techno.rentetan.com – “Fine, I’ll do it myself,” as Thanos once stated. The new macOS 12.1 from Apple is a blast. For the first time, you may now share your screen and other material with your pals on FaceTime video chats on macOS, as well as Hide My Email and Apple Music Voice Plan. It’s possible that you won’t notice this update at all if you’re using an M1 Mac. What’s going on?

It’s a wonder why macOS 12.1 won’t appear on M1 Macs

We don’t know what’s going on at this point. For some reason, M1, M1 Pro, and M1 Max users are experiencing difficulty downloading or even seeing the 12.1 update in System Preferences. Even after downloading the whole macOS Monterey installer from the Mac App Store, Bradly Chambers of 9to5Mac couldn’t get the update to operate..

9to5Mac commenter swoops in and provides an answer. According to commenter Jonlon, the 12.1 update was not showing up in System Preferences on his M1 Mac mini and M1 Max MacBook Pro. Finally, Jonlon came up with a six-step strategy for Mac users to get the update to appear and download:

  1. Open System Preferences > Software Update. Leave the window open after confirming that no updates are available.
  2. Go to Applications > Utilities > Activity Monitor.
  3. Go to the View > All Processes menu and choose it.
  4. In the search bar, type in ‘updatebrainservice’. Select it, then click Force Quit. You can also try “com.apple.NRD.UpdateBrainService” instead if that doesn’t help.
  5. System Preferences should show the 12.1 Update. Update now by clicking on the Update Now button.
  6. Force-quit the com.apple.MobileSoftwareUpdate.UpdateBrainService again using Activity Monitor to restart the download. Alternatively, you may need to forcibly terminate the service “com.apple.NRD.UpdateBrainService.”

No one, even Jonlon, can explain exactly how or why this particular procedure results in an update, but for the time being, it does. As of this writing, the best answer is to follow this procedure if you’re having difficulties locating the update on your M1, M1 Pro, or M1 Max Mac.
