I will give an update too, i have installed MacOS, with your efi, and it is working, booting without usb, etc.. And i wil confirm that usb 3.0 works, the only thing there not is working, is the Nvidia gpu! I have been running it the last few weeks, and the only problem i have found, is it cant wake up some times when it goes to sleep... Is it possible you can upload the Power management kext?
