Trying to upgrade from Catalina, it sticks on "finding upgrade"
I've tried upgrading to Ventura, then even Big Sur from Catalina. It won't move past the finding upgrade screen. I've tried restarting in SAFE MODE but it stalls at the end of the progress bar ( for 5 minutes and then I gave up and restarted normally, which was fine.)
Not sure what's wrong. Tried turning off anti virus software - still no change.
Help?
