Hi, I have a pretty stable setup finally, using on board wifi, ethernet, no addon cards. Hoping to test TB later, for now no devices, but I have it enabled and appearing in mac Info under Thunderbolt. I know TB relates to USB, and can be problematic, but I am pretty sure my issue is not USB related or TB. Not sure about BT.

I had a couple unexpected crashes when waking from sleep.

One happened yesterday at 17:25

I see in Diagnostics Report

"Sleep Wake failure in EFI"

It contains

Sleep Wake failure in EFI

There is nothing under Crash Reports for this date. Here https://www.hackintosh-forum.de/forum/thread/53915-problem-mit-ruhezustand/ there is talk (in German) about RTCFixup kext maybe being needed, but I understand it involves very time consuming procedure to try and find the trouble memory regions. Even though nothing outright says it is related. Or?

SYMBIOS is 1,1. Settings fairly typical in my config. But maybe something to look out for?

ideas?

thanks
