Hi.
As I posted previously above I was able to install Catalina via OC on (almost) the same lap top: [Dell i3593]. I also build it from scratch but mainly used your EFI as my basis. Every thing (almost) works except HDMI (cpu specific issue) and trackpad + sleep (hardware, specific issue I think).
I see that you dropped a new EFI last Jan 21st, can you list which stuff works and which ones don't. Do you any or all of what I listed above as my current issues working?
Thanks in advance.
