tunecino commented 5 years ago

First of all thank you for this great patch that made my computer usable.

All cases seems to be covered now, so no more random restarts, except for one case, is when coming back from a sleep with the following error report:

Panic Report panic(cpu 3 caller 0xffffff7f88795705): "GPU Panic: mux-regs 3 3 7f 0 0 0 severity 3 switch-state 0 IG FBs 0 EG FBs 1:0 power-state 0 3D idle HDA idle : \n"@/Library/Caches/com.apple.xbs/Sources/AppleGraphicsControl/AppleGraphicsControl-3.14.49/src/AppleMuxControl/kext/GPUPanic.cpp:149

The Patch worked fine and SIP is disabled:

As noted in that output, it is a macOS 10.12.

Not sure how macOs is structured, I see the reported panic related to a file under /Library/Caches. Does that mean the OS is using older version of files before being patched? Is there a way to remove cached files? If yes, would that fix it? Thank you for any suggestion.

Hi ! Your issue has been reported in #32, unfortunately I don't know how to fix this. My only recommandation would be to power the MacBook off instead of putting it into sleep mode.
