Found out something quite fascinating about the watch unlock: I tested with two native apple cards. A 2x2 BCM94360CS2 and a 3x3 BCM943602CS for which I added an antenna to the unit and... the 3x3 unit doesn't work reliably for watch unlock. It behaves the same way as my 3x3 Dell DW1560. This is very strange...
It will work for a few minutes after setup and then would fail to reconnect to the watch.

I observed an RTC issue once on the first reboot after I switched from FakeSMC.kext to VirtualSMC.kext (switching from OC0.6.6 EFI r002 to r003). I haven't observed any RTC issues since then. If your RTC issues persist, can you set your rtcfx_exclude=B0-B8 and let me know if that resolves your RTC issue?

In preparation for OC 0.6.7, my config.plist will have the following changes (so far):
  1. Booter > Quirks > ProtectUefiServices: change from 0 to 1
  2. PlatformInfo > Generic > MaxBIOSVersion = 0
I have noticed that OC Sanity Checker recommends different values for ProtectUefiServices (0 or 1) depending on whether the platform is Desktop or Laptop and depending on whether the platform is 8th Gen or 9th Gen Intel. I'm settling on ProtectUefiServices = 1.

Also, my future config.plists will include a Kernel > Add entry for NVMeFix.kext.

Also, if testing with rtcfx_exclude indicates that it needs to be changed to resolve RTC issues, I may change this boot-arg. It appears that we have some flexibility with this, so as long as the rtcfx_exlude range isn't too broad, it will resolve the RTC issue on G3 and G4 without adversely impacting operation of G5 (so all can have the same EFI).
