Hi guys, I've tried to install Mountain Lion via both the update utility and the Uni-Beast and no such luck as of yet. When i try the apple update from the app store, it downloads, installs [well it says it installs] and then it reboots back into Lion, its as if i never ran the update. When i try to install via the Uni-Beast it installs and when i go to boot from my main drive, it goes back to the boot-loader selection screen and when i select the drive again i think i can faintly read an error message of 'mach-0 file has a bad magic number' at least thats what i think it says. When i clone my back up drive with lion back everything works fine again. I'm as up-to-date as i can be with regards to software and everything on my Lion install works without fail. Any ideas?
