If you're having difficulty finding or installing updates:
Updating macOS can be a real chore sometimes, especially if you get stuck in an update loop because there isn’t enough free space. Some users started the update but found themselves stuck in this “boot loop” after it failed, returning to the update installer page every time their Mac booted up again. I own a MacBook Pro 13 inch with 128gb and this update was stressful. I had to move basically everything on Mac to an external ssd including the Big Sur installer. Whatever I moved the storage was not updating. I almost gave up but then I restarted my Mac and finally it showed there was enough space available.
Most of the time, macOS should be able to resolve these issues gracefully, but occasionally it may cause your Mac to lock up halfway through the update. If your Mac encounters difficulties when downloading or installing the latest release, don’t panic! In this article, we share seven fixes that can fix your frozen Mac and get it back on track.
