Hi, thanks for your guide, I haven't exactly followed all steps, but some parts were very useful.

It seems these usb3 drivers are working : http://www.osx86.net...ll_drivers.html, couldn't actually try the usb speed, I dont have an usb3 device, but the controller is recognized by the system and does work, also the sleep function seems to be still available.
No luck with the PATA so far tough : /

Just FMI, did you patch the DSDT yourself, and if it's the case, do you remember which patch you used ?
Also is there any particular reason to use the MacPro(5.1) model ? I know the chosen model affects the loading of some kexts but I did not find any precise insight on this point.

So far I've used the latest Imac (12,2 I think ?), it seems to work anyway and I dont have to remove "AppleTyMCEDriver.kext".

(Just FYI I'm new to this, so I'm probably doing some mistakes )
