Failing that and assuming you have NVRAM working, try the sudo nvram command that defines a null wake-failure parameter. That certainly fixed the CMOS reset issue I had from Catalina 10.15.4 and that still happened in Big Sur. I have already tried Most of the options with rtcfx_exclude=00-FF and RTCMemoryFixup.kext with No Success... I still have the F1 Reset any order Help will be appreciated Quote Link to comment Share on other sites More sharing options...
