Hi guys, a week ago I installed Monterey on my 2010 MacBook Pro.
It was working fine but I saw that Bigsur would work better, so I did the same thing as the first time when I upgraded with Opencore, but now my Mac is blank when I turn it on. I have tried reinstalling High Sierra from Recovery (formatting the hard drive in the process), and nothing, I have no way to delete the Opencore partition, and when I try to select to boot from hard drive with High Sierra, the screen freezes.
Anyone know what should i do?
