I have tried in various ways but I have not found a solution so far.
What I tried:
- SSDT for USBInjectAll
- Patch on clover PTS to ZPTS - 5f505453 > 5a505453 and SSDT for XHC.PMEE=0 in _PTS (DSDT) when Arg0 == 5 (Works as Fix Shutdown)
For now to prevent "auto restart" if a USB 3 device is connected, you must select Fix Shutdown in clover and choose whether to keep the leds always on/off (again)
If anyone knows another solution it would be very useful.
@BoomR If you still have HS 10.13.3 let us know how your build behaves when you turn it off with a connected USB 3 device.
