Computer Refuses To Start
My MacBook Pro won't start up. Every time I try to start it, it comes up with this message: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again."
Behind that is this error message (May not be 100% accurate--just a few characters were covered by the restart message)
panic(cpu 0 caller 0xffffff800053e12f): "Process 1 exec of /sbin/launchd failed, errno 8"@/SourceCache/xnu/xnu-1699.24.8/bsd/kern/kern_exec.c:3546
