I installed the latest Catalina 10.15.5 on my m93p Tiny (same configuration as OP).
I used the EFI from the guide. Thank you for the guide and for the configuration files.
Everything works ok, even the sound, except:
1) The wifi because I don't have the supported cards (just purchased the BCM4352 from ebay), so that is not really a problem.
2) Real issue is the system is rebooting after wake.
I already replaced AppleALC, Lilu and WhateverGreen with the latest versions and did not solve the issue.
About 15 seconds after awake it just reboots.
Did anyone have this issue?
I browsed through the postings in this thread but I could not see anything about that.
Sorry if it has been reported and I missed.
