Is there a way to run macOS with Bitlocker?
Depends on what you mean by "run macOS with Bitlocker." Do a web search for macOS Bitlocker. You'll find discussions and solutions.

You're not running with the EFIs recommended in this thread. Have you tried to use the EFIs recommended here?

Use one of the EFIs proposed in this thread and then post your EFI with your requests for help.

@turk101 Also - update your profile so we don't have to hunt for your System/CPU/Graphics. Thank you.

For one, I am not using OC 0.6.5. It's not released for a reason... it's not fully tested and ready.
I have never seen, not even once, this RTC problem from neither of my 600G4 or 800G5 on Catalina or Big Sur... and I mean never.
I am not sure what is different between our installations. I am not using any of the boot args or the kexts either.

everything works great..video...wireless/bluetooth...etc....only problem having is the rtc error on cold boot....am using the suggested fixes...RTCMemoryFixup.kext and Nvram boot args rtcfx_exclude=B0-B4
and have cleared the NVRAM...
Agree with @rafale77 - by using OC 0.6.5 and Acidanthera kexts that haven't even been released yet, you're turning this into an Acidanthera debugging thread. Let's stick with what's released - you'll find that it's hard enough as it is.

There is an RTC issue with 800 G4 Mini. It is very rare. I never observe it during "normal" option and have only seen it during macOS installs and sometimes when running OpenCore tools. Since I never see it during normal operation (shutdown, restart, sleep...) it remains a low priority for me. I am currently running with RtcMemoryFixup.kext and rtcfx_exclude=B0-B4 and am waiting to see if that resolves the rare RTC issues. It seems to me that, whatever the RTC issue on the 800 G4 Mini, it's been resolved with the 800 G5 Mini. I've never tested a 600 G4.
