I'm not getting this to work properly on the MSI Z77MA-G45. I've applied the patch OK to the latest MSI BIOS, v1.90 and done a binary compare to other versions posted on here and they match exactly. The problem is that after resume from standby the machine is so unresponsive to be unusable and most times the screen doesn't refresh properly. I don't have a single problem with the patched v1.40 BIOS posted quite a while ago for this motherboard.
The only different KEXTs I use from the defaults are LNX2Mac RealtekRTL81 and AppleHDA.
