Comment 90 for bug 774089

I agree with the above posters. This is a _very_ serious bug that kills MacBooks. This needs to be listed in the release notes.

Mine is still dead. It will not boot. I've installed OS X on an external USB drive but bless doesn't seem to work from there.

sudo bless -mount / -firmware MBP53_00AC_03B_LOCKED.scap

I tried making a firmware recovery CD. That hasn't worked for me either.

After I get my MacBook back, I will seriously consider giving up on Linux. This hassle is not worth it.
