<< Solved >> Computer Won't Shutdown and freezes when waking from sleep

[cojaxx8]

Hello,
Been running a Hackintosh for a good month or so now with good success. One of the outstanding issues is that when the computer shuts down it turns back on, and if it goes to sleep it will wake up OK but then freeze for 20 seconds or so afterwards.

Things I have tried so far:
- Implemented Framebuffer patching
- Implemented custom SSDT patching for USB
- Implemented native CPU/IGPU power management fix

From what I've read both custom SSDT and CPU/IGPU may have interfered with shutdown but after implementing those the issue remains.

Attached is a diagnostic file. Is anyone able to lend a hand or point me in a right direction?

Regards,
Peter

I think it may be fixed now! After doing a bit more searching I put installed, EmuVariableUefi-64.efi, in drivers64UEFI folder and shutdown/sleep works!

I'm not entirely sure what this file (driver?) does but seems to do the trick.

Will monitor over the next few days and report back any issues.
