Hello,

I am having an issue updating my 2020 M1 MacBook Air to OS 12.1. When I tried updating, I got a message saying that only owners can update, (which I thought was a bit strange, considering I am the owner). Restarted Air, then tried to update again, only to say that it was up to date,(12.0.1)

I also have a 2020 Intel iMac, was able to update to 12.1 with no problems.

This is not the first report that I have heard of this issue...

Add Terminal.app to >System Preferences>Security&Privacy>>Privacy>"Full Disk Access" folder using the +/-

Then from Terminal copy & paste:

sudo softwareupdate -i -a -R

this will bypass the secure token/owner check from the Software Update pref pane—

-i Install

-a All appropriate updates

-R Automatically restart (or shut down) if required to complete installation)

The Monterey 12.1, a major point update to macOS. The update is ~ 2.36GB

I encountered this when trying to run an update on an external macOS install. As it turned out, Monterey updates can only be installed on designated start up disks. I was getting the same message.

Try going to System Preferences->Startup Disk, unlock access, and set the internal drive as a startup disk again and reboot and see what happens.

It is possible that somehow the Mac may have "forgot" that the internal drive was the designated startup disk.

Not sure if this will work, as so many other very good suggestions have already been offered.

Terminal and this command without Quotation marks  " softwareupdate --list-full-installers " What is the output.?

If Monterey 12.1 is seen - good.

Again without Quotation marks " softwareupdate --fetch-full-installer --full-installer-version 12.1 " which will pull the Full Version of 12.1 approx. 12.17 GB size.

I would stop there and make a TM Backup first. Then, Copy the new " Install Monterey " in applications folder to External Drive.

Restart in Safe Mode and then run the Installer.

Welcome. Okay last thought. Copy this link and paste it into Safari's address field, hit return. Run the package which should install "Install macOS Monterey" into the Applications folder. Then run that.

InstallAssistant.pkg

Just suggested this to another person: try to repair disk under Disk Utility. Restart, hold down command+R to get to recovery utilities; pick Disk Utility. Choose verify disk or repair.

Restart when complete then see if the update will work.

FWIW, there have been some reports around the web that some M1-based Macs are not getting the 12.1 update. On the other hand, I updated my M1 MacBook Air yesterday without a problem. I don't think the cause is known at this time.

Doesn't work for me:

Mottis-mini-M1-mac:target $ sudo softwareupdate -i -a -R

Mottis-mini-M1-mac:target $ 

Where obviously update exists (I run 12.0.1 and System-PReferences pane of Sofware-update offers 12.1 to me).



Doesn't work for me either:

Mottis-mini-M1-mac:target $ sudo softwareupdate -i -a -R

So what's next? I do not wish to reinstall the OS now -- both it takes ages to download and install, and I'm not sure it'll cure the problem. This is my development work Mac...

You're welcome.

Good work. 🎅
