Hi, I have found a problem with PS2 mouse on the latest version of chameleon (I think).
I'm afraid I'm no expert and have always found that for me the Chimera 1.11.1 installer works for me.
However I now use Chameleon wizard for a few tweaks and the other day it offered to update the boot loader.
I did that and then lost PS2 mouse, so I loaded PS2 mouse kext and all was well. Or it was until I did a restart from Win8 into Mountain Lion and then lost PS2 mouse, did a restart and it came back.
At the moment I have deleted PS2 mouse kext and reinstalled Chimera 1.11.1 and all is well.
Just thought I'd mention my problem.
I'm sorry I don't know what version it updated to as I just accepted the recommendation from Chameleon wizard.
Mike
