My MacBook Pro (2019) keeps restarting after updating to macOS 26

I am in a loop with my MacBook Pro after upgrading to MacOS 26. It starts up normally, then once the finder loads the Internet Connection is never made, and then I see an error message "remoted experienced a problem" once that message shows up, my mac goes into overheat and then Restarts.

and this is after you log into your account?


To trouble shoot further you can:


—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test. Caches get rebuilt automatically.


This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.

 


—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 




unplug all non-essential peripherals when testing

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS

Yes it’s after I log in. I did try Safe Mode and not sure if I have it correct for MacOS 26.. because it doesn’t seem to recognize the shift key. But it did boot back up normally after I ran disk repair with only some graphics errors in the finder. I have a startup Sequoia ready but I can’t select that as a startup disk for some reason.
