User level: Level 1 (4 points)After updating my MacBook Air M4 to macOS 27, it gets stuck on the Apple ID login screen during setup and won't proceed. It also freezes when I select "Set up later." I tried reinstalling the OS via the recovery menu, but that didn't fix the issue, and Safe Mode didn't help either. What should I do?

Since it also freezes when you choose “Set Up Later,” I wouldn’t assume the Apple Account itself is the problem.
I’d shut the Mac down, disconnect any accessories, then start in macOS Recovery and run Disk Utility > First Aid on the startup disk. Apple recommends repairing the startup disk when macOS has persistent installation/startup problems.
If that finds nothing and you’ve already reinstalled macOS from Recovery, I’d contact Apple Support before erasing the Mac. Don’t erase it unless you have a current backup of anything you need to keep.
Apple’s troubleshooting steps are here: If an error occurred while updating or installing macOS - Apple Support
