Hi there,
Thanks for all the help everyone (and thanks @roguedesigner).
The issue is now resolved, there was some late night "fun" I would have liked to have avoided
The solution, for anyone else who might have this issue;
- You don't need to reinstall OS X Lion (10.7.x) I think, I did in the end but that did not even work (still crashed at boot), it was a waste of time and in fact it made things slightly worse as I had to run a lot of updates in the end. After the install however I did;
- Boot in Recovery Mode (Hold Command+R on boot, this is only available in Lion AFAIK)
- Go to Disk Utility
- Mount your existing mac partition (the one with the real OS on it that won't start) if its not already (mine wasn't because I am using disk encryption, so in Disk Utility I have to "unlock" the drive first, typing in my password)
- Exit Disk Utility
- 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
- 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.;
Code:
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
- You are now in OS X started again!
- Re-Install the latest OSX Patch (in my case 10.7.2 -
http://support.apple.com/kb/DL1459)
- Reboot
- Install any other updates (Apple Menu -> Software Update)
- DONE!!
And so this is for if you accidentally install Multi Beast 4.1 (Multibeast 4.1 or 4.10?) and because there is now way (how to / how-to) uninstall Multi Beast. Also, Safe Mode does not work, it just hangs there.. so do the steps as I said. Shame there is no how to uninstall multibeast
Thanks again..
Cheers,
Daniel
PS: If you just try to remove certain Kexts sound will likely not work. You have to remove ALL of the ones and copy over the bare install ones as is described above..
