GA-H55 USB 3 does indeed work with mountain lion (as done any other 1156 chipset Gigabyte board)
AFTER install but BEFORE 1st reboot, you need to replace the following kexts with the kexts from 10.7.x
IOUSBFamily .kext
IOUSBMassStorageClass.kext
AppleUSBAudio.kext (if you are using an external USB sound card or sound system such as Bose Companion 5)
Search for said downloads; they are certainly available.
Good luck.
Thanks for this info Turnipio. I've installed ML at least 10 times only to get the same results.
No USB control. Let me know if I have this correct.
After I install Multibeast BUT before I reboot and select the ML HD I need to replace those particular kexts (
IOUSBFamily .kext
IOUSBMassStorageClass.kext) with versions from my Lion HD.
Where do these kext reside? In the Extra folder?
I'm using the latest version of UniBeast to build the USB stick.
Choosing legacy for the 1156 chip and 10.8.
I'm also using the latest MultiBeast installer.
I'm not using a DSDT. I do choose some options like trim and SSDT, USB3 and of course audio and LAN.
Is there something that I shouldn't be doing?
One thing I've never really understood about MultiBeast is...
Do I have to repeat options I've already picked when having to reinstall?
i.e. Do I always have to check the audio drivers if they already work?
Does MultiBeast rewrite everything or only the changes you make?
Your answers will help be greatly. I thank you!!
