Original Question: "MacOS Catalina to BigSur"
Hi,
My gf has a macOS Build where she updated from Catalina to BigSur without checking whether it work first. Currently the computer boots and shows the apple logo and then reboots.
To be honest, I didn't build it and understand very little about hackingtoshes. I was looking for a way to troubleshoot the issue without having to re-install.
Any ideas where to start?
