[Success] High Sierra on P55M-UD2 - Core i5 - GeForce GT 640

[bbetancur]

I recently upgrade my Hackintosh to High Sierra (macOS 10.13.4 (17E202)) from Yosemite

Almost Everything works perfectly: Web drivers, Cuda Drivers, Ethernet, iMessage, sleep

My guide for this was: https://www.tonymacx86.com/threads/success-customac-original-p55m-ud2-core-i5-750-amd-hd6350.207881/

I just have problems with the USB (Very slow data transfer and horrible sound from the USB interface)

I followed the steps for make the USB works (https://www.tonymacx86.com/threads/...orking-in-ga-p55m-ud2-v1-0-mobo.172843/page-2), but It doesn't work for me coping the DSDT, my system just doesn't start.

Any advice?

Update: I notice that the bios was downgraded to F7 I don't know why. Today upgrade again to F11 and the problem was fixed. My system works perfectly now.

Seems like the default AppleRTC can write garbage to the BIOS. My machine thought I had set a password. I typically disable sleep - I had problems with that even on genuine Apple hardware.

The patch I am using at the moment is here: https://www.tonymacx86.com/threads/high-sierra-on-legacy-p55m-board.264594/#post-1902399 .
