Cannot reinstall OS X

dhjdhjdhjdhj · 05-20-2012, 04:03 PM

OK --- somehow an attempt to install some Pro Tools plugins seems to have caused a bunch of bogus kext files to have been installed on /System or /Library and so I cannot reboot my machine.

I tried to use the Recovery system (booted the machine with CMD-S) and selected the recovery drive. After it authenticated me, it appeared to download a new copy of Lion but after it completed and went through a reboot, again my machine would not start up.

On another machine, I burned a DVD with the InstallEDS.dmg file taken from the "Mac OS X Install ESD" dmg and tried to reboot with that. Although the first machine is able to see that DVD, it will still not complete a reboot.

No idea what to do next....any suggestions, free or paid.

Thanks
David

You have to hold cmd-R to boot to the recovery partition. That might part of the problem. Then, once you're booted...

Cmd-S gave me the choice of using the Startup Disk or the Recovery Drive. And selecting the latter does indeed give me the Recovery system per the other link. It was even able to download Lion after validating my apple id etc.

However, after trying/failing with the InstallEDS approach, I tried the Recovery partition again and this time it worked. So I've no idea what the heck was not working.

Thanks for the feedback

I didn't you would get an option. Perhaps your boot drive was hosed enough that the recovery partition was presented to you. Anyway, I'm glad you decided to try again and that it worked.
