Fixed error updating to macOS 12.1 on Mac with M1
According to some users, the affected models are Macs with an M1 chip. That is, MacBook Air and MacBook Pro M1, Mac mini M1, iMac 2021 and MacBook Pro 2021. In my particular case, I have not encountered any issues updating to macOS 12.1 on a MacBook Air with M1. If this is your case, to solve it you must follow these steps:
- Open System Preferences> Software Updates. If you encounter the problem, you will not see the update.
- Without closing Preferences, go to Applications> Utilities> Activity Monitor.
- In Visualization, choose All Processes.
- Search for “com.apple.MobileSoftwareUpdate.UpdateBrainService” without the quotes, select it and force it to close.
- Monterey 12.1 update should now appear in Updates, go back and reopen this menu if it does not appear.
- If the update does not download, force quit the same process we saw before.
