I installed MultiBeast onto my MacBook Pro by mistake!

Hi installed MultiBeast onto MacBook Pro by mistake and checked all the boxes to install everything and now when I login to my computer the computer freezes and then starts beeping three times continually. I have to force shut it down by holding down the power button. It only boots in safe mode. Why I installed MultiBeast was because after I installed Mountain Lion it only booted in safe mode. One article said to install MultiBeast and that should fix it. That information was totally wrong. I later found out that it is for PC's that installed Mac on it. Read that apple discussion at this link.

Anyways, I would like to know how to uninstall MultiBeast. I was reading articles on how to but that didn't work. Does anybody know how to?

MacBook Pro, OS X Mountain Lion

- (Hold Command+R on boot)

- Go to Terminal

- Go to your /System/Library/Extensions folder on your main OS X partition (not the recovery one), for me (with my partition called "Macintosh HD") it was /Volumes/Macintosh\ HD/System/Library/Extensions

cd /

cd "/Volumes/Macintosh HD/System/Library/Extensions"

- create a backup folder somewhere and move ALL the kext files out of the "Extensions" folder.

- copy the Kext files from the Lion recovery partition to the OSX disk, e.g.;

cp -R /System/Library/Extensions/* /Volumes/Macintosh\ HD/System/Library/Extensions

- also move the /Extra (in my case /Volumes/Macintosh\ HD/Extra) folder somewhere else

- Reboot while clearing the PRAM; shut down the Mac, start it holding [Option]+[Command]+P+R until you hear a sound and the laptop restarts itself again

in all honestly the only answer might be to wipe your drive and do a clean install of Mountain Lion. If you don't have a data backup from prior to installing Mountain Lion etc then I would be very very careful about what data you put back on. Especially anything from your Library folder.
