iMac Crashes After 11.2.2 Upgrade

Since I upgraded my iMac to 11.2.2, I've been experiencing hard freezes daily. The only option is to unplug the power cord. I've 'reset' the SMD by unplugging the power cord for 15 minutes, then plugging it back in for 5 seconds before booting up. Is anyone else experiencing this issue?

Hi Mufashi,


I believe we need to proceed with an EtreCheck report. EtreCheck is a useful app to diagnose issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:


  1. Go to the Mac App Store and search for "EtreCheck."
  2. Download it. It is a free and trusted app; as it is on the Mac App Store, and only trusted apps can be submitted
  3. Run the report, and put it in a post, as seen here - https://discussions.apple.com/docs/DOC-250000211. We will then examine the report for issues in your Mac.
  4. Open EtreCheck, then go to the name "EtreCheck" in the top left corner > "Preferences" > "Privacy" > turn on "Allow Full Access to Startup Drive."


Also run Apple Diagnostics -  Use Apple Diagnostics to test your Mac - Apple Support Please post the Reference code when done.


Please post results of both!


Cheers,


Jack
