Hey Everyone, this is a fun one. Apple's 2011 Edition Macbook Pros had this awful underlying fault with the AMD GPU (graphic card) that caused it to fail, and thus your Mac wouldn't boot. It was such a prevalent problem that Apple issued a recall, but in classic Apple fashion they only "fixed" it if you experienced the failure, actually they only replaced the logic board with another having the same underlying GPU fault -- just to buy time to get out of the warranty period. Thanks Apple. 

What the problem looks like:

• Your Mac boots to 3/4th the way and shuts down, restarts, hangs on a grey screen. 
• Your Mac displays pink or green lines in the display image. 
• Your Mac randomly shuts off and reboots. 
• Your Mac runs extremely hot to the touch.
• Your Mac needs many tries to boot up.

Here's the Fix:

1. Reset the SMC.
   1. Shutdown the Mac.
   2. Plug it into power.
   3. Hold down for five seconds then release: Left Shift + Ctrl + Option + Power
2. Reset VRAM.
   1. Boot the Mac and hold down the keys: Command + Option + P + R
   2. Continue holding the keys till you hear two chimes. 
3. Shutdown / power down the Mac.
4. Boot into Single User Recovery, hold keys during boot: Command + R + S
5. Disable SIP, type and hit return: csrutil disable
6. Disable AMD GPU, type and hit return: nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00
7. Enable Verbose Mode, type and hit return: nvram boot-args="-v"
8. Type and hit return: reboot
9. Boot into Single User, hold keys during boot: Command + S
10. Mount Root Drive, type and hit return: /sbin/mount -uw /
11. Make Directory for bad AMD Extension, type and hit return: mkdir -p /System/Library/Extensions-off
12. Move the AMD Extension, type and hit return: mv /System/Library/Extensions/AMDRadeonX3000.kext /System/Library/Extensions-off/
13. Update the change, type and hit return: touch /System/Library/Extensions/
14. Type and hit return: reboot

At this point the Mac will restart twice. First, it will run a bunch of text past, this is normal and will only happen once. It will chime and reboot again and run different text past, this is also normal and will happen on every reboot (it's quick). Finally, the Apple logo will appear and the boot will finish. Your mac should work normally now. 

You're welcome. If you need help, we charge $25 for the fix, done in 20 minutes. Call or text us.

Every now and again (very often) we find stock Apple Fusion drives that are acting up. You might want to tear the fusion apart and put them back together again to know it's formatted correctly.  Here's how you do it:

Split Fusion Drive

• Boot into the recovery partition -- From a powered down mac, power it up and hold the command-R keys together before the chime, release when you see the apple logo. The boot will be slow, please wait...
• From the top menu select "Utilities" and select "Terminal."
• In terminal type and hit return: diskutil apfs list
  • ​This will list all the apfs disks connected to the Mac. 
• Look for the word "Fusion" and note the disk# eg. "disk0"
• Type the command and hit return: diskutil apfs deletecontainer disk0
  • ​**Note the disk# should be the one you noted from the list. 
• Terminal will now spilt the fusion disk into its two parts.

Repair / Build Fusion Drive 

• In terminal type and hit return: diskutil resetFusion
  • Terminal will show you the two internal disks and ask if you want to proceed.
• Type and his return: Yes
• The fusion drive will be rebuilt. You're ready to reinstall macOS or whatever you want.

Ran into this problem on a few macs. The scenario is that you've uninstalled teamviewer on macOS catalina and now your mac won't boot. Instead it give you an error that reads: "Unrecoverable Error. SecurityAgent was unable to create requested mechanism TeamViewerAuthPlugin:Start.

Basically it's a file that the OS is looking for to boot and it can't find it. Solution below:
​
UPDATE! 5/1/20

AuthDB Removal:

1. Make sure your Mas is powered off by holding the power button for 10 seconds.
2. Start into macOS Recovery by holding down Cmd-R when booting before the chime, until the apple logo.
3. Open Disk Utility -- found in the upper utility menu option.
4. Check the left source list and remember the name of your disk. For Macs running Catalina it's the Disk that does not end in "- Data". It's usually "Macintosh HD." *consider taking a photo to remember. 
5. Click to select the disk in the sidebar.
6. Click the "Mount" button in the upper right. If you see the word "unmount" skip this step.
7. Quit Disk Utility.
8. From the top menu bar click Utilities > Terminal.
9. Type the command and hit return:      rm "/Volumes/Macintosh HD/var/db/auth.db" 
   1. ​​NOTE** There is a space after rm
   2. NOTE** The quotes are part of the command.
   3. NOTE** If "Macintosh HD" is not the name of your disk, replace that part with the name of your hard disk from step 4, including spaces, written exactly as displayed in Disk Utility. 
   4. NOTE** once you enter the command hit return to submit the command. 
   5. NOTE** if the terminal doesn't present an error and is waiting for a new command, it's successful.
10. Restart.
11. ​If you receive an error review the steps carefully again.

• Click the profile in the list to the left titled "Admin Prefs" and click the minus "-" button at the bottom to remove.
  
• Then open the terminal. 
  
• Enter: sudo profiles -D 
• Enter your password when asked.
• Say "Y" to approve if asked. 
• Restart your Mac.

That should remove the annoying weknowac search page in Safari. If you have the same problem in Chrome, click here for the directions to remove it.

Are you getting those annoying Mojave update notifications constantly? Stop them forever. 

• Open the terminal and enter: softwareupdate --ignore macOSInstallerNotification_GM
• Hit return

They are gone. Enjoy. You're welcome. ​

The most persistent malware we've seen is the Smart Search weknow.ac. This malware has the usual launch agent, browser extension, install files, but this one also changes the chrome profile. This is some pretty serious stuff that get's deep at the heart of Google Chrome, so even when you remove the files, the malware search page persists. Don't worry! We'll fix this together. 
​
How do you know if you have this particular Malware:

1. Your search engine on your browsers says "safe search."
2. You cannot change your browser homepage, it simply returns to the safe search.

Remove is pretty simple. Go screw yourselves malware jerks. Here's what you do:

• Run the latest trial version of Malwarebytes to easily remove all the instances on the Mac (then uninstall Malwarebytes by clicking help>uninstall ~~ you don't need to buy the subscription).
• In Google Chrome, go to
  • preferences.
  • click "advanced" at the bottom.
  • click "restore setting to their original defaults" (at the bottom).
• Next, open terminal. Enter each line, hit return, and repeat with the next line (enter password if needed):
  • defaults write com.google.Chrome HomepageIsNewTabPage -bool false
  • defaults write com.google.Chrome NewTabPageLocation -string "https://www.google.com/"
  • defaults write com.google.Chrome HomepageLocation -string "https://www.google.com/"
  • defaults delete com.google.Chrome DefaultSearchProviderSearchURL
  • defaults delete com.google.Chrome DefaultSearchProviderNewTabURL
  • defaults delete com.google.Chrome DefaultSearchProviderName
• Next quit and restart Google Chrome. 

The end. You're welcome. ​ Oh, here's the directions to remove it from Safari too.

Apple Mail has been a finicky bit of software since its inception. Some love it, some hate it. One problem we've seen recently in V10 with High Sierra is that emails display [the usually] hidden HTML code. This can be frustrating. Some have 'solved' it using Apple Mail's built-in "rebuild" option, but the problem seems to return pretty quick.  Here's how you can solve this issue and other weird mail issues too.

1. Open System Preferences > Internet Accounts> iCloud > UNCHECK "Mail"
2. Inside Apple Mail > System preferences>  disabled Junk mail filtering. 
3. Inside Apple Mail > Export your local mail to keep a copy safe: Highlight the mailbox in the list on the left and click "Mailbox," then in the upper menu click "Export Mailbox," then choose a place to save the folder. Repeat this for all the mailboxes you want to keep safe. 
4. Quit Mail.
5. Delete folder: ~/Library/Mail/
6. Delete ~/Library/Containers/com.apple.mail
7. Launch Apple Mail
8. Re-Enable iCloud Mail, reverse step 1.
9. Import each mailbox that was deleted in step 4. Inside Apple Mail Click "File" then "import mailbox." Select the folder of all your mailboxes that you saved and import. 
10. Re-enabled rules and junk mail filter (if you want).

You're welcome.

The java on your mac can easily become outdated. Apple doesn't love java, so the auto tools to "update" it often don't work. Here's how you can check which version you're currently on, and how to remove it. 

Note: the current version of Java JDK is V10. (8/23/18) found here.
Check the current version:

• First open the terminal on your mac. 
• Enter this java -version
• It will spit out some info, look for:
  • java version "1.6.0_65" . <--version 6
    Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468-11M4833)
    Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)

Uninstall Java:

• In the Terminal window Copy and Paste the commands below:
  sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin 
  sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane 
  sudo rm -fr ~/Library/Application\ Support/Oracle/Java

I like the stable Java Version 8. Found here.

You're welcome. ​

Super fast one. You lost your notes in the notes app. You have a backup (hopefully), here's where you go to retrieve them:

/Users/[youruserfolder]/Library/Group Containers/group.com.apple.notes

Simply copy the folder "group.com.apple.notes" from your backup to the same location on your Mac.
Boom, notes are back.
​You're welcome. ​

There are lots of long blogs about how to do this. Some are written for the beta version of High Sierra and are wrong. Here's the quick and dirty on trashing your APFS disk in High Sierra and go back to HFS. 

Why?
APFS is brand new disk partition type that Apple introduced in High Sierra. Although it has some benefits, I don't care for it. Anything that apple releases that is brand new, be wary, there are usually issues with it. Also, if you're a mac tech reading this, upgrading OSes or converting from HFS to APFS to solve performance problems is not a solution. If you need help understanding why, email me. 

***WARNING: THIS WILL DELETE THE CONTENTS OF YOUR HARD DRIVE. MAKE A BACKUP***

FIX:

• boot into the recovery partition by holding command-R during boot.
• click utilities in the top menu. 
• select terminal.
• type and hit enter: diskutil list
• you'll see the list of all the drives. look for "APFS" then the disk identifier to the right, something like "disk0"
• type then hit enter: diskutil apfs deleteContainer disk-identifier-here

That's it. You can now re-install, re-store, re-image to your HFS disk however you like. You're welcome. ​

if you've goofed around and tried to change your user name though the advanced settings in your mac, you may have ended up with your user switching back to a standard account. if you only started with one account, then you've left yourself with no admin account. Aaaand you can't change anything. Here's is what you do:

• reboot your mac
• hold command-S before you hear the chime
• you'll see a bunch of verbose text fly past. when it's done...
• enter: mount -uw /
• hit return
• enter:  rm /var/db/.AppleSetupDone
• hit return
• hit control-D on the keyboard to restart.

Your mac will now boot and start the setup wizard again. Go ahead and create a new admin user. 

​You're welcome. ​

Here's a quick one. 

The Situation: you have a million screenshots on your desktop. You curse mess and want to take control. Great! Set a folder to keep all the screenshots automatically, rather than turning your desktop into unwieldy monster.

The Fix: 

• make a folder on your mac where you want to save your screenshots. Name it whatever you want. 
• open the terminal.
• paste in this command: defaults write com.apple.screencapture location
• don't hit enter yet. after the the word "location" enter a space then drag and drop the new folder you created for the screenshots into the terminal window. That will auto fill the path to the folder, and should look something like this (if the folder is on the desktop titled "Screenshots"): 

defaults write com.apple.screencapture location /Users/yourusername/Desktop/Screenshots​

• now hit enter!
• next, enter this command and hit enter to reset the system to activate it: killall SystemUIServer

That's it! Now when you take a screenshot it will be saved to the folder you created rather than the desktop. You've tamed the beast. Pat yourself on the back. You're welcome.

The MacOS setup assistant will only run once. If you've created a user and you're unhappy with it, or you want to migrate another user over you might want to reset the OS so the SetupAssistant runs again on next boot. The setup assistant differs from the Migration Assistant by allowing you to choose a specific restore point from a time machine, rather than just the last backup. This is great if you need to go back to a stable OS before you had problems. Here's how:

• Launch Terminal from the Utilities folder
• copy in: sudo rm /var/db/.AppleSetupDone
• Enter your password.
• Restart your mac.

If you lost your admin access, you can do this process through the Safe Boot (thanks commenter*):
1. Boot into Single user mode (cmd+S)
run the following commands:
mount -uw /
rm /var/db/.AppleSetupDone
reboot
On next reboot the system will start the Setup Assistant again. You're welcome. ​

I'll keep this short and sweet. Malwarebytes has for many years been the go to tool for Mac users to easily find and remove malware from you Mac, FOR FREE. Recently they released version 3.0 which is now a subscription based model and only runs in a trial mode. They clearly went the route of building a user base with a free tool then switched it on us. 

Welp, here's the last FREE version of Malwarebytes for Mac that will remove malware for FREE! Of course, don't accept the upgrade if prompted to do so. Enjoy. You're welcome. ​

This is going to be a quick fix. I've encountered a few clients that have a rare problem where they try to log into their iCloud (via system preferences) or log into the App Store and they are greeted with an error stating "This action cannot be completed. Try again." 

You have bad system permissions. Why? Looks like it's associated with an OS update. 

Fix:
Open terminal and paste in each line separately (3 lines), hit enter after each one, then enter your password. Line two and three wont prompt for your password after you've entered it into the first line. 

1. sudo mkdir -p /Users/Shared
2. sudo chown root:wheel /Users/Shared
3. sudo chmod -R 1777 /Users/Shared

Restart your mac. iCloud and App Store will work. You're welcome. ​

What is this? "Cannot open migrated library The content of the iPhoto Library "iPhoto Library" has already been migrated to Photos. Open Photos to view your library or use a compatible version of iPhoto to open this iPhoto Library."  I'm not going to show you how to open this library in iPhoto, there are many other guides online, I'm going to show you how to run the migration to Photos again. Why?

• Your initial migration was halted, stalled, failed. (Power outage, liquid spill, OS crash, cat drama, whatever).
• Photos has missing photos, empty photos, videos that don't play. 
• You want to move the library to another mac and convert to Photos again.

If for any reason you're trying to rerun the migration here's what you do:

• Right click the iPhoto Library you want to re-migrate.
• Click "get info." 
• Open the arrow for "Name & Extension."
• Remove the word "migrated" from the file name.
• Close the window.
• Open the library again and Photos will start the migration over again. 

Why didn't these simple instruction exist on the internet? IDK. You're welcome. ​
