Hello,
Can anyone tell me what KernelAndKextPatches/AppleRTC=true do? The Clover wiki isn't so clear about it... I want to know if it's actually necessary to use it or not? Especially when I already have 'FIX_RTC_20000' in use...

Thanks.

It is a very old patch for AppleRTC.kext. The patch avoids some issue with the assumed length/size of the RTC data which causes corruption of the CMOS checksum. If you don't have CMOS errors/warnings upon booting (from BIOS), then it is probably not a patch you need. It is such an old patch, you'll have to go way back to find detailed information...

I don't think I need it then... I'm probably removing it from my repo too.

Thanks :)

Can this resolve this issue?

VirtualSMC: efend @ no extra rtc memory is present for key erase

$ ./rtcread
AppleRTC I/O failure E00002C2
