Mac stuck at the loading bar, when trying to boot from macOS Catalina Patcher I want to install Catalina on a MacBook Pro (13-inch, Early 2011) with 10.13.6 (High Sierra) installed. Therefore I made a bootable USB drive with the macOS Catalina Patcher. First, I had the problem that the USB drive wasn't recognized. Now I used another USB drive and now it will let me boot from. But it always is stuck at the loading screen (nearly 100%). What I'm doing wrong?
I tried safe mode (with shift), reset the NVRAM/PRAM (with opt+cmd+P+R) and I don't see a value in reinstalling MacOs in my case.
What can I do to successfully boot from the USB drive?
Now I deleted the patcher and everything related to it from the machine. Then re-download the tool and also created the bootable USB drive again. I was able to boot from the drive and also install Catalina. But the MacBook again hang at nearly 100%. Then I restarted the machine and the setup dialog appeared! Yes, my MacBookPro8,1 is supported!
As an alternative I'd have tried another patcher.
