Photos.app creates blank images after importing iPhoto library

I have the same problem. It turned out that the photos were gone, recovery had to come from a backup.

You can check if you have the same problem by right-clicking a white photo. Then copy the photo name. Then open a terminal and execute the following commands: cd ~/Pictures; find . -iname <photo name>. If nothing is found, you'll know the photo is gone :(


Is it possibe to upgrade and re-jailbreak (in order to unlock) a 3Gs running on 4.1?

You're a few weeks too late.

There was the Evasi0n jailbreak, which worked on iOS 6.0 - 6.1.2, but iOS 6.1.3 killed it.


How tell Safari to open new tab instead of a window

You can use Safari preferences (⌘ ,) to change this setting, you can use automatically or always for opening pages in new tabs instead of new windows.


Compiling CUPS 2.0 on 10.9: what archflags to use?

I do not have 10.9 and CUPS 2.0, but I had a very similar experience with 10.8.5 and trying to get CUPS 1.7.2 up and running.  The default configure and make ONLY builds a 64-bit set of libraries.  I had success with using the same architecture flags for both the effective CFLAGS and LDFLAGS parameters:

./configure --with-archflags='-arch i386 -arch x86_64' --with-ldarchflags='-arch i386 -arch x86_64'
make clean
make

Before getting this straightened out, many programs (from Spotlight to Safari to Outlook) did not work with 64-bit only libcups*.dylib libraries.

iOS 10 Proactive App Suggestions are Missing

I've figured out how to re-enable the proactive app suggestions in iOS 10:

Go to Settings → General → Spotlight Search
Turn off the top three options:

Siri Suggestions
Suggestions in Search
Suggestions in Look Up

Go back to the main Settings menu.
Close the Settings app (go to the Home Screen).
Lock the phone (turn off the screen by quickly pressing and releasing the Sleep/Wake button).
Unlock the phone.
Go back to Settings → General → Spotlight Search
Turn on the three options you turned off above.
Lock the phone (turn off the screen).

Now, when I plug in headphones or connect a bluetooth speaker, the proactive app suggestions show up as they did in iOS 9!

I found the basics of this procedure in the comments at this reddit discussion.

4 Ways to remove an IOS app: is there a preferred method?

Nope, no advantages between them. In my opinion, just doing a tap-and-wiggle from the home screen is most efficient, but each of the four ways you mention just removes the app. Do whatever's easiest in the moment.


I'll try to answer my own question. I'm not sure this is 100% right.

I suppose frame rate's issue depends on the architecture of Live Photos itself. Total number of frames inside each Live Photo in iPhoneX is 85 frames (look at the picture above):

42frames + 1frame + 42frames = 85frames

Frame rate for all these 85 frames is supposedly 30 fps, but considering just a video part (without a HEIC file), frame rate is 29.68 fps.

Here's a math:

//let's assume that 1/85th is 0.011764,
//truncate that floating point number to 0.011
1 / 85 = 0.011

//let's assume that video frame rate of all 85 frames is 30 fps
//so each frame's contribution is approximately 0.33 fps
30 fps * 0.011 = 0.33 fps

//thus H.265 video portion without HEIC frame will be 29.67 fps
30 fps - 0.33 fps = 29.67 fps

Value 29.67 fps is very close to 29.68 fps.

  I reckon that altogether all 85 frames of Live Photos have frame rate 30 fps, but two H.265 video portions (without HEIC part) have frame rate 29.68 fps.


Can I find out who is currently using my Airport Express speakers, and kick them?

Change the WiFi password. If I am not wrong, you can only access AirPlay speakers via WiFi. So change it and the person in question won't be able to connect.

If you want to find out who it is, go on to your router interface something like 192.168.X.X and see who is connected. Most people name their computers, so will probably show up. Sorry if I can't be more specific.

Also, maybe there is a bug with your AE (doubt it). Maybe you should reset it.


I've had never any problems with upgrades and never lost any files.

You should make a backup — or better, make a bootable clone of your current hard drive:

Buy an external hard drive
Install Snow Leopard on the external drive.
Reboot into the clean external Snow Leopard drive, migrate over users and apps and run all updates. Run from that external to be sure it's a workable copy of your internal drive.
Disconnect the external drive and put it on the shelf.
Reboot back into your regular internal hard drive and proceed with the upgrade to Lion.
Download Lion and run the installer!

Until you're certain that Lion works perfectly, keep the clone around - several months is usually enough time. If you ever need any files from it, just attach the drive and drag-and-drop them. If something goes really horribly wrong, you can boot into the clone, and then clone it back to the internal drive (you'll lose any changes made since you installed Lion). This second drive is really valuable for when you discover three months down the road that one seldom used piece of software won't work on Lion.  You can reboot into Snow Leopard where everything still works and get that one task done. It's a great lifesaver and means you can start using Lion rather than checking that every little thing works perfectly right after the upgrade.

EDIT:
Thanks Trombone for editing my broken-english post, but please, never add your own ideas into my post. My solution uses pure apple tools, so why bother with SuperDuper, when you can do it with nice clean install and Migration Assistant.

I never recommend any third-party products when things can be done with default Apple SW. Of course, you can prefer SuperDuper, it is your way - but not mine. Please add another answer explaining how to use SuperDuper or other awesome tools so that people can have a choice. Let's keep this solution needing no additional tools.

Is it possible to log out of 'mail' on the iPad?

As far as I know, this is not possible. iPad is not made to be a multi-user device. I am in a similar situation myself as I share the iPad with my wife but haven't yet fixed it. Some alternatives:

Set a different account as default account in Settings > Mail, Contacts, Calendars. It could even be a dummy account. At least it means email will not be sent accidentally from your address.
In Settings > Mail, Contacts, Calendars > [Your email account], you can turn off Mail temporarily. It does not provide any security though, anyone can just turn it on again.
If you want to guarantee security, you need to use something like Gmail in Safari and login and logout every time.


The headphone jack had a red LED glowing inside, which clued me in that it thought there was an optical cable plugged in. Plugging and unplugging a pair of headphones resolved the problem.


Is it possible to get OS X to remember my screen arrangement?

Even in 2019 macOS fails to preserve my monitor layout. I wrote a tool called displayplacer that lets describe your monitor layout as a terminal command. I then use BetterTouchTool to execute these profiles via hotkeys. It solved the same problem for me of using the same model monitor at work (in portrait mode) as at home (in landscape mode).

For example, on my 4 monitor setup at home I have this profile: displayplacer "id:A46D2F5E-487B-CC69-C588-ECFD519016E5 res:3840x2160 hz:60 color_depth:8 scaling:off origin:(0,0) degree:0" "id:F466F621-B5FA-04A0-0800-CFA6C258DECD res:1440x900 color_depth:4 scaling:on origin:(-1440,1437) degree:0" "id:4C405A05-8798-553B-3550-F93E7A7722BB res:1440x2560 color_depth:8 scaling:off origin:(3840,-363) degree:270" "id:18173D22-3EC6-E735-EEB4-B003BF681F30 res:1920x1200 color_depth:8 scaling:off origin:(960,-1200) degree:0"

The application DGAgent quit unexpectedly -- repeatedly pops up every time i "ignore", "report" or "relaunch"

The error you're getting from Skype is because you're not using an Intel-based Mac.  Skype only runs now on Intel-based Macs so I assume you're running a PowerPC iMac G5 or something are you?  You also need to be running Leopard/Snow Leopard.  Here's a screenshot of the System Requirements on the Skype Download page:

So, the Skype issue is not related to the DGAgent message.

As regards the startup of DGAgent on login, you can try the following:

Open System Preferences
Click Accounts
Select your account
Click Login Items
Highlight Drive Genius if it's listed and click the '-' button on the lower left to remove it.

This will prevent OS X from attempting to start it on login.  See screenshot below.

Do I need to reinstall OS X after accidentally removing Python?

This question probably has all the answers for you. In short there is no easy way. Your options are:

Recover the files from a (Time machin) Backup, if existent.
Reinstall OSX, e.g. from the Recovery mode pressing  Command+R at the startup screen
Copy the missing files from the Recovery partition (check if the partition is up to date first). E.g. by doing cp -a /bin /Volumes/<your disk name>


How can I change a section's title color by editing the template in iBooks Author?

The layouts easily editable when using the graphical interface of iBooks Author.

Close any documents you may have open to avoid confusion and then open a new document from the template chooser. Start with a template you like and …

View menu -> Show Layouts
make your changes to fonts, colors, layout, etc… on each type of page, working your way down the list.
File menu -> Save as Template…

At that point, save it in the default location and when you start a new document, you can choose your custom layout for starting a new book.


Changing read permissions on /private/etc recursively

Changing the permissions on /private/etc/sudoers is definitely a no-no. The sudo command will fail to work if that file's permissions are not 0440 as you are noticing. This is a security measure -- the command distrusts any permission setting that is less restrictive than 0440 as it allows for potential tampering with sudo permissions on the box.

Normally you'd boot in to single user mode to fix this problem. This lets you log in with elevated privledges so you can do a:

chmod 440 /private/etc/sudoers

and get your sudo command back.

But I found this article that had an alternative that doesn't require a reboot and works if your account has Administrator level access. I haven't tried it, but it seems sound.

Open a Finder window a hit Shift-Command-G to get the "Go To" dialog. Enter /private/etc in the dialog and hit the Go button.

Find the sudoers file in the Finder window, select it and press Command-I to open the information window for the file and change the permissions on the file so they match:

Close the information window and you should be back in business.

All this being said: I would strongly encourage you to rethink changing the permissions of everything under /private/etc to be world readable. This poses a serious security risk (as seen from the way sudo locks you out when you make /private/etc/sudoers world readable) to your machine. Maybe there's another Ask Different question here that'll help you solve a problem you think you're solving by making these unsafe changes?


Is there a non-Rosetta app for Snow Leopard similar to Hotspot Shield?

It doesn't rely on the same system, but the Tor Project can provides you anonymity while connected to the internet.

It fully works under Snow Leopard without Rosetta.

WARNING :

  With this kind of softwares, the final node of the system (last Tor node or the VPN company) can, technically (understand "if it wants"), see all your data going through it !

  The system grants anonymity not secure connection !

  The connection is secured between you and the last node at the minimum, the rest depends on you.

  So, always use secure connections (SSH, SSL/TLS, …) when using these systems.

  By the way, the same principle apply with your ISP, you just have to choose someone to trust !

Connect MacBook Air to Cisco 2811 Console (RS-232 serial)

Serial is not Ethernet, these are two different protocols, so connecting it to your thunderbolt adapter won't work. You can use a USB-serial cable for this, I've had good experiences with cables with a PL2303 chipset on OSX.


Backing up external hard drive shared by two macs to network share without duplication

Another solution is don't use time machine for this type of backup.

I use Chronosync (a GUI for sync) and in this case the scheduler would just skip the sync if the volume is not available. If it is available it would sync the drive to the NAS. You could also use Carbon Copy Cloner for this function.

If you feel comfortable with the terminal and you don't want to pay the money for Chronosync or its ilk, then rsync and chron could also be used.

Good luck!


How to quickly jump to another application without using command tab

If you press ⌘+⇥ quickly, you switch to the last app used and the icons don't show up.

To make sure it works, ⌘+⇥ to your browser. Then to your IDE. Then, quickly press the ⌘+⇥ shortcut. You'll immediately switch to the browser. Do the same again to immediately switch back.

Hope this does it for you.


I had the same problem.  One suggestion on the web was deleting the gmail app from my iPad and downloading it again.  I tried that, but I couldn't download the app again because it said the new version of gmail didn't work on my old iPad.
So now we know why the links weren't working.

So then I went into Google on my iPad and opened my gmail account from there.  It's not as convenient as using the app, but at least the links work fine.

External hard drives do not spin down and overheat

After studying my problem further, I identified the Newertech Ministack 2012 as the cause of my problem. I had to deactivate Drive Genius' DrivePulse, since this program apparently keeps external drives from going into standby. After doing this and switching Newertech USB3 cables for generic USB2 cables, the drives go into standby, but after resuming from standby the fans remain off. This happens in multiple enclosures. It might be a production problem.

You need to have, installed on your iPhone, the public key of the person you intend to send an encrypted message to.

Mail.app on OS X imports the certificates of people who send you mail, automatically. On iOS, you have to do it manually, unless your iPhone is part of a corporate deployment.

It's easy! Simply find an email the recipient has sent to you, tap the checkmark icon next to their name, tap "view certificate", and tap "install".


How to use several languages with the built-in dictionary without changing the interface language?

On iOS7: the dictionary can be selected from the definition screen.

On iOS6:
From my experience, switching the keyboard language is enough to change the dictionary language.

First you'll have to add the keyboards you need (this is a one-time operation):

Go to Settings -> General -> Keyboard -> Keyboards -> Add New Keyboard.
Select all the languages you're interested in.

Now you can use the key that is located to the left of the space bar in order to use a different keyboard (a list is displayed on long press).

Start iMac in Target Display Mode without dedicated keyboard

There are two options that I'm aware of which may meet your needs:

Use the 1Keyboard app. This allows you to pair your computers via bluetooth and then use 1Keyboard to send the CommandF2 keyboard shortcut. It basically allows you to use one keyboard with multiple devices.
Use VirtualKVM. This was designed specifically for people wanting to use their iMacs in target display mode, and works especially well in situations where you want to connect a MacBook to the iMac. For example, if you plug your MacBook into your iMac via Thunderbolt, this extention will automatically switch the iMac to Target Display Mode, allowing you to use your iMac as a monitor. It also switches off the Bluetooth on the iMac, freeing up your mouse and keyboard to pair with your MacBook (assuming you're using a bluetooth keyboard and mouse). When you unplug the MacBook, the iMac's Bluetooth will be powered back up and the monitor restored.

The above options should work fine. If you're a more advanced user, you could also check out this Super User question.


Is it safe to thin out Time Machine backups by deduplicating files?

No, you cannot run most deduplicator applications on a time-machine backup.

Time machine makes extensive use of hard-links internally. Any application that is not aware of this will find hundreds or thousands of false duplicates (which are really hard-links to the same file), and proceed to hose your time machine backup. Apple also seems to do some filesystem-specific stuff in the backup too, which is why it needs to be on a HFS+ volume (either a entire drive, or a .sparseimage on a network share).

A lot of the complexity within the time machine mechanism is poorly or undocumented entirely, and if you break something, time machine will simply not work, without any meaningful documentation. If your deduplicator is hard-link aware, it may work, but it has equal chances of hosing something, from which you cannot recover.

Really, there does not seem to be any decent tools for managing time-machine images, unfortunately.


Why am I seeing these weird characters in the popup that asks for my password when I try to update Adobe Flash on my Mac?

Best strategy to transport a MacBook backup

Have you considered using Time Machine to backup your computer to an external drive? If you change the Time Machine backup destination in System Preferences > Time Machine, it will stop backing up to your Time Capsule, and backup to your external. Then once it has completed a backup to the external, just point Time Machine back to the Time Capsule.

Carbon Copy Cloner is one of the best applications for this. It is free and makes a complete bootable backup of your hard drive to an external. I've used Carbon Copy Cloner many times and I highly recommend it.

SuperDuper! is another option. It allows you to create a fully bootable backup of your hard drive. The backup part is free, so you don't need to pay the $27.95 for the scheduling part. I've used SuperDuper! as well and it is a great application.


That's odd. Since you've put nothing on it, you should just hold the power key and start it up again.

If it hangs, you can boot to recovery and repair the hard drive catalog structure. Nothing should download until you log in to the first account and set automatic updates, etc..

You can isolate it from all network and iCloud settings and just set up a test account. It's easy to clean a user out and start over with the "out of box" assistant once you're in to the first user account without any network setup.


Force Quit Disk Utility to Cancel 7 pass Erase and Now Disk is not usable

You needed to recreate a filesystem. You tried diskutil eraseVolume disk2 but this is invalid. See man diskutil or diskutil eraseVolume --help for details.
Firstly you need to tell diskutil what filesystem (if any) to use and secondly while in some odd cases (RAID for example) you create a filesystem on the whole physical disk normally it is on the partition. From your picture disk2 is the physical disk and disk2s2 is the partition so you want something like this:
diskutil eraseVolume JHFS+ WhateverName disk2s2 where :

JHFS+ is the filesystem you want (in this case journalled HFS+).  Valid values can be seen by entering diskutil listFilesystems but from your picture it seems you had a HFS filesystem before.
WhateverName is the volume name you want (can be any valid characters, quoted if necessary)
disk2s2 is the partition you want to create the filesystem on.

What probably happened
From your picture disk2 is your physical USB drive.  When you format a drive in Disk Utility macOS creates a small file called a partition table at the start (and if a GPT disk the end) of the disk.  This file holds information showing where partitions are on the disk and their type.  It will then normally create a small (invisible) 200MiB EFI partition (disk2s1) followed by one or more other partitions (disk2s2, disk2s3 etc) that you request.
In your case the second partition was a 256GB HFS partition.  This was probably journalled HFS as it is the default, but not necessarily - the filesystem type code AF00 doesn't distinguish journalling.  You can see from this support doc Apple recommends it in many cases.
When you started writing zeros to disk2s2 it destroyed the filesystem by overwriting it with zeros.  The partition table entry showing the start, end and type (AF00) remained.  Therefore creating a filesystem in the partition fixed it.

Note on cleaning
Overwriting 7 times with zeros is a massive overkill.  Once is enough and more than that is a waste of time.
See this stackoverflow question: How does a 7- or 35-pass erase work? Why would one use these methods?
or this askubuntu question: Possibility of recovering files from a dd zero-filled hard disk

How do you add more than one phone number on iMessage?

The only way to get a phone number associated with iMessage is for that phone number to be provisioned to an iPhone and have SMS messages active from the carrier. At that point, you can sign in to iMessage with your Apple ID / iCloud account and it will verify the phone number is actually connected to that device and your AppleID will then inherit that phone number.

At that point, you can remove that phone number from that iPhone and use another Apple ID with iMessage. With dual sim / esim you might even get both numbers active on one iOS device.

So, unless you can borrow an iPhone long enough to get your carrier to provide 5 minutes of service to an iPhone - long enough to register, you will be stuck with an email address for iMessage.

By this process, you could have more than one phone number associated with one Apple ID. You cannot however get one phone number associated with more than one Apple ID as the last ID to get registered with iMessage removes that number from any other Apple ID that used to "claim" that number as deliverable.


Running Mavericks. Need to return to Snow Leopard

First I backed everything up on time machine, and I made a manual backup of photos, music, downloads, and documents to another HDD.

Next I put in the install disk from OSX Leopard 10.5.. Mavericks will let you enter the install process right from the desktop on Leopard 10.5, but nothing past 10.5. (If you don't have leopard you can probably get one off ebay, or find it on the internet somewhere.

The computer will restart into installation mode from which I erased the HDD. Then I installed 10.5 Leopard.

After the Leopard install you can upgrade to any version you want to. I used snow leopard because it only uses 1 gig of RAM.

My computer runs much faster again, like when I bought it. Sure there are some apps that don't work, but I have everything I need here.

How does the Facebook Camera App know who I am the first time I go into it?

This was covered by MG Siegler over at Paris Lemon last week, the explanation of how it does it is here.

Basically, iOS provides it's own Keychain functionality and if you know the Keychain key, then you can save and read data between apps that you write.  In this case, the Facebook Camera app is reading data saved by the Facebook app.


Maybe this isn't the answer you wanted to hear, and maybe also it's my paranoia about RAM (I made sure my new rMBP maxed out at 16 GB, particularly because RAM is now soldered to the motherboard), but the fact is that it's the cheapest upgrade possible on your computer. When you don't have enough RAM, the performance hit you take, when the computer starts paging to the hard drive, is simply monstrous.

Honestly I think 4 GB of RAM, today, is on the low side. Only the lowest end Macs currently for sale feature 4 GB of RAM, and some come with 16 GB standard. Mavericks has a compressed memory feature that should supposedly help with RAM pressure, but there's only so much that can be done. Your computer can certainly use 8 GB of RAM and most likely 16 GB of RAM, as reported here. I just checked Newegg and you can get 2 x 4GB RAM modules (for a total of 8 GB) of RAM for about $70 and 2 x 8GB for about $140 (reputable brands in both cases).

Then there's the possibility of replacing your hard drive with an SSD, but that's a much more expensive upgrade, and RAM should help a lot already. If you plan on staying with this computer for a long time, it's a possibility you definitely should consider since it breathes new life into any computer with a mechanical HDD. Also, prices are constantly falling, so if a RAM upgrade helps you now, you can hold out for a bit and get a good deal on an SSD later.

If it helps you somehow, I can happily report my previous computer, a mid-2010 15" MBP with 8 GB of RAM and a 300 GB SSD, absolutely flies with Mavericks installed, and I consider myself a fairly heavy user, including Parallels running most of the time. Most apps opened within a single Dock bounce. My wife needed a better computer and I needed more disk space (my average free space on the last few months was 10 GB or so), so I ended up ordering a retina MBP. But I can assure you that, other than the disk space problem, I could easily keep using that computer for another couple of years, it was just that fast.

From Menu Bar select Go -> Go To Folder.
Copy paste this path /Library/Preferences/SystemConfiguration/.
Locate the file com.apple.airport.preferences.plist and make a copy of it with a name like com.apple.airport.preferencesOLD.plist ( for backup just in case).
Move the original file from the previous step to your desktop to enable
editing.
Open the file with Xcode (or any other text editor app)
In PreferredOrder array you can see the full list in descending
sort.
Change the order or delete a network if you don't want it in the
order.
Move the com.apple.airport.preferences.plist back to
/Library/Preferences/SystemConfiguration/ folder

As you can see the value of each item is wifi's ssid.

You can match wifi ssid with yours wifi name from the dictionary KnownNetworks (above of PreferredOrder in com.apple.airport.preferences.plist file).


2017 MacBook Pro starts with a question mark folder when there is less charge and when it wakes up from sleep

I solved this unchecking the option "Put the hard disk to sleep when possible" under System Preferences > Energy Saver, both in "Battery" and "Power adapter" tabs.


According to this article, it sounds as game progress is only saved when you sign in using a Facebook or Google account.   If you aren't signing in to the game that way, it will not save / backup your progress.

Also, according to this article, the company offers no guarantee that game progress would be saved.   Sounds pretty shady to me.


Where is system.log located? (In the filesystem, outside of Console.app)

Right click it in Console.app - Reveal in Finder :)

For completeness, it's located in /private/var/log.


In file dialogs you can press Cmd-Shift-G (just like in Finder) to enter the path to any folder/directory you want to open.


How can I delete a photo off my camera roll, but keep it in my album?

My workflow for this - not using iCloud - is:

import the photos into an app (I use Lightroom)
label photos I want to end up on my iPhone with "for-iphone"
export photos labelled "for-iphone" to a folder of your choice (I use "Pictures/for-iphone")
in iTunes turn on "Sync Photos" for your iPhone [note: find "Sync Photos" by plugging in your iPhone, opening iTunes, clicking on the little phone icon to the right of the "Music" dropdown, then clicking Photos in the list below]
at "Copy photos from:" pick "Choose folder..." and navigate to the "Pictures/for-iphone" folder or your equivalent
Hit Done

Your photos will be uploaded to your phone independent of the Camera Roll.

Each time you sync any newly-added photos in the for-iphone folder will be added to your phone.


External monitor options for MacBook Air?

The Thunderbolt ports are also mini-Displayport compatible. So you can hook up pretty much any display (Displayport, HDMI, DVI, VGA) with the proper adapter.

For high-resolution panels (greater than 1920x1200), you should try to go with Displayport if possible, as the mini-Displaylink to dual-link DVI adapters have been problematic for many people (this isn't an issue for single-link DVI displays, which comprise all but the largest DVI displays around).


How to automatically connect VPN when connecting to a network?

LifeHacker has answered your prayers (with Apple Script). You will obviously need to replace VPN University with the name of the service pertinent to you, and SSID University with the name of your university's SSID.

on idle
    set mySSID to do shell script "/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | awk '/ SSID/ {print substr($0, index($0, $2))}'"
    if ((mySSID as string) is equal to "SSID University") then
    tell application "System Events"
            tell current location of network preferences
            set myConnection to the service "VPN University"
            if myConnection is not null then
                if current configuration of myConnection is not connected then
                    connect myConnection
                end if
            end if
        end tell
        return 120
    end tell
    end if
end idle

You can save this as an application any way you want, I prefer to go through Automator, though Script Editor, AppleScript, or XCode are also capable of compiling AppleScript, save it as an application, mark it to start on log in, then if you want to be fancy, you can either tell XCode not to have its icon on the dock, or edit the .plst file in the application bundle as such:

<key>LSUIElement</key>
<string>1</string>

This little hack per user ianneub.

Note I have tested the applescript piece only on my early '11 15" MBP OS X 10.10. Your mileage may vary if you're running El Capitan (I bet it doesn't though). This post comes with no warranties of any kind, and may give you gonorrhea.

EDIT:
Note I updated the original script to check for a specific SSID, then perform the actions. I'm on my WinXP machine right now, so this is an untested, but relatively safe change. I found the info on getting the current SSID here and info on string comparison here.


It sounds like your update failed for some reason. You're correct, the icon you're seeing on screen means that you need to connect it to iTunes. You need a micro USB cable to do this.

What happens if you plug it into iTunes?


Search iOS App Store by sharing features included with app

No, there's no way to search the App Store like that as Apple doesn't expose that data. Most apps don't even list the ability in their description text, so while you could try running a Google search, e.g. https://www.google.com/?ion=1&espv=2#q=site%3Aitunes.apple.com%20text%20share%20extension, unfortunately it won't work too well.


How does Font Book.app determine the "Design style" for a Smart Collection?

OK, I think I figured it out...  Opening a font in RoboFont, I scoured all the obscure meta-info available and finally found the entry that seems to correspond to what FontBook uses for the Design Style in the section called Panose (a term I had never heard of!).  Long story short... FontBook seems to probably use the Proportion to determine the style.

E-Mail with attachments (3,5 MB in Entourage. Why?

This isn't an Apple or Entourage issue, this is normal behaviour that happens when attachments are encoded to be sent with emails -- encoding the data to the email format makes the attachments roughly one-third heavier.

This has nothing to do with the Apple filesystem.

There is no way to stop this happening. If file size is a problem, consider uploading to an FTP server, or using a system like Box.net, YouSendIt, or DropBox to share the files -- these methods don't require encoding and will not increase the size.


How do you change colour scheme between *panes* inside iTerm2 + oh-my-zsh?

The easiest way of doing this is to install the "Shell Integration" tools, using this menu in iTerm:

Once you've done that you will have access to several iTerm-specific tools, including it2setcolor which lets you easily change the colors.

For example, I use this as part of my ssh alias for connecting to a remote server:

it2setcolor preset 'Solarized Light'

so whenever I ssh somewhere, iTerm automatically changes the 'Theme' to 'Solarized Light'.

(Run it2setcolor with no args to get a usage summary.)


iPad mini must be plugged in to turn on even if battery is fully charged

Sometimes it helps to do a soft reset:
hold the Power button and the Home button at the same time, keep holding, the unit will switch off, keep holding, then when you see the white apple logo let go and let the ipad start up normally.
Try again.


Is it a bad idea to have a shared Apple ID for purchases that also is used for iCloud?

In your first question you ask:

  what should be done if there is currently 1 Apple ID (my account) that is used for all the purchases and also is used for my iCloud, and I want to add another user to the mix?

To enable you to share purchases the new user will use your Apple ID for the App Store and iTunes. This use would then create a new Apple ID or use an existing one for the iCloud portion. They would assign this Apple ID to iCloud by clicking Settings -> iCloud -> Account.

Secondly you ask:

  What problems will there be if my Apple ID is used for the purchases on all devices and also used for my iCloud account for my user, while a different Apple ID is used for iCloud for a different user?

This is the solution I noted above, and the preferred method. By separating iCloud accounts for each user you'll have less devices competing for the 5 GB of free space allotted by default.

In summary:

All devices use Apple ID for Store (Settings -> Store -> Apple ID)
Your devices would use your Apple ID for iCloud (Settings -> iCloud -> Account)
Other user's devices would use a unique Apple ID for iCloud (Settings -> iCloud -> Account)
There are no drawbacks to sharing an Apple ID and using individual accounts for iCloud.


XCode Problem - Couldn't load settings from contents.xcplayground

This happens when you zip and unzip files and Mac turned some files into .xml file depend on your mac settings. The solution is:
right-click the "xxx.playground" file -> show package content, you will see the "contents.xcplayground" file. Right-cilck this file and go to "Get info". Now in file name and extension section, remove the .xml at last.

Do the same for "contents.xcworkspacedata" under the "playground.xcworkspace" workspace folder.


How to fix usbmuxd spam in console when iPhone is connected?

The spam arrived with a recent update to iTunes.  It happens in both Snow Leopard and Lion.  Short of downgrading iTunes versions until the messages go away, there's probably nothing you can do about it.

An update:

The usbmuxd spam only happens when you have a device (iPhone, etc) plugged in and listed in iTunes under 'DEVICES'.  One obvious workaround is to leave your devices unplugged.  A more useful workaround is to just eject them in iTunes – the spam will stop and your devices will continue to charge.


How to limit size of Gmail IMAP log files?

Organizing user home directory between SSD and HDD

You can use aliases for those directories containing lots of data. Example:

/Users/you/Movies -> /Volumes/MyStuff/Movies
/Users/you/Music -> /Volumes/MyStuff/Music
/Users/you/Pictures -> /Volumes/MyStuff/Pictures

The easiest way to wipe the contents of the previous drive is to open Disk Utility, select your drive, and then select the 'Erase' tab. Choose the options you want and wait until it finishes.

How to obtain previous (not the current) passwords from keychain on iOS?

The older passwords are unfortunately not stored in the keychain and cannot be recovered from the iCloud backup.
Your only option is to use the account recovery methods made available by that specific web site. For example many web sites allow account recovery through sending a password reset link via email.


How can I get Find My iPhone to work on a Jailbroken iPhone on iOS 5 with no data plan?

Location on an iPhone requires a data plan. This is because your iPhone’s GPS downloads an “almanac” file to help locate itself. This can’t happen over Wi-Fi, as these files are not on the internet, but on the internal network of your carrier.

As for your iPhone not using the Wi-Fi to locate itself, that’s probably because the network is not yet in Apple’s database.

There’s must be something broken if the iPhone is not showing up as online. There can be two possibilities. Either Apple has configured Find My iPhone only to use GPS or some tweak or a bad jailbreak is not allowing the findmyiphoned (process responsible for responding to Find My iPhone requests) to work or launch properly. As there can many things that can cause this problem, I would suggest first booting up in safe mode (SBSettings can do that) and seeing if the problem is resolved. If it is, that means a tweak caused a problem. If it isn’t, that means you did a bad jailbreak. In the latter case, a restore is the only option.

Set a personalized alarm clock schedule on iPhone

You can't do this with the Alarm mode within the default Clock app in iOS. However, you can do this using either the Reminders app or the Calendar app.

Wakeup alarms

First of all, if you want this to work as a wake-up alarm in the same way as the Alarm in the Clock app, you need to change the sound associated with the app. If this is what you want, these are the steps involved:

Go to Settings
Tap on Sounds
Scroll down to and tap on either the Calendar Alerts option or the Reminder Alerts option
Scroll down to the list of Ringtones (past the alert tones) and select the ringtone you want to use as your alarm. If you want to use a traditional 'alarm' sound you will need to scroll to the very bottom and tap on Classic to select the one you want.
Once you've selected it, go back to the main Settings screen and exit

NOTE: Keep in mind that when you make the above change it'll be set for all Reminders or all Calendar Events - so you will need to decide which App it is you want to use with your new 'alarm' sound.

Setting your schedule

Now go to the app you chose for this (i.e. either the Reminders app or Calendar app) to set your schedule. The process for either will basically be the same, but in these steps I'll use the Reminders app as my example.

Launch the Reminders app
Tap on the + sign to create a new reminder
Give it some sort of meaningful name
Switch on Remind me on a day
Select whichever date is the very next Monday you want the alarm to go off on
Set the time you want it to go off on that Monday
Tap on Repeat
Select Every Fortnight. (see Notes below)
Now repeat the same steps for each of the days, making sure you pick the date you want the alarm to go off and choosing to repeat it every fortnight
Exit the Reminders app. Your schedule is now set.

NOTES:

The Every Fortnight option may be a localised option in my region. If it's not available, select whichever option is for two weeks. If you have no such option, you can tap on Custom and then choose a Frequency of Weekly and select Every 2 weeks.
If the actual time is the same for each alarm, regardless of day, then at Step 8 you could choose a custom repeat of Daily that repeats every two days. In this scenario you could get away with a single reminder and totally skip Step 9 altogether.


How to keep both Mavericks menu bars opaque in two monitor setup

I just found a fix for this. Check out this video I made.

Step 1. change the order your displays are in.

Step 2. set to opaque.

Step 3. change back the order, now you have opaque on both bars.


For obvious security reasons, in order to change one's account Email, you need access to that account in the first place. If you don't have access to the email in question (and you can't login) then you are pretty much out of luck. The verification email will go to the new email address to confirm it.

In the past few days, Apple added a Google-like mechanism to allow you to access your account in the event of a problem with the primary email. Essentially it allows you to answer three security questions. If you don't or can't access those, then a backup email is provided (and verified) so they can help you recover your account.

But… these things must be done before you lose access.

Pair a bluetooth mouse directly with Macbook Air

The mouse has a fixed connection to the dongle, you can not use a normal bluetooth connection
Once the bluetooth dongle fails or you lose it, you can't simply buy a new dongle, since you are unable to pair the mouse to it again. This means once you will end up with a useless mouse

Note: You have to dig a little deeper into the reviews/questions for example here on Amazon to verify that you can not buy dongle replacements


The RTFD format is actually a package format that allows it to have related files attached, like images. If your document has any files attached, you will not be able to save it as a straight RTF.
Try right clicking on your RTFD file and select "Show Package Contents" and you will see the contents: the "core" RTF file is usually named TXT.RTF and the other files also present.
You can actually grab the RTF straight out of the Package without even going through saving it manually via TextEdit.app.


iPhone stuck "Removing iCloud Data..." after iCloud sign out

After an hour I decided there was something clearly wrong, so this is what I did to resolve it:

Powered down (long press on the top button, slide to power off),
Powered up and entered password,
Opened Settings (I appeared to still be still logged in to iCloud, but iCloud was off - it seems that things were just half completed in the original sign out),
Signed Out of iCloud again (this time it finished almost immediately).

The In-App-Purchase test then worked fine.


After upgrading iTunes all my media has disappeared

I kind of fixed it. I signed out of iTunes, then my music appeared! It seems to remain in place when I signed back in, so maybe, all is good


iPad Mini 1st Gen (Jailbroken), want to upgrade from 7.1.2 > 9.0.2, not 7.1.2 > 9.3.5, don't know where to start.

The short answer is, you can't.

First, for the most part, using SHSH blobs to install an unsigned version of iOS hasn't worked since iOS 6. There have been some recent developments with a tool called Prometheus, but it will only work on more recent versions — at the moment, that basically means iOS 10, though I am greatly simplifying the situation.

Second, though it's a moot point, you would need to already have saved the SHSH blobs for 9.0.2 while it was being signed/while your device was running 9.0.2.


(Tested on OS X 10.8.2; other releases may be slightly different.)

You can change the system’s limit on ptys with the sysctl command.

sudo sysctl -w kern.tty.ptmx_max=255

This should immediately let you open more ptys.

To set this automatically after each reboot, put the following line in the /etc/sysctl.conf file:

kern.tty.ptmx_max=255

(Note: I did not try this, but, from a look at the source code, it looks like launchd does process this file.)

This file may not exist; if you have to create it, you should probably be sure it has restricted ownership and permissions:

sudo chown root:wheel /etc/sysctl.conf
sudo chmod 644 /etc/sysctl.conf

Eventually, you may run into some other per-process or per-user resource limits (e.g. total number of processes per user, and total number of open file descriptors per process).


Is there an app that allows an iPhone-to-iPhone local network call with shared music?

Short answer no. I found a link to an article that explains this.

  Playing music or any other audio while on a phone call is easy:

  While on an active phone call, tap the Home button to get to the home
  screen Open the Music app, find any song or podcast, and press play
  Return to the phone call screen by tapping the green titlebar Music
  (or any audio) plays immediately, but instead of outputting through
  the external speakers, it will be played through the ear speaker. This
  prevents the music from being piped through to the other end of the
  phone, and that means the other end will never know you’re jamming to
  Milli Vanilli to make it through their tortuously boring phone calls
  and wait times.


How can I route two audio sources simultaneously as inputs to Skype?

SoundFlower

This is the traditional solution, and it is free. Although I am not sure if it's compatible with Lion.

Once you have it installed, you'll need to get familiar with the Mac OS X system utility, Audio MIDI Setup, in the Utilities folder.


Unable to unlock System Preferences in High Sierra

I found a working solution to this on this Apple support community thread, Can't install programs and unlock settings:

  OSX apparently needs to regenerate a fresh auth.db from /System/Library/Security/authorization.plist.

  This can be triggered in terminal with the following command: sudo mv /var/db/auth.db /var/db/auth.db.old

  After rebooting the system everything works as it should be.


Replacing a cracked MacBook Retina Display with third-party hardware?

Apple doesn't sell replacement parts to users, only to their authorized resellers and service centers. However, some used Apple screens are available in the aftermarket, as, for instance from ifixit.com.

I think your choices are:

A) Have Apple or an authorized shop replace the cracked screen;

B) Buy a used screen and install it yourself;

C) Buy a used MacBook (perhaps you could find one with broken electronics, or a bad keyboard or inoperative logic board) and take your chances that its screen will be good;

D) Find a non-authorized repair shop that can replace the screen (thus offloading the "where to get the part" challenge onto the shop, along with the risk that the "new" screen won't work); or

E) recycle your MacBook and replace it.

How does using GMail via IMAP or Exchange affect battery life?

I have an IMAP and an Exchange email account on my iPhone 4S and when I only use Exchange my battery drains faster than when only using IMAP.
While I have configured IMAP to check for new email every 30 min, I must say I get lots of email in my Exchange account, that probably worsens the drainage.
Apple recommends here to "Turn off push mail", so it is a known fact.
How much is battery affected? I can't give you a number, it depens on many factors (how often data is fetched, number of emails you get, size of the emails you get) so just test it: disable Gmail IMAP, configure Gmail ActiveSync and compare.
--EDIT--
After reading Michiel's answer below I was curious and googled "push vs. fetch iphone" and have seen quite a few debates. The outcome tended to be that using push conserves battery life, but some opinions just said "it depends".
My configuration is probably unbalanced and that's why Exchange uses more battery than IMAP (which is fetched every 30 min and not the 15 min as I posted in my original answer, now corrected). Please take this answer as my personal (non representative) experience.
In the link above Apple also recommends to "Fetch new data less frequently".
So again, test it and find out for yourself.

How do I report an unauthorized copy app uploaded to App Store?

Try getting in touch with Apple via the App Store Content Dispute page.

  If you believe that an application or Search Ad available in the App Store violates your intellectual property rights, you can use this form to submit a claim to the App Store Legal Team.

If you suspect copyright infringements, you can use the info provided in the Legal Claims of Copyright Infringement page.

Note: Please don’t treat this as professional legal advice of any sort. Just a couple of pointers to get you started towards potential resolution.

Windows: Why does Bonjour's mdnsNSP.dll inject itself into every process?

Sounds like you are curious about security and privacy. If so, your question should be "Why does my operating system allow third-party software to become aware of and affect every process?" or, "If I care about security and privacy, why am I using Windows?"

Bonjour is Apple's implementation of zero configuration networking. A very long time ago, and very shrewdly, Microsoft began making its OS and most of its processes, and the file system as well, network aware. Most notably, the file manager Windows Explorer was made network aware, which was also basically the same application as the native web browser, Internet Explorer,  and this change in the behavior of the operating system led to antitrust cases regarding which web browsers shipped with Windows. By now, I imagine, everything running in Windows is probably network aware, and are identified and advertised as 'Services' to the Windows kernel and the network. If so, it makes sense that Bonjour would make itself available to every processes to enable zero configuration networking.


Can I boot my mac from my old windows hard disk?

This is not possible.  Windows is not natively capable of being moved from machine to machine in that manner.  You could install a fresh copy of Windows on external media and copy all of your old files over.  Its time consuming but here is a link to some instructions regarding how you can accomplish this.
Is it possible to use Boot Camp with Windows 10 from an external HDD?


The Apple Lightning to USB adapter is not powered, so the trivial answer is no. As you've already realized, many powered pass through USB devices exist and some surely have enough power For most USB bus powered devices - even a motor and optical drive.

The slightly more complicated answer is also no. The software interface and software drivers to recognize a burnable media device isn't programmed into iOS (or iPadOS).

All your good work connecting the device will be for naught without software changes. I bet someone with a jail broken phone and skills could cobble together open source drivers and attempt to load them, so I'm not saying that this isn't theoretically possible, just that it's not plug and play due to software issues and potential power issues.


Is it possible to convert Blurays to my iPad?

Absolutely!  You'll need a program to rip the Blu-Rays to your computer, then you'll need a program to convert them to a format that your iPad can understand (like HandBrake).

Lifehacker has a good guide that works with both Mac and PC for ripping Blu-Ray discs.


Is There a Wired Mouse or Track Ball That Supports Gestures in OSX?

Okay, so I found out that there is one option that kind of supports Apple's Magic Mouse and Magic Trackpad gestures.

The Wacom Bamboo Pad allows you to control your Mac with touch gestures and comes in a wired, USB model.

If anyone finds another solution, please post it, because I was really looking for a wired mouse that can do this and would appreciate the input.

Thanks again,


Kernel panic - Mac won't allow me to log in

Something like that happened to me after upgrading to El Capitan.
The system would only behave "normally" if I started it in safe-mode (https://support.apple.com/en-us/HT201262)

So I tried restarting it again in verbose mode (https://support.apple.com/en-us/HT201573) and just before the "panic" message, there was a reference to a kernel extension (kext) for a very old program that I didn't even remembered installing...

I fixed it by restarting the system again in safe-mode and unloading that kext.
The next boot, the system began again working ok...

Can't reclaim empty space on main macOS partition [macOS Mojave]

You need to first remove the second EFI partition. Enter the commands given below.
diskutil erasevolume free none disk0s3
diskutil apfs resizeContainer disk0s2 0

Explanation:
The disk0s3 slice occurs after the disk0s2 slice. The free space exists after the disk0s3 slice. The command diskutil erasevolume free none disk0s3 will remove the disk0s3 slice from the partition table, thus increase the size of the free space. The diskutil apfs resizeContainer disk0s2 0 command can then be used to add the free space to the disk0s2 slice. In other words, disk0s3 is in the way and is preventing you from adding the free space to disk0s2.


iphone 3g jailbreak: from 4.2.1 to 4.3.x. Is it possible?

No. 4.2.1 was the last version of iOS supported by the 3G.


iPhone has been updated successfully but why is it still stuck on connect to iTunes?

Those versions are no longer signed.

Apple has stopped signing iOS 10.3.1 so it will not work to downgrade to. You need to use iTunes to update back to iOS 10.3.2 and your phone will work again.

Right-click on one of the file types you wish you open in the VM and click "Open" or "Open With..." if the program already has an associated application (if you selected "Open", in the window that appears, check the "Select the program from a list of installed programs" radio button and click OK).

In the window that appears there should be a VMware icon in the top-left that says "Default Host Application", select it and click OK. (You can also check the "Always use the selected program to open this kind of file" so that it opens with the host application next time too).

If the VMware icon is not in the top-left, you may have to drop down the list with the "Other Programs" heading and you should see it there instead.

The document in the VM should now open in the default application on the host. For example, a pdf should open with Preview and a docx with Word for Mac.


Rescuing a MacBook Pro 13-inch, Mid 2009

Too late for this question, but why do people not consult Apple about Kernel Panics? Maybe you had other choices, yesterday.

My July 25 answer to similar question:

Read Apple's own support page, About Kernel Panics , and MacWorld's How To Troubleshoot a Kernel Panic. You'll be able to isolate the problem and from there, know what steps to take, many of which are quite simple.


Recommendation for an iOS & Mac app suite with iCloud support for editing RTF files?

I'm the developer of an app called RTF Write which does exactly what you're looking for -- it also supports iCloud Drive and iCloud HandOff.  It's free for iOS, the OS X version is $2.99.

How do I remove unused partition (El Capitan)?

You can't move the start block of a CoreStorage Volume Group ("BOOTCAMP" in your case) non-destructively (OK, there is a workaround: please check the Scattered Physical Volumes method at the end of my answer). The same is valid for non-CoreStorage partitions with on-board tools. AFAIK only iPartition and gparted work for the latter. Therefore you can't easily reclaim empty space with a lower start block and an arbitrary size and add it contiguously to existing CoreStorage or non-CoreStorage volumes.

You may either remove the partition Macintosh H or repartition the internal drive. I recommend the latter because removing one partition will not increase the size of the second partition!

Preparation:

Attach a backup drive and use Time Machine to backup BOOTCAMP.
Detach the backup drive
Restart to Internet Recovery Mode by pressing alt cmd R at startup. Booting to Recovery Mode is not conducive because the Recovery HD will be removed in one of the steps below. And you can't remove a partition used as a boot volume.

The prerequisites are the latest firmware update installed, either ethernet or WLAN (WPA/WPA2) and a router with DHCP activated.
On a 50 Mbps-line it takes about 4 min (presenting a small animated globe) to boot into a recovery netboot image which usually is loaded from an Apple/Akamai server.

I recommend ethernet because it's more reliable. If you are restricted to WIFI and the boot process fails, just restart your Mac until you succeed booting.

Alternatively you may start from a bootable installer thumb drive (preferably Yosemite or El Capitan) or a thumb drive containing a full system (preferably Yosemite or El Capitan). If you boot to a full system and login as admin you have to prepend sudo to execute special commands like gpt ...!

Either remove one partition (not recommended)

Open Utilities -> Terminal
Enter diskutil list
Enter diskutil umountDisk /dev/diskX with diskX: disk identifier of the CoreStorage volume (probably disk2)
Enter diskutil umountDisk /dev/diskY with diskY: disk identifier of your internal drive (probably disk0)
and
Enter gpt -r show /dev/diskY to get an overview and the index number of Macintosh H (probably 2)
Enter gpt remove -i 2 /dev/diskY with diskY: disk identifier of your internal drive (probably disk0)
Enter exit and quit Terminal

Or remove all partitions (recommended)

Open Utilities -> Terminal
Enter diskutil list
Enter diskutil umountDisk /dev/diskX with diskX: disk identifier of the CoreStorage volume (probably disk2)
Enter diskutil umountDisk /dev/diskY with diskY: disk identifier of your internal drive (probably disk0)
and
Enter gpt destroy /dev/diskY with diskY: disk identifier of your internal drive (probably disk0)
Enter exit and quit Terminal
Open Disk Utility and partition your internal drive

Either reinstalling OS X booted to IRM

Quit Disk Utility and open Restore OS X
Install and configure OS X
Download the latest OS X and upgrade to OS X El Capitan
attach your backup drive
Use the Migration Assistant to import your old users/data

Or reinstalling OS X booted to a bootable El Capitan installer thumb drive (recommended)

Quit Disk Utility
attach your backup drive
Install OS X El Capitan
Use the Migration Assistant to import your old user(s)/data

If you hesitate to reinstall OS X and migrate your data, you may convert the first OS X partition of your disk to a Physical Volume and add it to your Logical Volume Group. After extending the Logical Volume, BOOTCAMP will cover almost all of your disk. The content of BOOTCAMP will be preserved.

The approach is similar to a Fusion Drive (two Physical Volumes -> one Logical Volume Group/Logical Volume) however using only one disk.

Scattered Physical Volumes method

Attach a backup drive and use Time Machine to backup BOOTCAMP.
Detach the backup drive
Restart to Recovery Mode by pressing cmd R at startup.
Open Utilities -> Terminal
Enter diskutil list to list all partitions
Enter diskutil cs list to list the CoreStorage items
Enter diskutil cs addDisk lvgUUID diskYsZ to add a Physical Volume
lvgUUID is the UUID of the Logical Volume Group, diskYsZ is the disk identifier of the empty partition Macintosh H (probably disk0s2). The content of the partition will be destroyed!
Enter  diskutil cs resizeVolume lvUUID size to extend BOOTCAMP
lvUUID is the UUID of the Logical Volume, size: size in t, g, m, k or b (in your case 250g. If you get an error regarding missing space use 249g).
Enter exitand quit Terminal.
Open Disk Utility and verify the CoreStorage Volume Group.
Reboot to your main volume.

The pros:

it's fast; it takes about 3 minutes.

The cons:

your CoreStorage LVG is non-contiguous and fragmented.


iMac issues: indicates hard disk needs replacing and can't get through AHT, should I do any other tests?

It doesn’t necessarily need a hard drive. Have you erased it and tried installing an OS?
You’ll need an external bootable OS for this on 2011 era hardware.
Only if you can’t get that working would you need a repair. A failing disk usually doesn’t cause shutdowns without logging a prodigious amount of IO errors and any technician should be able to read the SMART statistics to conclude the drive is malfunctioning or error free. If you need help locating a trained shop, try https://locate.apple.com
Best of luck with getting this repaired! (But only if it needs it)

How do you clean dust from the inside of a MacBook Pro?

Yeah, on a 2010 MacBook pro, there is no way to separate the keyboard from the top case without disassembling the entire machine. The best way to clean out those keys is to get some compressed air and go to town on it.


Install Mac OS on external drive: disk locked

Of course after hours of trying, I found an answer soon after I posted.

I connected the external drive
From the app store, I found Big Sur and clicked "Get". Because I'd already downloaded the installer, it started after a few moments
I clicked continue and accepted the Ts & Cs
When the "select disk to install" came up, only the internal disk was shown so I clicked the "Show all disks" button
The external disk was also shown, so I selected it
A message said the disk couldn't be used as it wasn't APFS with GUID partition map
I backed out of the installer, ran disk utility, erased the disk and formatted it as APFS with GUID
Ran steps 1 to 4 again, this time the install proceeded
20 minutes later I had a bootable external drive.

The above is far simpler than the MacWorld instructions.


Cannot install macOS Beta version on MacBook Pro July 2019

I found this...
Catalina Link to App Store

Edit:  This link now downloads beta 5.

It may help trigger the search for updates but it didn't fix the issue for me either.

Update:  I ran the App Store link on my iMac that already has Catalina.  App Store opened System Preferences and asked if I wanted to download Catalina.  I answered yes and that downloaded the full installer.

From there I made the thumb drive from the command line and when I booted off the thumb drive it tells me that a software update is required for this Mac and clicking software update tells me that there is no update.

Running the installer from within Mojave tells me that "This version of macOS 10.15 cannot be installed on this computer."

Apparently the laptop is really unsupported at this point.


Crop fails to work as expected on iOS8 Photos app

I can't reproduce that behavior. All kidding aside about handsomeness - I'm getting the expected crop on all "selfie" camera shots.

I've tested on the original iPhone mini and iPhone 5 with iOS 8 so far.

It's almost like a retina bug where it's counting pixels instead of points. Perhaps it's a 2x error that needs to be reported to Apple if you can reproduce it on another device that's the same hardware as yours.

Cannot launch Team Fortress 2 because of some OpenGL error

That's not going to happen. You'll need a newer computer to run games from Steam.

The Powerbook G4 you're trying to use was released in October 2001. Team Fortress 2 was released for macOS in 2010, nine years later. It never supported PowerPC systems, which had not been produced since late 2006.


With Firefox Aurora, Mountain Lion hung - but the mouse still worked

Suspect an issue affecting the WindowServer process (brief edition for power users)

The symptoms you describe are familiar but not commonplace and in my case, not frequent.

Diagnosis – at the time of the problem, if it recurs

Remotely,

sudo sysdiagnose

After you regain local control, you can analyse the end result.

Remotely,

top -o state

Processes that are stuck should be at or near the top.

Is WindowServer stuck for any length of time?

Workaround

If WindowServer is stuck, you might kill remotely –

sudo killall WindowServer

– but this will cause a local log out, so be prepared to lose unsaved changes.

This relatively short answer is tuned to the opening poster's confidence with remote ssh and bleeding edge stuff.

For a more detailed answer, accepted under a similar question where the cause of a problem may be different: Suspect an issue affecting the WindowServer process (long edition)


Turn on FileVault, don't run suspicious applications, don't use public networks too much, etc. I would also suggest you have a look at Little Snitch or HandsOff. These are applications that detect all incoming and outgoing network connections and allow you to block them. Great apps to see what processes are communicating to what servers, and if you see anything suspicious, you can deny the connection.
For Keyloggers I suggest you have a look at this site. It has some useful recommendations.
I don't actually recommend any antivirus for mac. Macs are pretty virus-free: I'd say you are pretty much completely safe if no one hates you, and if somebody does they aren't going to infect your computer with a virus; they'll attempt to hack you, so anti-viruses seem pretty useless on Macs.
As far as I know, Colloquy should automatically mask your IP. I'm not completely sure about this, and I suggest you have a look at websites that talk about IRC security, such as this one. The final option, I'd say, would be to use a proxy.

Last, if you would like a complete security guide to Mac OS definitely have a look at this manual by Apple. It has pretty much all the security options you might encounter on Mac OS X. It's quite long, but a few chapters (4, 5, 8, 9, etc) might prove useful to you.

Hope it helps!

iMac - Airport 'Looking for networks' affects FireWire audio device

Other than disabling the WiFi card entirely, there isn't a documented way to prevent periodic scans with the Mac OS running.

It's possible that just normal interference like when a mobile phone disturbs a radio is affecting the audio signals.  You don't say what Mac hardware you are using, but you could try something as simple as moving the audio hardware further away, or to the other side of your iMac/Macbook etc, maybe even run it through a hub or use a long cable to take it out of reach of the antenna, see if it makes a difference.  Failing that try changing the WiFi channels on your router to see if it helps.

The other issue to consider is perhaps the AirPort card is failing or improperly grounded / connected inside the mac. I have seen the antenna cables pop off when a Mac takes a tumble - so if it's not too much inconvenience or cost, having a technician run a quick test on the airport card and verify all the internal cables / grounding is correct might solve the issue as well.

It's entirely possible with Lion that the airport drivers do different things with AirDrop that Windows drivers don't do and that could conceivably be the cause. It's a long shot, but I've seen this sort of thing before.

How to uninstall an uninstalled app from the App Store?

In the special case of Xcode, the App Store downloads an installer app that you use to install Xcode. Look in /Applications for "Install Xcode.app" and delete that.

When you get Xcode installed properly, if you delete the installer, the App Store won't think it's installed and won't display updates.

Using email addresses in App Store screenshots

According to the App Store review guidelines, you're responsible for ensuring you own all rights to whatever you put in the description or screenshots.  You can put email addresses in the screenshots but, of course, you need to own those addresses.  You also must be prepared for the onslaught of spam and other email those addresses will receive once the address is displayed to the world.

Common sense would tell me that you should blur at least part of any address you display.  You want to show potential customers an accurate representation of what your app can do.  If that involves displaying an email address, I think you're ok and as long as you blur parts of the address I don't believe Apple will reject it.  If the address is something like xxxx@apple.com or xxxx@yahoo.com, then you should expect a rejection, in part because you're implying that Apple uses or endorses your app as well as you're using a registered trademark.  That is in the review guidelines so it's pretty much a guaranteed rejection.

Just make-up an email address and blur the parts you indicated, you should be ok.


Since Mojave isn't officially supported the recovery partition might be missing.
An alternate way to access the utilities without the CMD+R is to create an install usb. To do this first pick which version you want.

I took my iPhone 4 apart and now the display isn't working

I concur with Jan's suggestion, and direct you to iFixit's Installing iPhone 4 Display Assembly. Perhaps if you repeat the procedure, carefully following the instructions in the guide, you can restore the display functionality.

I would also add, at the risk of sounding condescending, that had you done a little research prior to tearing open the device, you would have discovered that the iPhone 4 digitizer is bonded to the outer glass. This was much discussed, and often criticized both because of screen discoloration on new devices (until the "glue" set) and as being anti-DIY repair when the device was first released. Live and learn, I applaud your initiative in opening your device.


Opening Windows 8 through VirtualBox on a Macbook Air

Your question is a little unclear but if I understand you correctly, you can install Windows 8.1 as a virtual machine running within Mac O/S X.

Virtualbox is a good (and free) download that will allow you to install Windows 8.1 inside Mac O/S X. All you need is a Windows 8.1 disk image file (on the PC it's called an ISO for it's file extension) that you purchase from Microsoft or someone who sells Windows downloads and a copy of the Virtualbox installer.

There is an active community that can answer any questions that the documentation does not cover right there on virtualbox.org.

And that should get you started.


Snow Leopard vs. Lion performance: what are the differences?

There's very little difference.

Check out this cnet review it shows the performance of applications like Photoshop, Call of Duty 4 etc. on a 27" 2011 iMac running Snow Leopard & Lion:
http://news.cnet.com/8301-17938_105-20081987-1/snow-leopard-vs-lion-performance-head-to-head/, which concludes:

  For the most part, we found only minor speed variations between the
  two operating systems.


How to open GUI applications on remote machine logged in via SSH on OS X

Try running a local X11 application first. If that doesn't work, reinstall Xquartz and log out and back in again.


The manual contains:
Battery Low The battery level reached a critical level (usually less than 5 percent charged).

This event is currently only handled on Windows hosts and Mac OS X hosts. When this event is generated, VirtualBox will save the state and terminate all VMs in preperation of a potential host power down.
The behavior can be configured. By executing the following command, no VM is saved:
 VBoxManage setextradata global "VBoxInternal2/SavestateOnBatteryLow" 0

This is a global setting as well as a per-VM setting. The per-VM value has higher precedence than the global value. The following command will save the state of all VMs but will not save the state of VM “foo”:
 VBoxManage setextradata global "VBoxInternal2/SavestateOnBatteryLow" 1
 VBoxManage setextradata "foo" "VBoxInternal2/SavestateOnBatteryLow" 0

The first line is actually not required as by default the savestate action is performed.


Yes, I have it running on Lion ( 10.7.2 )


What is the complete upgrade path for Mac OS X version 10.7?

For Mac OS X Lion 10.7, you need to have Snow Leopard (10.6) installed and updated to have the Mac App Store. So yes, if you had a computer still on Leopard 10.5, you would first have to install Snow Leopard, update it to get the Mac App Store update, and then install Lion from the App Store.

You mentioned:

  I know 10.8 is coming out soon).

It's coming out tomorrow! :)
Which is great, considering that Mountain Lion 10.8 allows Snow Leopard 10.6 and higher Macs to upgrade directly!

I've never had any problems upgrading an OS, although I usually run a backup before just in case (and it's a good idea).

I can't find an official Apple article for upgrading from Leopard 10.5, but I'll edit this post if I do.  I would assume that it is as simple as following the directions given when inserting a Snow Leopard install disk.

It is important for the XQuartz app to inherit a proper PATH from launchd. The path of the systemwide launchd is /usr/bin:/bin:/usr/sbin:/sbin by default; you can check its value by running

sudo launchctl getenv PATH

If is not as expected, it has most likely been set by a command in /etc/launchd.conf. (This file contains commands in the format expected by launchctl; see the manual page for the latter.)

When you log in, launchd forks a process that becomes the per-user launchd. This inherits the environment from the system launchd, but its environment can be further altered by the commands in /etc/launchd-user.conf and the contents of ~/.MacOSX/environment.plist. Look in these places for alterations to the PATH environment variable, and make sure it at least contains the four paths mentioned above. You can check its value by running

launchctl getenv PATH

(note: no sudo). While experimenting, you can change the environment of your launchd by running

launchctl setenv PATH /usr/bin:/bin:/usr/sbin:/sbin

and then stopping and restarting XQuartz.app. But once you have a solution that works, use either one of /etc/launchd-user.conf or ~/.MacOSX/environment.plist to set the appropriate value permanently. Use the former for all users, and the latter if it's a personal preference.


Why does Xcode 4.1 Installer ask me to quit iTunes if iTunes isn't running?

This is a widely-reported bug in some App Store installers. It sees the iTunesHelper process and displays this error, even though that process is not controlled by the user.

You can open Activity Monitor (in /Applications/Utilities), find the process and kill it with the Quit Process button in the top-left corner.

You can also instead open Terminal (also in /Applications/Utilities), enter the following line and press enter to kill it.

killall iTunesHelper


iPad iOS 6.1.3 suddenly very weak wifi signal

I would ask if you can definitely link the introduction of the poor signal to the time immediately after installing the upgrade.  They may be linked, they may not.  If you think there is a link, then I would advise backing up the iPad, and reapplying the OS update via a full restore, thus essentially imaging the entire OS from scratch rather than relying on the OTA upgrade from 6.1.2.

After a re-image, then to rule out any configuration issues, try to connect to the WiFi source without restoring your data.  If it works, then perform a restore and check again.  If it's still not working, then my hunch is that maybe you have accidentally caused the wifi antenna connection to disconnect internally - serious question, can you identify any faint rattle type noise if you shake it, particularly in the bottom right where the cable connects.


No, not as such.

You might have damaged the headset or the plug on the Android phone inadvertently, but it is not because you have plugged the headset into an iPad.


Multiple "copies" of audiobooks in iTunes

Through trial and error, found the source of the problem and a solution that consistently works for me. Explanation and screenshot follows.

Source of the Problem

The Sorting tab has three groups you can sort on: title, chapter, author. If the text in the specific field is disabled, then there will be duplicate copies of a given audiobook.

Note: The words "disabled" (for gray text) and "enabled" (for black text) in this context are my own and may or may not be the same terms used by Apple devos.

Solution

Simply retype the disabled (gray) text.

The screenshot shows an example where the "chapter" field was disabled. When I retyped "Mixed," the text changed to black. Clicked OK, and the duplicate audiobooks disappeared.

The same solution worked for me when title or author were disabled. Note that the "sort as" field is ok in gray.

MacBook Pro Retina and 4k monitor (Samsung U28D590D) now showing "scaling options" in display

@jorgen.ringen, I am facing the same issue with a 13" 3Ghz Macbook Pro 11,1 (mid-2014). The reviewer in 9to5mac from the link you posted states that the HDMI input ports will only do 4k at 30hz, so the only solution (as he also states) is to purchase a miniDisplayPort to DisplayPort 1.2 adapter or cable. I went for the cable and am currently awaiting its delivery.

I played with SwitchResX lots. Several threads on the internets suggest overriding the EDID in an attempt to fix the Television=yes in System Report problem, using Picture in Picture mode and running the display off of two cables. Neither of which is very satisfying to me, as its either a) PIP is not for every day use or b) requires plugging two cables, making it further more difficult to mount my machine on a desk and take it off.

The DisplayPort cable will hopefully do the trick when it arrives. Meanwhile, I noticed there is some kind of firmware update on the product page of the monitor. It requires a Windows machine, so I have not yet tried it. I can't find a way to see the current firmware version in the display menu either, but Samsung state that its a "compatibility improvement update" or some such. There is no changelog as to what changed since the previous version, or any explanation as to how that potential update might occur. To my knowledge, HDMI 1.4 supports Ethernet and maybe thats how the update takes place. If you have a Windows machine around, give it a try and report back please.

P.S. Unfortunately, the stupid SE comment policy will not allow me to post this as a comment. Whatevs.


Airdrop Alternative for Windows/Mac/Linux?

Have a look at Transfer on Lan - it's not as full of hardware encrypted, peer to peer mesh network goodness as AirDrop, but it's the closest stand in for AirDrop that I've seen in a cross-platform client.

http://code.google.com/p/transfer-on-lan/

It uses a normal network as opposed to building up a secure temporary network, but other than needing java, it's pretty easy to implement.


If a Wi-Fi and a USB-cable is connected at the same time, will my network be more stable and faster?

MacOS can have multiple network connections, via WiFi, Ethernet, Thunderbolt and indeed USB.

Normally, one network takes preference over another: if the protocol can't be established on one network, it will look at another. In this way, it's possible to have Internet, file sharing, and other network devices like printers all on separate connections and networks.

Your internet connection will come from only one network. You can't combine two separate network connections and use both simultaneously.


How can I replace the Mac Mail icon in Mac OS X 10.11 El Capitan?

The proper way is to:

boot your Mac to Recovery Mode by holding CMD+R at startup
Go to Utilies and Terminal in the menu
Type csrutil disable and Enter
Restart normally and change your Icon

Repeat the procedure to re-enable System Integrity Protection (SIP or Rootless) but this time, enter csrutil enable

that's it !


How do I set my external monitor so that my gestures won't activate spaces on the external?

Control over spaces and external displays is fairly limited in Lion. At the moment what you're looking for isn't possible.

One "space" is really the combination of your MacBook and external display, they can't be separated. Because of this, the number of spaces on your external display will be exactly the same as the number on your MacBook display, and you can't exclude one display from switching spaces or activating Mission Control.


"There are stopped jobs." when exiting bash

If you have jobs that are stopped (with CTRL-z) or happened to be in the background but are stopped waiting for input, you can see what's there with the 'jobs' command.

If you only have a job, then a 'fg' will bring it to the front for you to interact with it or kill with a 'CTRL-c'. If you have multiple jobs, you can bring individual or specific ones with 'fg '.


Look at your hosts file. You can find it by clicking on the "Go' menu in the Finder and select "Go to folder..." then type "/etc/hosts". Copy the file on to your Desktop and open it with Text Edit.

You'll see the following lines at the top of the file :

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0 localhost

If you have others lines underneath, look for the domain "svenskadomaner.se" in a line such as 127.0.0.1 svenskadomaner.se. If you find a line like this, then your Mac redirects the domain to your localhost (your Mac) and of course it won't find the server. This is the technique to block a website on a computer. So delete the line, save the hosts file and replace the "/etc/hosts" file with the one that is on your desktop.

Then you can try again to go the website ;-)

Edit : It's possible that you don't have "127.0.0.1 svenskadomaner.se" in the file but something like "127.0.0.1 IP Address" where IP Address is the address of the servers of www.svenskadomaner.se.


Why am I not able to run a website which ‘requires javascript’

The problem is that the web site is simply broken.

When your browser connects to a web site it sends along a so called "user agent"-string, which specifies which browser, browser version and operating system, you're using.

That specific web site uses that information to only show the real page to user agents that it allows. Others will be shown that incorrect page telling you to enable Javascript - which is misleading.

In order to access the web site from an iPad, you'll need to a use a browser that allows you to change your user agent. That is not possible with the standard Safari.

If you're on a Mac, you can enable the Developer menu in Safari system preferences. From the developer menu, you can choose "User Agent => Google Chrome - Windows", and then you get to the real page.


macOS doesn't do 'alt-codes', that's a Windows feature.*

Simplest solution might be to use the Keyboard Viewer, accessible from the Menu Bar once enabled in: System Preferences > Keyboard > Keyboard

On a UK keyboard they're accessed by pressing  Shift ⇧

*From comments:
They can be made to work, though I feel they're more effort than really needed ;)
System Preferences > Keyboard > Input Sources > Plus sign > Unicode Hex input. After you choose it, you can do Option then 003C, it'll show the < symbol.

Here, un-check the option "Ignore the integrated trackpad when a wireless trackpad or mouse is connected"... That's all!!!

I have my OS in Spanish, therefore I am not sure about the translation for the English version, but I really hope that this can help to solve your problem.

Best regards!!!


Fusion Drive acts as an extension to the installed HD, it is not a cache. If you would use a RAM disk as the SSD part for your DIY Fusion Drive you would loose the data stored in the RAM part whenever the system shuts down.
