Hello Everyone!



I am trying to install Mountain Lion on my desktop with the following configurations:



Motherboard: GA-Z68-MA-D2H-B3


Processor: Core i5 3570k


GPU: Intel HD 4000 integrated Graphics


Hardisk: WD 750GB


Partition Table : GUID


Partition 1: EFI/System


Partition 2: 65 GB Windows 7


Partition 3: Data Disk


Partition 4: 65 GB Lion 10.7.4


Partition 5: 65 GB Mountain Lion GM


Bootloader: Chameleon 2.1 svn r2030(using 1 gb flash for booting and Extras, Internal hdd has on windows boot loader)



My problem is that Lion boots and installs fine, but when i use a Mountain Lion USB install disk after all the kexts get loaded i get to install screen but my keyboard completely stops working and mouse can move around but clicks are not registered for around 5 min.



I installed succesfully, but still the same problem booting in. No keyboard or mouse for awhile, although its not the os itself cuz all my Open At Login apps start up and work normally..



Anyone have any idea what i can do to speed things up.

Including your system info is great, but would have been best to include what kind of mouse/keyboard connection (USB, Bluetooth, PS/2-or combination of the three) :) If it's USB, just try adding USBBusFix=Yes to your boot.plist or if still problem try changing the bios USB settings for EHCI handoff and/or legacy. If bluetooth, gonna need more info on it. If it's PS/2, really time to upgrade.

If all else fails try using Lion version of IOUSBFamily.kext and IOUSBMassStorageClass.kext. Not sure if second one is needed barring a dependency issue.

I've been looking everywhere and still haven't found a solution. For a bit there I thought it was only me experiencing those same issues. But I'd love to find out how I can get this fixed, it's a real annoying bug. :hammer: My system is down below in the sig, and i'm using USB everything.

Looks like you don't have that option. Besides using USBBusFix=Yes make sure you use these ports pictured

and try toggling the different option pointed out, may need to try a few different ones.

Dear Community,

I've the same problem.

Board: GA-Z68AP-D3 Rev. 2.0 Bios FD
CPU: intel i5 3570k

Bootloader: Chameleon 2.1 svn r2030


I can move the mouse but can't do something. After some minutes it works. In Lion I had the same problem and changed the kernel. Then it worked.


But there are only some kernels for 10.8 and all I could find didn't work.

Can anyone help me?

The solution: Boot with kernel-flag "-f". Maybe you have to delete AppleHPET.kext in System/Library/Extensions.
