All good now cheers!
The USB 3.0 port should work, but not with 3.0 devices, it does work like the rest usb ports for 2.0 only. use kext wizard to rebuild cache and try again after a reboot.Mountain Lion is working now,thank you for your ProBook Installer,I chose F.20 BIOS for my F.27(I think it is the newest) and it also worked. But the Blue USB 3.0 Plug doesn't work, is there any solution for it?
Yup, it still have some problems but I'll be working on it.Is it normal that it worked in 10.7.4 but Not in 10.8? My USB 3.0 hdd worked there without any Problems,I used HP ProBook Installer 4 in 10.8
