I accidently changed ownership of "/" to my user. Now i cant run basic tasks and recovery isnt an option. PLZ help.

Hello,

My system is a 2020 M1 Macbook Air running MacOS 15 Beta 7

Without going into too much details, I ran "sudo chown -R user1 /" and allowed it to run through-- some files and folders didnt get affected due to permissions but for the files that got their permissions changed--I cant do basic things when logged in as user2 or the root user.

For example: sudo command with anything as the shell would hang, or another thing is the system would get stuck at almost half way into verifying whatever .dmg or .pkg I would be trying to install. A Get Info look at /usr/bin/sudo shows that the admin and everyone groups have no access so I think thats why I couldnt use sudo.

What options besides booting into recovery to reinstall do I have to remedy this? Because due to a faulty power button, the Macbook shuts down 5 seconds into the 10 required holding the button in order to get the startup options screen.

Is there any way I can repair the permissions? I have a Time Machine backup from a date before when I ran this command if restoring is the only thing that will work. Also worth mentioning is that I have Tinkertool System, Onyx, and CleanMyMac installed just incase I would need a 3rd party tool to fix this.

Cheers,
