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

I uninstalled little snitch, but the error still existed.
I have just found the following instructions which helped:
“Those with Little Snitch installed may have no internet access. You won't even be able to reach your router or ping out, despite being correctly connected to wifi. While Content Filters will automatically disable itself with the incompatible macOS version, you need to disable DNS Proxy filtering.
System Settings > Network > VPN & Filters
Set the Little Snitch DNS Proxy filter to Disabled and internet access will return.”
You will need Little Snitch version 6.3.1..
Do you have Little Snitch installed? Heard a report yesterday of it interfering with upgrading to Tahoe.

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.

Here’s the error that causes it to freeze, just came back after I tried Safe Mode
