- A number of people are reporting that installing macOS Monterey is causing their Macs to refuse to start.
- Impacted machines include both portable and desktop Macs.
Apple's recent macOS Monterey release had something of a troublesome beta program for various reasons, but things aren't improving now that it's available to everyone. A growing number of people are taking to social media and Apple's own support forums to report that their Macs refuse to start after updating to the company's latest big release.
More than ten different Apple Support Communities threads, first spotted by MacRumors, highlight the issue. People have been tweeting about their problems as well, all with the same theme — updating to macOS Monterey caused their Macs to no longer power on. It also seems that the issue only crops up on older Macs running Intel chips. If you're using a modern M1 Mac you should be good to go.

@AppleSupport @Apple this is not the way a simple OS update should go on a Mac. On my 50th restart with some sort of incremental install of #Monterey and a dead iMac. Can’t even restore from TM because I can’t even get to the migration app. Crazy@AppleSupport @Apple this is not the way a simple OS update should go on a Mac.

One Reddit user sums things up pretty well when saying that their Mac is now "just dead."
Anyone who is experiencing issues trying to update to macOS Monterey should reach out to Apple Support for assistance. However, one support document might offer some relief.
I'd still suggest reaching out to Apple in the first instance, especially if your Mac is covered by AppleCare.
