I use gigabyte x79 ud3 motherboard to install 10.11 GM with big question about USB device. I must need disable all the usb 3.0 in Bios and than allow me to install the mac os. However, after installing. All of the USB 2.0 cannot be used. So, i cannot use my mouse and my keyboard, i cannot log in to 10.11. Could you mind give me some solutions to try ;P Many thanks

Using the instructions from this thread, I made a IOUSBFamily.kext that enables all USB 2.0 ports on my machine. It works for iMac SMBios 12.x - 13.x (14.x should work without any changes).

If you have a way to install it or make another installation using it, I am happy to share. I can modify it to work for your SMBios if you're using something else.

 really thanks for your sharing. Could you mind modify for MacPro 6,1 since my CPU is E5 1620 V2. Many Thanks.

I'm using SMBios iMac 11.2 thanks if you can help. Edit: Sorry I think my USB 2 ports are working though System Profiler shows 8 ports when I have 4 USB2 & 2 USB3 for a total of 6 ports. USB 3 is what's not working at all for me.

I've done the same for MacPro 6,1 and iMac 11,2. I am not a developer, I'm just good at following orders from the thread, so if it doesn't work... sorry. I hope it works.  :)

Hi! I too use X79-UD3 and my SMBIOS is iMAc13,2.

I installed your IOUSBHostFamily.kext but without success.

At my system report I see USB bus like that but with no connections.

I can't use any usb device such as mouse or keyboard.

Seems I need DSDT... right now I do not use any. My /CLOVER/ACPI/patched is empty...

Could you please send me yours?
