Hello everyone who reads my problem,
So, I've managed to successfully install Catalina on my latitude 7280 using the OpenCore website however my trackpad is not working and I've tried several kexts but with no luck.
I'd be very thankful if someone help me fixing my trackpad issue.
About that the clover icon that shows in my config file, it's because a friend of mine tried to fix my trackpad issue and maybe he did use clover for some reason, he later figured that clover is not supported by OpenCore
