Monterey update rendered my iMac useless
Updated to Monterey from High Sierra, checking all the requirements; my late 2015 iMac was on the list, I have over 100GBs of free space, let’s do it! Downloaded it. Computer restarts -gets stuck on black screen Apple logo ‘less than one minute remaining’ -stuck there for hrs. Tried ’Safe Mode’ start up. Reinstalled ’High Sierra’ then hit with ‘MacOS could not be installed on your computer’. Returned to safe mode, go to Disk Utility - use Disk First Aid, says it’s done. Try again to install ’High Sierra’. Once again ‘could not be installed…’ WTF? All of this because I wanted to update my OS? This is outrageous. Help is appreciated.
MacBook Pro 15″, OS X 10.10
