panic! unable to find driver for this platform "ACPI"

Ran a system update last week and the computer has booted with this kernel panic message (see attached). I have tried to reboot holding control+R and also have tried zapping the PRAM but nothing is working. Not sure what to try next. Can you help?

Unfortunately, Im not sure what system was running.

iMac (21.5-inch, Late 2012), null

Hi Cambb,

Thank you for contacting Apple Support Communities. Based on what you stated, it seems like you are having a kernel panic. It looks like you have already done some troubleshooting. I would recommend you read these articles and use them to help troubleshoot the issue.

If you can't start up from macOS Recovery

Newer Mac computers and some older Mac computers automatically try to start up from macOS Recovery over the Internet when unable to start up from the built-in recovery system. When that happens, you see a spinning globe instead of an Apple logo during startup. To manually start up from macOS Recovery over the Internet, hold down Option-Command-R or Shift-Option-Command-R at startup.

If you still can't start up from macOS Recovery, and you have a Mac that is able to start up completely, you might be able to create an external Mac startup disk to start up from instead.
