extension Cable is an AC extension cord that provides extra length for your Apple power adapter. Use it with MagSafe and MagSafe 2 power adapters, 10W and 12W USB-A power adapters, and 29W, 30W, 61W, and 96W USB-C power adapters.

P.S.: The attached image is for illustration purpose and is obtained from the aforementioned hyperlink from the Apple Online Store.

Opening an attached pdf file on wiki page outside of browser

I don't think you can open them in Preview without downloading them.  Also - by merely opening or viewing the document at all, you are actually downloading it.  It's stored in a temp directory somewhere, and likely trashed when you close your browser.


Open Settings, then tap on iCloud (where your name appears, above the option for Airplane Mode) and try signing back into your account.

How can I easily and individually update the Genre tag for a lot of songs?

As a quick-fix you might just add the "Genre" field to the list of displayed columns (Cmd-J or right-click any column name) and edit the value there directly (double-click on the current value):

There are also applications available who try to clean song metadata automatically (e.g. Tagalicious) but they only work for "well-known" tracks and will probably not tag the genre the way you need it.

Can you add an external fingerprint reader to a MacBook that will work like the built-in reader?

No, there's no external fingerprint reader that works like the built-in reader. The built-in reader is not communicating directly with macOS on the main CPU, instead it communicates with a seperate kernel (still Darwin) running on a secondary ARM CPU.

As there's no way to connect an external fingerprint reader to the secondary ARM CPU, it is simply not possible for 3rd parties to create something that works exactly like the built-in reader and offers the same functionality.


You can use a 3rd party browser to access icloud.com without being redirected to https://www.icloud.com/iphone_welcome. But beware, as you will see, icloud.com is not designed for a small display size like the iPhone's.

The key to accessing icloud.com is that the web browser doesn't identify itself as Safari Mobile.

Many browsers I tried, including Opera, Mercury and vBrowse, didn't work. I could finally find one which offered exactly this functionality: the full version of Atomic Web (note: I'm not affiliated with Atomic Web in any way) lets you set the browser identity to Firefox, Internet Explorer or Safari Desktop.

I chose Firefox 15 and could successfully load icloud.com. However, I soon noticed how uncomfortable it is to browse icloud.com from an iPhone.

To begin with, I couldn't sign in. I pinched and swiped but the display's contents didn't zoom out nor scroll. This is what I saw:

I had to switch to full screen to be able to partially see the Apple ID field:

I tapped on the Apple ID field, the metallic iCloud sign-in window gained focus and could log in.

As I feared, only the left top area of icloud.com's main page was displayed. Luckily, Mail's icon was visible and I could start it:

It was a frustrating experience. I changed orientation several times because, as before, I couldn't reliably scroll. My happiness faded and eventually, tired of trying, I gave up.

I tried Safari Desktop, the WAP browser and IE, but same result (or worse).

So there is a good reason why icloud.com redirects you to use the iPhone apps: icloud.com is not designed to be used with such a small display.

If you really need to have access to iCloud's webmail do yourself a favor and consider getting a tablet. If it's an iPad, install something like Atomic Web. If it isn't, you will be able to access it using the device's default browser.


Is there a Siri command for "Get directions to my next event?"

This is impossible to do as of iOS 10.3.3. About the closest thing you can do is, "Hey Siri where is my next appointment", but there is no way to get directions from the address it spits out.

What I'd recommend, instead of using Siri, is to create a widget in Workflow that will automatically grab the next event's location and give you directions. Note: I have never used Workflow to do this myself but I'm 99% sure it has all the various actions you would need to write a workflow to give you directions with one click.

Sorry you are unable to use Siri in this way and hopefully Workflow will accomplish what you're looking to do.


In iOS 9, where is the "Usage" function in Settings?

It has moved to a little different location. To access the same screen, go to: Settings > General > Storage & iCloud Usage > Manage Storage

Moreover, iOS9 now has a search function inside "Settings". A user can search for a term, such as "Usage" in the search bar to access the corresponding settings.

Have any organizations moved their work Apple ID to two-step authentication?

I will say that I have seen two small organizations do this, but the overhead of setting up the escrow of recovery keys took more effort than we are likely to save in three years of supporting the accounts.

the actual setup went smoothly
people seemed comfortable with mixing work and personal accounts despite the added confusion that it can cause
we didn't run into any roadblocks registering common trusted devices.

Also, now that Volume Purchase Plan redemptions can be reclaimed and they are not lost when issuing expensive apps to personal Apple ID, the need to more tightly control which Apple ID is used to redeem a purchase is not nearly as valuable as it would have been in the cases where we looked at implementing this.

The strategy we are now taking is to just establish a written policy that work apps are to be returned to work - just like work computers and work phones and have employees sign for the tools they are provided with an HR policy to deduct value for tools not properly returned at the end of employment.

Your MacBook Pro model came with either an AMD Radeon HD 6490M or 6750M and Intel HD Graphics 3000 as its graphics card options.

While your MBP does support up to two Thunderbolt displays in the following modes: dual display extended and video mirroring, it's only capable of an external resolution of up to 2560x1600 pixels.

Unfortunately, this resolution output falls below 4K resolution which is basically in the order of 4000x2000 pixels.

However, the maximum resolution of your 15.4" built in display is 1680x1050 pixels, so while you can't output 4K resolution to an  external display, the 2560x1600 pixels you can output is still an improvement.


I think it's unlikely that your total electricity bill went up significantly because of this. A battery is just an "energy container": the energy it contains came from your wall socket.

If the battery won't hold charge, then the Mac is just using the electricity it needs to run.

If the battery will hold charge, then the Mac is using the electricity it needs to run PLUS refilling the battery. You can of course use the Mac on battery, but then you're recouping the extra you used to fill it.

Let's say your Mac needs 10W to run, and 20W to fill the battery over 2.5 hours. You normally use it for 5 hours a day. With 'no' battery: you use 10W to run it, for 5 hours: 50Wh per day.

With a working battery, you charge up the laptop (while it's off) at 20W for 2.5 hours (50Wh), and then use that charge over 5 hours or so.

Or, you could use it on power for 5 hours, while charging the battery: 30W (running and charging) for 2.5 hours plus 10W (running) for 2.5 hours. That's 100Wh, but now you've got a full battery, which will see you through tomorrow.

TL;DR: Assuming you're spending the same time on your Mac, your energy usage should not change much. But it's worth getting the battery replaced anyway.


Highlight sentence feature with text-to-speech

I believe that this is among the features of Kurzweil reader. They offer a free trial, so you can see whether this is what you'd like.

Another solution is Apple's own VoiceOver, which is built into the system. See especially the chapter on Working With Text.


Picture-In-Picture (PIP) feature in Apple TV 4K (5th gen)

No, there no such feature on the Apple TV 4K (or any other AppleTV product).

An app can implement PiP within the app (such as for example the ESPN app's MultiCast feature), but that is just within one app.

PiP between two apps is not yet possible on the Apple TV.


There are two possibilities.

Broken SIM card. This would be more likely because SIM cards are small and break easily. However, you mentioned that the SIM card works ok in other phones. I would still suggest getting a replacement SIM card, as that will be easier than the other possibility.
Problematic phone. It is possible that the problem is with the phone itself. It could be a hardware problem, a firmware problem, or a software problem. The only way to tell would be to take the phone to an Apple Store (or, if that's not possible, an Apple Authorized Service Provider) to get it checked out.


I have an iPhone and 2 non apple computers with iTunes. I want 2 Apple IDs on my phone and the content off 1 computer backed up on another.

Thank you for posting today. I'm sure we can find a workable solution for you today.

Apple allows multiple computers to hold and play content, sync to devices, and all of that via iTunes. For you to play the content from the older computer on the newer one, here is what you will have to do:

Copy over the content from the iTunes Media folder on Computer A (old computer) to the iTunes Media on Computer B (new computer). Typically, the iTunes Media folder is located under C:\Users{your user}\My Music\iTunes\iTunes Media. (See special note on Step 2)
Import the music and all other files to your newer iTunes library. The easiest way to do this, if you want all content, is simply to place all of the files when copying them over into the "Add to iTunes" folder located within the iTunes Media folder.
When the item is in the new iTunes on Computer B, try playing one of the files. You will be prompted to authorize your computer for your dad's account.
Sign-in to your Dad's iTunes account to authorize. This can be done on up to 5 computers, including the original, and can be modified at a later time via iTunes Store -> My Account -> Authorized Devices
You should now be able to sync as needed with your iDevice and others

Please note that if you had apps under the older account and sync those to your phone, if they need to be updated it will require the other login (though this is about to be phased out). Music, however, should load without issue as long as the computer that you synced with retains authorization to play. The iPhone won't care which AppleID bought it, as long as it is able to make it onto the device (either by purchase on the iPhone or by purchase/authorization/etc on the computer and synced up).

Hope this helps!


There is an option in Settings > Mail, Contacts, Calendars

You can set it to only Sync Reminders 2 Weeks Back

That's the lowest value you can set.


Where can I find replacement feet for my MacBook Pro?

I had an old Powerbook G3 that had lost 2 of it's rubber feet. Instead of trying to replace them with the same ones, I just went to a hardware store and bought the little rubber stick-on feet that you could put on the bottom of furniture or a TV stand or whatever. Cost all of about 99 cents and worked perfectly.

They looked something like this:


What encryption method was used in OS9 Apple File Security?

I don't know what the format is, but my understanding is that ye olde Finder uses extended attributes to determine if the file has been encrypted. You could probably manually add this data back and get it to recognize it is encrypted again.

For example, here are the extended attributes on a file I created in OS 9:

$ xattr -l helloworld.txt
com.apple.FinderInfo:
00000000  65 6E 63 32 63 72 70 32 01 00 00 00 00 00 00 00  |enc2crp2........|
00000010  00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00  |................|
00000020

Contents of the file before encryption:

$ xxd helloworld.txt
00000000: 6865 6c6c 6f20 776f 726c 64              hello world

This Terminal command can add the attribute back to the file:

xattr -w -x 'com.apple.FinderInfo' '65 6E 63 32 63 72 70 32 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00' yourfile.ext

Not sure if these commands can be done from OS 9 but you should be able to do it from a modern macOS system and then pack the file in a .hqx file with binhex encode yourfile.ext for safe transport (so the attributes are not lost).


Unable to launch photos library repair tool in macOS high sierra?

I had same issue, this worked for me:

After it opens, close down photos and retry double clicking  photos icon holding down with the option & command keys held down.


Desktop wallpaper changes only apparently

I had problems with my desktop wallpaper after uninstalling Kuvva as well. In my case, removing the desktop plist file solved the problem.

To do this, run the following command from the terminal:

Then log out and log back in. Be aware that this will also return any other desktop settings to their defaults. If you're uneasy about just outright deleting this plist, you can always make a backup copy first.


Have the snooze buttons on the iPhone changed?

It looks like this has been around for a while.

I found an iOS 10 user complaining that the Home Button shut off the alarm:

  turning on the phone (pressing the home button) shuts off the alarm!

(Source)

I also found several articles form a while back explaining you can use the Home Button to stop your alarm.

Just tested and the Home Button also stops it for me.

It could possibly be you thought you pressed another button that you didn’t, or maybe you were using another app or jailbreak tweak.


Is something missing from my Macbook Air package?

No. The mid 2011 air uses Internet recovery to network boot and reinstall lion.

You can use the recovery hd assistant to make your own USB media for booting if you don't expect to have Internet when you ever need to restore your air.


Temperature different of adapter since Mountain Lion (maybe only rMBP related)

That's interesting, I a have been running a non-Retina i7 for over a year, Lion OSX, and have found that CPU and GPU get drastically throttled as MagSafe-1 gets hotter and hotter. Nothing unusual I guess but I didn't expect it to impact the performance of the machine.
I may just upgrade to Mountain Lion, hopefully that will fix the throttling!


My Mac Mini 2014 has an Intel Iris Pro graphics. Upgrading from Yosemite to El Capitan definitly improved the overall smoothness. Resizing Finder windows is buttery smooth, for example. Switching the preference panes is just as smooth as it was on Mavericks.
It's noticable in about all applications. El Capitan is definitly an improvement.


Edit
As pointed out by Kent, an iMac with a 2.16 Ghz Intel 2 Duo seems to be like an iMac (Late 2006) instead of an iMac (Mid 2007).
Technical Specs for iMac (Late 2006)
Technical Specs for iMac (Late 2007)
Therefore, you can only run Lion. Unfortunately, finding a legitimate copy of Lion could be a little tricky if you haven’t already purchased it. If you search for OS X Lion in the Mac App Store you’ll only find Mountain Lion, and Apple no longer sells an OS X Lion USB Thumb Drive (part number MD256Z/A) in its online store.
One of your options is to buy from Amazon or another online retailer.
Or, get Snow Leopard.
Original Post
You have to install Snow Leopard first and then Mountain Lion.
OS X Mountain Lion system requirements
To install Mountain Lion, you need one of these Macs:
**iMac (Mid 2007 or newer)** (Yours)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)

Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory
8 GB or more of available space

Your model must have a 64-bit EFI boot ROM.
An easy way to tell if you are running a K64 kernel is to use the uname command-line program. The "x86_64" in the excerpt below means that we are running a 64-bit kernel. If the output showed "i386" instead, that would mean a 32-bit kernel.
uname -a Darwin... root:xnu-1456.1.25~1/RELEASE_X86_64 x86_64

Shortcut for dragging and dropping a tab on terminal

There is no such shortcut in Terminal (apart of dragging the tabs manually), however such feature works fine out-of-box in Term2 by hitting Shift-CMD-←/→.

Another way is to have tabs in separate windows (CMD-N)and switch between them by CMD-1,2,3, etc in order you like.

Does Time Machine backup iCloud Drive files that are not stored locally?

No, these files are not backed up by Time Machine.

iCloud has its own deleted file recovery, available from iCloud.com Settings → Restore Files, but this isn't a substitute for backups since modified files are not stored, only those deleted completely.


How to share keyboard and mouse in Target Display Mode

I solved this issue using a Griffin PowerMate (basically, a USB-wired button) and some AppleScript to switch Bluetooth off on the iMac, freeing up the keyboard and mouse so my MacBook (connected via TDM) could take over.

It's very smooth (as smooth as can be for something non-standard). I just connect my MacBook to the iMac, hit cmd+F2 on the keyboard, then tap the button to disable Bluetooth and let the MacBook take charge. When I'm finished, I just unhook TDM, close the MacBook and tap the button again to reconnect the keyboard and mouse to the iMac's Bluetooth.

Details here - hope it's useful to someone else: http://jamesholland.com/post/80600076762/hacking-mac-os-x-to-toggle-bluetooth-for-better-target


Have a separate password for Game Center

Yes and no :-)

If you use your Apple ID to log into Gamecenter, you must use the same password as for all the other places you use your Apple ID to log in.
You can create a new Apple ID on icloud.com though and use that one for Gamecenter


macbook pro keyboard keys look polished after a few months

All keyboards by any manfacturer have shown wear over time.
We even had keyboards made with stainless steel designed for heavy use and they showed signs of wear.
Fingers carry dirt which abrades the keys and coatings over time - even if you wash your hands prior to use , you pick up something from the desk and back to dirty.
My macbook pro keyboard I have worn through to the clear plastic past the symbols and black base.
Replace the keyboard and put a cover on it but nothing lasts forever. Or use an external keyboard but not practical in all situations.
You are not alone...


Extract a sound from a Classic application for Mac OS X?

I had some System 7 Sound files, too. I just tried DaveM's answer, and it worked, except I had to set the frequency to 11025 (not 8192).

My steps:

Used Rezilla to copy the raw hex from the resource fork.
Used Hex Fiend to paste it as a regular file (added .au extension, but that doesn't really do much since it's still not directly playable)
Audacity > File > Import > Raw Data, select .au file
Change Sample Rate to 11025 Hz
Export as wav!


How can I tell what's being backed up by Time Machine?

The way the backup works is that it does a large base image of EVERYTHING and then each new backup just backs up changes.

However - If you perform a touch command, or you move files or interact with them in anyway, this can cause it to flag as being a change, and it will back it up again.


If you want an app/program I would recommend that you search the Mac App Store and try googling for one.
I've heard that Sunrise Calendar is good but I think you need to find one that works good for you.

Personally, I would pin the Google Calendar website in Safari "Top Sites".


Q: Backing up Notes.app content (on the iCloud / OSX / iOS) for safekeep?

The content of your Notes.app is located in /Users/youUserName/Library/Containers/com.apple.Notes/Data/Library/Notes

So to back it all up you need to copy/move everything in the directory above to another location and restore it later.


One of the recent version update changelogs for Tweetbot states they made a change to the share sheet, which may in turn have caused a bug that is preventing Safari from showing up. This would best be reported to the developer of the app.

In iOS 8.x, a developer basically advertises "I have this type of data to be shared, what apps can share it?" The system responds with a list of apps that are capable of receiving that type of data. (Types can include text, a web URL, images, and so forth.) Depending on what type of data Tweetbot is advertising, it may not be compatible with what Safari says it can receive - Tweetbot might be advertising the URL in plain text format, whereas Safari might only be able to receive the URL specifically formatted as a URL.


How to disable iOS FaceTime notification sounds?

I found this extremely frustrating as well. I spent an hour trying to record a silent ringtone in GarageBand but it consistently delivered noisey ringtones despite no sound on the track. I was about to give up when I thought someone else besides us must have been annoyed and figured it out. A Google search yielded the silent ringtone below. I tried it and it works great. Good luck.

How can I run Warcraft III (a PowerPC app) on OS X Mountain Lion?

Two ideas I can think of.  First, dual boot with OS X 10.6, which still supports Rosetta.

The other is to obtain a copy of Snow Leopard Server, which had a license which allowed you to run it in a virtual machine.  (The license for normal SL did not allow you to run it in a VM.  Lion and Mountain Lion changed the license to allow it.) Then use Parallels or VMWare Fusion to run it.  However, I don't believe the graphic support is very good with guest OS X machines, so it may not run well.

Even if you can find a way to install the app, IIRC Warcraft III was a PPC binary for the game as well, so you'd still be stuck.

What’s going wrong with printing my mini booklet?

Although MacOS doesn't comes with a built-in booklet maker, there are a number of ready-made options to avoid doing this manually.

PDFs can be easily manipulated ("imposed") into booklet spreads, and there are several apps to do this, both on the Mac App Store and on developers' websites. Some are free, some are very cheap.

Adobe Reader contains a booklet setting in its print menu.

You can find a "PDF Service", which will make booklet PDFs and save them to disk here. You will need to install it in your user Library's "PDF Services" folder, which may need creating if not present. Then it will be available in the PDF button of every print dialog. (It's currently set for A3, but there's an option in the script to change the paper size.)

Some Printer drivers have the function built-in, particularly on large-sheet printers.


The short answer is no.

At the moment, most of iPhone 4 hardware is unsupported by iBoot. The thing is that iPhone 4 bootrom hasn't been hacked in order to install custom boot loader that will boot Android and, as I said before, many of iPhone 4 hardware has no drivers.

Also, iDroid allows you to install only 2.x at the moment. However, I have asked the devs some time ago, they told me that they're working on porting Android 4 to the iPhone 4.

Anyway, until there are a needed bootrom hack (which also leads to untethered jailbreak, pod2g/Chronic can release it soon) and quite enough drivers you won't be able to install android on your phone.


Using the extra SATA ports on a 2006 Mac Pro under Bootcamp

You can use those ports once you installed the AHCI drivers. However, you'd still need to boot Windows from a disc connected to one of the drive sleds.

How is the Compressed Mem column in Activity Monitor calculated?

Through various tests on my machine, I have discovered that: The app is using 2.6 GB in addition to the 1GB of compressed memory.

On the Safari Webpage Content processes, if you max out the memory used on your machine, you will see the memory go down as compressed go up. This is how I tested it, and I assume it will work for other apps, but safari usually uses the most memory for me.

Bulk Changing Application Icons on System

@klanomath is close, but you actually can bulk change the icon. While the .icns file is stored within the application, it's referenced in an .xml file known as info.plist inside the Contents folder of every app. There's a string CFBundleIconFile with specifies the name of the .icns file inside the Resources folder.

While simply finding every .icns file and changing it would probably work in most cases, it's not the best practice. While it's rare for .icns files to be used for anything other than application icons, some app bundles include multiple side apps. This method minimizes risk.

If you'd like, I'll gladly assist in building an app to fit your renaming needs.


Cannot SSH into Cisco switch or pfSense router from Mac Mini (macOS High Sierra 10.13.6)

Try this:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 192.168.3.2
ssh -oKexAlgorithms=+diffie-hellman-group-exchange-sha256 192.168.3.1

If I'm reading it right, you've set the cipher for 192.168.3.1 (router) to diffie-hellman-group1-sha1, but it only offers diffie-hellman-group-exchange-sha256 in the DH family.

More info on OpenSSH legacy connections here. Related to that, SHA1 ciphers have been deprecated for good reason - they're considered unsafe or broken, so it would be pertinent to investigate whether your router or switch software can be updated to a modern, more secure version.


What is the new turbo boost in the MacBook line?

Turbo Boost is a feature that, when fewer than the total number of cores are being used, the processor can turn off the unused cores and increase the clock speed on the rest of the cores. This increases performance (the cores that are being used get faster) and can reduce power usage.

For instance, if you have the 2011 MacBook Air with the 1.6 GHz Core i5 (as detailed in this AnandTech article), the "Turbo Ratio" is set to 0047. The number sets the amount of boost by digit (4 cores = 0, 3 cores = 0, 2 cores = 4, 1 core = 7; this is a dual-core CPU, so 3- and 4-core mode is irrelevant). The number specifies the boost in 100 MHz increments above the listed clock speed, so if two cores are running, they can be boosted to 1.6 GHz + 400 MHz = 2.0 GHz and if one core is running, it can be boosted to 1.6 GHz + 700 MHz = 2.3 GHz.

To see what your system is set to, go to Console and open the kernel.log (or system.log in Mountain Lion*), then search for AppleIntelCPUPowerManagement and look for "Turbo Ratios". The Mac I'm on now (a 2.0 GHz Core i7 MacBook Pro), for example, has Turbo Ratios set to 6689 for a maximum clock of 2.9 GHz when using only one core.

PuTTY is a great Windows frontend, not to mention the need for an SSH client in the first place. On Linux, OS X, and most other UNIX-y based environments, SSH is generally purely command line, but still amazingly powerful.

The SSH client allows you to store an amazing amount of properties based on a given hostname, even global defaults, in the "ssh_config" client file. This file doesn't exist by default (per the comments on the question), but should be written at ~/.ssh/config.

That path equates to:
~, your home directory, it expands on my system to /Users/jason.
.ssh, the leading dot makes it hidden. If you're in Terminal and in your home directory, you can simply run cd .ssh and enter it.
config is the file name, it is a plain text file with configuration parameters.

I use this file to control tunnels I always use, the private key needed for the connection, the username (if it differs from my local username), etc.

See the manpage, either via man ssh_config on your own machine which will contain the most appropriate version, or you can view it online from OpenBSD's Site.

Some example contents from my ssh config file are:

ControlMaster auto
ControlPath ~/.ssh/sockets/master-%r-%h-%p
VisualHostKey yes

Host serve
    Hostname 8.8.8.8
    User        jason
    IdentityFile ~/.ssh/id_rsa
    LocalForward 5901 localhost:5901

Whitespace is purely personal preference, it is not required except to separate Keys from Values.

The first three lines are global properties, they affect every SSH connection. The second section is a host-specific configuration.

The Host line specifies the host tag you will use when invoking ssh. Ex. ssh serve. When running that, it loads all the properties listed until the next Host line.

Since serve is not necessarily a DNS name, I specify the Hostname that it should actually connect to (no, not actually mine). User is self explanatory and there just to be explicit, and the IdentityFile is the path to the Private Key file it uses to connect.

Lastly, LocalForward sets up a port forwarding rule that I send through the SSH tunnel.

The various syntaxes are all documented on the man page.

There is no mechanism for defining a plain text password. Password entry is ALWAYS interactive when setting up the SSH connection. If you want to log in automatically, set up Private Key Authentication. Storing plain text passwords is stupid, always.

I use this to great effect. And the best part? All your SSH configurations are incredibly portable, it's just one file that you have to backup/retain, and move between system to system! Not so portable to Windows, but who really likes dealing with the registry anyway?


The proper way to erase bootcamp is use Bootcamp Assistant. Open the Bootcamp Assistant application, choose "Remove Bootcamp Partition", and then follow the steps. This will delete the bootcamp partition and restore your internal drive to a single partition (Macintosh HD).

If you have already erased the contents of the bootcamp partition and are just trying to delete the partition, there is a different set of steps.In this case, open Disk Utility and select "APPLE SSD SD025...". Click on the "Partition" button. Select the triangle in the circle labelled "Bootcamp 37,87 GB". Then click the minus button. This will allow you to erase the partition.


No, it does not.  A goal of iOS is to remove the idea of files and folders and allow the user to focus simply on their data and accessing it whenever they want and wherever they are.

If you need a file manager, you'll need to jailbreak first and then use a myriad of 3rd-party file managers available.


Why does my iPhone display no contacts, but display the correct name when I dial a number?

I had the same problem. Contacts were showing up, for example, if someone called me or sent me a text and were therefore in my 'Recents', but did not show up in my contacts list either through the contacts app or through the phone contacts list itself (probably the same thing anyway!).

The solution that worked for me was to go into iCloud on my iPhone and set Contacts to 'off'.  This gave me the option to 'Keep on my iPhone' or 'Delete from My iPhone'. I chose to delete them. Once this had happened, I re-enabled Contacts and my contacts list was all synchronised back from iCloud correctly within a couple of minutes.

No, it is not possible to install Windows 7 on an iPad Pro. You'll need a desktop/laptop computer to run Windows.

Unlike generally available consumer computers, where you can choose to install supported operating system of your choice, it is not possible to change the operating system on your iPad (or iOS devices in general).

To install Windows, you'll need access to a PC computer. If you do not have access to a PC, Apple's desktop/laptop computers branded as Mac are capable of running Windows both natively or in a virtual machine.


This has nothing to do with your iPhone, or your competence. You received a txt document, in place of the original document, so the original was never sent to you, or rather, it was restricted, by a security tool, from leaving the originators network.

This is very likely a Data Loss Prevention tool (possibly from Trend Micro) that sits on the originator's network, that is preventing the emailing of this document. These tools 'sniff' the contents of an email and attachment, and if they find strings similar to things like social security numbers, membership numbers, or other sensitive corporate data, they will remove the attachment and not allow it to be sent. They also can be set more generically, like not allowing any Excel document to be sent.

You will need to contact the originator, and explain that a security tool on their network is removing the attachment. They will need to ensure that the attachment meets their company's security standards before the system will allow it to be sent.

Trying to install Homebrew, but I get this "fatal: cannot create directory at 'Library/ENV/pkgconfig/10.10': Permission denied"

I would suggest go and visit 'Library/ENV/pkgconfig/10.10', if it's there, try to look at its permission, if it differs, try to delete it and re-run the installation.

It happen to me once also but it's coming from sass/grunt. Permission denied just to find out that special file was created by other user (because I copied it from somewhere) and it have overriding problems, thats why it return permission denied.

Well, that's my case, hope this little stuff might help you. Who knows :P


Anki + Latex not working : I have installed BasicTex + dvipng

I found the answer here Anki+Latex.

Basically you have to download this Anki add-on, which allows you to edit the path Anki uses to find latex and dvipng. Then you use which latex and which dvipng (on Mac terminal) to get the full path to each of them, and then you use the add-on to modify Anki's path.


iPhone does have a shell, bash to be specific, but you can't access the shell without jailbreaking, and any 'shell' app from the App Store won't have the ability to interact with the device in any reasonable manner necessary for fixing network problems.


Safe to Repair NTFS Drive/Partitions When Paragon Is Installed

It is safe to use Disk Utility to add/delete partitions on a drive that is partitioned in MBR or GUID. As long as paragon followed the standards, you won't have any issues.

Do note that NTFS volumes are left alone by Disk Utility so you won't be changing them - just deleting and erasing or working in the free space around them.

How to open numbers spreadsheet in 2 separate windows

Thinking about this some more, I have figured out a workaround. Though it's not altogether satisfactory, it could be useful in some cases. The workaround is iCloud.

Save the Numbers spreadsheet to iCloud drive, and then open it from a web browser. Open a new browser window and again open the spreadsheet from iCloud drive and you now have the spreadsheet open in 2 windows.

You could also have a local copy open in Numbers, with additional windows provided by iCloud browser windows, though there would be some lag between local changes appearing in iCloud and visa versa.

How to format a Time Machine SSD so it can also host the backup for external booting

I ended up verifying this scenario myself, you can restore a Time Machine backup from an SSD partition, onto another APFS partition that's on the same SSD drive
You need to enable booting from external drives on T2 Macbook's, but it's a simple step that you are guided into (Everything available on MacOS Recovery with CMD+R) (You need the root password of the Macbook for Time Machine restore capability and changing the startup security, so if you are going to borrow an actively used device, you either need to get the password too, or do these steps with the owner after they enter the password themselves)
If you try this yourself, the only side effect is the startup disk getting changed to the external drive you just restored a backup onto, the restored OS is regularly usable, the disk benchmarks were 900mb/s read/write when booted from itself (everything kept on working as it was too, the only issue I saw was missing Chrome thumbnails, but Chrome password system was accessible as before)
Overall I think this approach is very practical, obviously you need a secondary time machine since it's risky to use the same ssd that's housing your time machine in case of a secondary failure - It took 35 minutes to restore my ~200GB backup with a 10Gbps nvme enclosure onto itself
Some edge information that's relevant at the moment: Avoid 40Gbps Chinese enclosures, major example is Orico (avoid them like your life depends on it, recently restored a system from an HDD, I had it connected with one of their USB-C/USB-A cables, it turns out the read speeds were 8mb/s because of this faulty cable, while it's 100mb/s if connected with a different cable), I believe they are all manufactured to fail, the enclosures heat SSD drives on idle and have various other issues. I found the Asus ROG Strix Arion 10Gbps drive to be very reliant (seemingly). SSD's don't heat as much (nowhere near 90C, more like 40C) and they are cool when idle. I've tested a Samsung 970 Evo Plus, it was unusable with the 40Gbps thrash enclosure, usable with 10Gbps one, but I wouldn't use it in this scenario, the heat is still concerning. Instead, a WD SN550 Dramless Nvme SSD was both cheaper, cooler and suprisingly faster on average. Since it doesn't throttle due to overheating.


Is Xcode the ideal IDE for most development needs, or is app/web/shell/script development not as narrowly approached?

I have broken down this into several parts:

For Scripting Languages

IDLE... It sucks!
Edit it any one of the text editors (your choice, but i suggest sublime or brackets) and the run in terminal
Use something like pycharm, it is a nice cross between something like xcode and just a text editor

For Programming Languages

For languages like Obj-C, C and C++ you have a couple of options like Codeblocks, Xcode and Eclipse. With Codeblocks, people either hate it or love it (I hate it). Eclipse is versatile but clunky, and Xcode... Xcode I really enjoy it, it is cool, easy-to-use and fun. Probably just starting out, go with Xcode.
For languages like swift, you have not many choices but Xcode.

Comparisons

Scripting Language Editors

Idle: Simple. Limited options and customization.

Sublime Text 2/3: More complex. Tons of extensions and customizations.

Brackets: Simple but complex. tons of themes. Still very new.

Atom: Large app size. Nice looking. Has a sublime-esk.

Programming Language IDE's

Xcode: Easy to use. tons of support. Large community.

Codeblocks: Clunky. * opinion * bad GUI. Has been around for a while.

Eclipse: Versatile, old,large community.

Conclusion

In the end, this question, boils down to opinion. What do you find is good?

For me I use brackets and sublime for scripting, and Xcode for programming.

For you as a beginner, start by looking at sublime text 2 or 3 and Xcode.


How can I recover from failed app update?

This has now happened a couple of more times. I've been able to resolve this the last couple of times by tapping the app back on the main screen (ie not in the app store). The label below it changes to 'Waiting'. Then tapping it again it changes the label to 'Loading' or 'Installing' and the update finally completes. I can then update other apps.

Otherwise the only other solution is to delete and reinstall the app.


Moving photos from Photos app to my iPhone

I would first send the photos on your iPhone back to your Mac using AirDrop. This way you will get ALL iPhone photos on your mac, which you can then import in the Photos app on your Mac. After that you can then sync all photos back to your iPhone with iTunes:

First make a successful backup of your iPhone with iTunes.

Iphone:

Settings -> General -> AirDrop -> Contacts only

Mac:

Open Finder
Click Go in the menu bar and select AirDrop
Allow me to be discoverd by -> Contacts only

Iphone:

Open Photos
Select all photos
Tap the sharing button
Wait untill AirDrop finds your Mac and click it

Mac:

accept the popup window asking you to accept the photos
Import the Photos to the Photos app
Lastly, you can now sync your iPhone with iTunes to transfer all photos/the albums you want to your iPhone. But note that this will erase the media items synced with the previous library (music,podcasts,audiobooks etc.)


simplest way to open all images in a directory in Finder

What Type of SSD is Used in the 2013 Mac Pro?

These particular Mac Pros use an Apple designed PCIe 2.0 x4 interface. If you're wanting to replace the internal drives your options will be limited.

I would check out the following instructions provided by Apple to determine your happy to proceed. If so, I suggest you purchase your SSD from a reputable retailer. For example, the following are some well-regarded sites:

Mac Sales
Simply Mac
RAM City
Macfixit

By buying from a reputable store you'll be sure to get an SSD fit for purpose, regardless of manufacturer. Being reputable means they're only going to sell something that works and they'll stand behind the product they sell, regardless of the brand. I would also check out Amazon as well for particular models once you know what you're after, as you'd probably find you can buy cheaper from there.

Another option

If I was you I would seriously consider keeping your current drive and using an external Thunderbolt enclosure to increase your storage capacity. If speed isn't so important, then you could use external USB drives instead.


Do not delete the download or you will lose the rental.

The only method for transferring rentals is between two devices is when you start by renting it from a computer. This is detailed at the end of a quite large knowledge base article under the section worded Can I play my rental on more than one device?.

  If you download a rented movie on your iPhone 4 or later, iPad, iPod
  touch (4th generation or later), or Apple TV: It is not transferable
  to any other device or computer.

You can get help from Apple to accomplish this move if you are not certain if your software is the correct version or are having difficulties with your account. They might issue a one time refund, but this isn't intended to be something you can regularly do. If you have a TV and an Apple TV, your best alternative might be to AirPlay the movie, but on Lion, you will need third party software like AirServer to get video and music from your iOS device (your phone in this case) to play on the mac. Please research this option well (especially the returns policy before buying), since it says it plays videos and it may not work with protected content like a movie rental.


Photos has migrated the iPhoto library to the Photos library. Photos no longer reads from or writes to the iPhoto library. You only need to back up the Photos library.

Providing you have no referenced masters in the iPhoto library, it's fine to delete. Keep a backup of it for a while in case anything doesn't work. You can copy all your referenced masters into your Photos library by opening your Photos library, navigating to All Photos, selecting all the photos and choosing File → Consolidate…. If you have any referenced masters, this will copy them into the Photos library, such that all the data is contained within the Photos library.


It must have been a bug in the OS that was finally fixed. I just "ignored it" for, well, months... and upon looking at this question today, I decided to look up, and low-and-behold, it's gone.

After months of having to drag it off of the bar, it's now gone for good. Not sure when it left, but it's fixed.


Strange color transitions in dark regions of images

Upon further investigation on color profiles after Agos's comment pointed me in the right direction, it turned out that using the incorrect color profile was responsible for the dither-like regions.

For others who have a similar issue, navigate to System Preferences > Displays > Color and select the profile that the image was exported in.

I would assume that the dithering-like region was due to the colors in that region being out of the color space of sRGB, and as a result the computer attempts to compensate.


It looks like your "BSD process name corresponding to current thread: Google Chrome He" is doing that.

Turn it off and run VLC to verify.

I do not know why, but you can go to the Chromium web site and look for solutions there.


iTunes search API returns different app icons for 60x60 and 1024x1024

Using old iMac, missing parts, as monitor for a PC

27" iMac as old as the late 2009 will support TDM (Target Display Mode), and TDM is available on Snow Leopard, as long as the iMac supports TDM. If your iMac is 27" model, it is more likely to support TDM.

If it doesn't support TDM, there is a DIY method, which requires a lot of hardware modification, including soldering and acquiring appropriate LCD controller so that its built-in monitor can be used as a normal external monitor.  The work involved, the time required, and the cost of parts required for the procedure are often too prohibitive and not worth the effort.  For all that, it's probably better to buy a brand new monitor for less.  I've once tried to convert the beloved iMac G4 for such use, but ultimately failed, although few people have tried and succeeded through extreme measures.  See The 17" iMac G4 to DVI - The Easiest Method Ever (So Far).

Finally, if the iMac is still running, I recommend the software solution. It allows the old iMac to be used as a secondary display to an existing PC or Mac (through VNC and the like).  I've had success with Screen Recycler , which cost around $30, but is well-worth the price.  If it is an older PPC-based iMac and it runs Tiger, I recommend ScreenSpanningDoctor.  Newer software, such as AirDisplay works as well, but it requires Mountain Lion.


0644 is good for pictures. 0755 is only needed for executable files and directories (thanks, Mateusz).

Note that 0644 grants read access to all users. If you want to deny read access to other users, then you might consider 0600 instead.

restarting a airport from the commandline - of a non-mac

You're asking a lot of different stuff here.

Here's the question I am going to try to answer:

"How can I bring my Airport devices into my Nagios monitoring more closely?"

OK so first of all, Nagios supports SNMP and (most?) Airport devices support SNMP.  So "all" you have to do is configure the Airport SNMP settings and then set up Nagios to ingest the data.

Unfortunately the current version of the Apple's Airport Utility (6.3.1) removed the interfaces to the SNMP settings in the Airport.  You can still download the old version (5.6.1) from Apple but the installer for the old version of the Airport Utility refuses to run on Mountain Lion! However it turns out that it is only the installer that is broken in ML!

Some crazy genius has written and made available an Automator workflow that works around this and allows you to install the old version of Airport Utility.  I just tried it and it worked.  Was then able to use it to set the SNMP settings of my Airport devices.

If this ends up working for you and you accept my answer, you should consider rewriting the question so that the question and the answer match.


Shove installed a launch daemon or agent popup window, what is it?

To answer your questions in order....

This does appear to be a BlockBlock dialog box.  A quick look at their webpage shows a similar dialog to the one you've posted.

This warning is telling you that Adobe is attempting to install/update Adobe Flash Player
Do you use Flash Player?  If you do, then yes.  If not, you should investigate what is attempting to install Flash Player (what did you download and open up?)

*On a side note, a more pragmatic question you should be asking yourself is "Why, in 2018, are you still using Adobe Flash?"


Is the waiting for cache message showing up in Google Chrome? If that is the case, then yes, that's a pretty common issue with Chrome itself not specific to OS X. I've had that issue a number of times and have yet to find any way to resolve it apart from a full wipe of the application.

As for the other applications you are talking about, are there some specific applications that freeze, or all apps in general? A screenshot of your Activity Monitor would be ver helpful.


How do you exclude applications from the 'open with' menu

No, they're included automatically by the OS, but if you want to reset the file, you can try this:

Open Terminal in /Applications
Type the following command:
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
Relaunch Finder, click cmd+alt+esc and select Finder and click Relaunch
Now the "Open With..." menu is reseted!


macbook pro 17 2,1 - no video and how to bypass it

Can you boot into Target Disk mode, connect the computer to the network, and use the drive/system remotely..

There are other startup possibilities , and there is also Apple Remote Desktop, and Screen Sharing. Have you tried connecting an external monitor? The screen must be connected through the video port - is that what has blown? Hope this helps a bit


MacBook Pro 2015 install app on external drive including a cloud storage drive

Install the application to Macintosh HD (your internal drive). Then go to your Applications folder, move the applications (after they've been installed) to the external drive. Test to make sure the apps on the drive open properly. Then delete the ones in the Applications folder.

Addition: if you have a cloud storage service, you cannot install the apps onto it, but you can store some of your other documents there while you install MS Office on your internal drive.


Compatibility of iMac G3 hard drives, to try to recover data

Well, while newer iMac drive will work in older one, there is no guarantee it will boot.

There was a limitation during the times of Classic Mac OS on size of boot partition which has to be below 8GB. You have Mac OS X 10.3.9 on that drive so I can't say if it still applies. And maybe if it does apply you might had it partitioned just the way it need to be to overcome it.

Then again getting HDD from that iMac and into it is not that easy. Not that it really hard but still it is not a Mac Pro or standard PC case.

And also keep in mind that you might just break cables when disassembling since it is long time when it was put together and they probably aged and aged cables don't like when you bend them.

So if you are not afraid of the idea of making another iMac unusable or brave, experienced or just curious then go ahead and try. Do not forget to remove power cord, then press power button to get excessive electricity from capacitors off and get yourself grounded.

Still there is an option and it is just buying a used (they are cheap since practically nobody use them) or getting for free a USB enclosure (it could be USB 1.1 or USB 2 — it doesn't matter since that iMac only has USB 1.1 ports anyway yet USB2 enclosure will work too. It even can be 5.25" external CD case provided it internally uses PATA/IDE interface) case for 3.5" PATA/IDE HDD.

After putting your HDD into it you should see content of it. Provided it is not dead, of course.

So good luck and keep us posted.

Okay, so after some searching/googling I found that all problems that I had was because of FileVault bug that makes your OS pause/freeze at login.
This FileVault bug first was seen on Mac OS X Yosemite, I do not know why I faced with this issue on macOS Sierra, which must work perfectly, but nvm, here is my solution.

Solutions
(Works if your FileVault is turned ON, if not, it may be hardware issue)
When you supply a password for your account at login screen your OS starts to unlock the disk. Unfortunately in some cases this process seems to be hindered by some bug with FileVault 2 setups that prevents their systems from immediately unlocking and loading the OS, so their systems now take up to several minutes to log in, or fail to log in as in my case.
Solution 1 - If your OS loads for a long time
Ensure you have a full backup of your Mac using Time Machine.

Go to FileVault tab in the Security & Privacy system preferences and turn off FileVault.

When FileVault is disabled and your drive is decrypted, restart your Mac.

Hold the Command-R keys down at the boot chimes to load your Mac into Recovery Mode.

Open Disk Utility and use it to run a Repair Disk routine, available in the First Aid tab when you select your hard drive. Do this for both the hard drive device, and your boot volume.

Restart your Mac normally and log in.

Re-enable FileVault in the Security & Privacy system preferences.

Solution 2 - If you can't login and stuck watching progress bar loading forever
The above routine works for if you can eventually boot your Mac in the face of this bug, but if you cannot log in and see the system hang on the loading progress bar for hours with no ability to use your system, then you will have to use another procedure:

Reboot your system and hold the Command-R keys at the startup chimes to load into Recovery Mode.

Use Disk Utility to turn off encryption on your boot drive. If this gives you errors, then reboot in Target Disk Mode (hold the T key at the boot chimes) and use Disk Utility on another Mac via a Thunderbolt or Firewire cable to turn off encryption. Alternatively, you can try booting to Internet Recovery by holding Option-Command-R at the boot chimes, which will avoid using your internal drive for any boot purposes.

With your drive unlocked and decrypted, use Disk Utility to verify and repair your boot drive.

Restart your Mac normally.

Use the Security & Privacy system preferences to re-enable FileVault.


Try booting the MacBook Pro into Recovery or Internet Recovery mode (hold down cmd-R when booting for Recovery mode, or option-cmd-R for Internet Recovery mode).

Now you have booted in a "known good" configuration of software which is unaffected by any changed you may have made to the normal operating system on the Mac.

If sleep mode works fine here without kernel panics - you'll know that you have a software related problem.


Is there no "expose" feature (show all tabs) in iterm2 on Big Sur?

Backstory is here: https://gitlab.com/gnachman/iterm2/-/issues/9433
I removed it because it was very slow and buggy. It was some of the oldest AppKit code I wrote, and it showed. Better alternatives are:

Global search — replaces the search feature of expose.
Open Quickly — a faster UI to jump to a tab that searches things like current directory, recent commands, etc.
