Question: Trying to revive a mid 2011 iMac, keeps crashing after clean installs

Hi all,


First of all, thank you for reading this post and attempting to help. I am trying to help my father-in-law in resurrecting his mid 2011 27 inch iMac. He has been experiencing a problem where his computer will frequently reboot randomly when he is doing even the most simple of things like browsing the web. I read up a little bit on the issue and can't seem to figure out what is going wrong. I helped him to do a clean install of high sierra the other day and we have thus far only installed chrome and adobe's CC. While we were in the process of installing Illustrator the computer crashed again and gave us this Panic Report. I'm hoping someone can help me decode the problem so I can get him back on his merry way editing his photos.

First thoughts are: HDD is dying and/or defective memory module.


A Troubleshooting Procedure that may Fix Problems with macOS El Capitan or Later

You should try each, one at a time, then test to see if the problem is fixed before going on to the next.


Be sure to backup your files before proceeding if possible.


  1. Shutdown the computer, wait 30 seconds, restart the computer.
  2. Disconnect all third-party peripherals.
  3. Resetting your Mac’s PRAM and NVRAM
  4. Reset the System Management Controller (SMC)
  5. Reset your Startup Disk and Sound preferences.
  6. Start the computer in Safe Mode. Test in safe mode to see if the problem persists, then restart normally.
  7. Use Apple Hardware Test to see if there is any hardware malfunction.
  8. Repair the disk by booting from the Recovery HD. Immediately after the chime hold down the Command and R keys until the Utility Menu appears. Choose Disk Utility and click on the Continue button. Select the indented (usually, Macintosh HD) volume entry from the side list. Click on the First Aid button in the toolbar. Wait for the Done button to appear. Quit Disk Utility and return to the Utility Menu. Restart the computer from the Apple Menu.
  9. Repair permissions on the Home folder: Resolve issues caused by changing the permissions of items in your home folder.
  10. Create a New User Account Open Users & Groups preferences. Click on the lock icon and enter your Admin password when prompted. On the left under Current User click on the Add [+] button under Login Options. Setup a new Admin user account. Upon completion log out of your current account then log into the new account. If your problems cease, then consider switching to the new account and transferring your files to it - Transferring files from one User Account to another.
  11. Download and install the OS X El Capitan 10.11.6 Combo Update or 10.12.6 Combo Update or Download macOS High Sierra 10.13.3 Combo Update as needed.
  12. Reinstall OS X by booting from the Recovery HD using the Command and R keys. When the Utility Menu appears select Reinstall OS X then click on the Continue button.
  13. Erase and Install OS X Restart the computer. Immediately after the chime hold down the Command and R keys until the Apple logo appears. When the Utility Menu appears:
  1. Select Disk Utility from the Utility Menu and click on Continue button.
  2. When Disk Utility loads select the drive (out-dented entry) from the Device list.
  3. Click on the Erase icon in Disk Utility's toolbar. A panel will drop down.
  4. Set the Format type to APFS (for SSDs only) or Mac OS Extended (Journaled.)
  5. Click on the Apply button, then wait for the Done button to activate and click on it.
  6. Quit Disk Utility and return to the Utility Menu.
  7. Select Reinstall OS X and click on the Continue button.

If none of the above helps then make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple.
