yes, I installed the Nvidia ´s patcher. So, I have to reinstall the OS(12.1) and then patch again. Is that correct?Did you make changes to the system partition to enable the GT 710? If so you'll need to download the full installer app to update as the APFS seal will be broken, then any modification will need to be made again.
Thanks again @Shaneee for your help...Yes you'll need the full installer which you can get here for 12.1, http://swcdn.apple.com/content/down...ebasc92qkw2iv44e1j9pv09f/InstallAssistant.pkg
Run the pkg and it'll add the App into your Applications folder. Run that and it'll update the system.
ShaneeeFrom an Intel system but it has AMD specific kexts and the kernel patches??? Either way the one I uploaded will work on your system.
