Hi there, I’m hoping that someone can help please.
I’ve got a 2011 17” MBP. I’ve disabled the faulty AMD Chip so everything should be ready and straight forward to upgrade to Catalina ( using dosdudes patcher program ) however I’m hitting problems like :
macOS could not be installed on your computer
An error has occurred while updating firmware. Quit the installer to restart your computer and try again.
I decided to go a different route and also got this message :
This copy of the stall macOS Catalina application is damaged, and can’t be used to install macOS.
I’m downloading Catalina onto USB and going that route.
I’m current running Hi Sierra .......
Can anyone offer any suggestions to help me please ?
Many thanks in advance
