Kernel panic after installing El Capitan I've upgraded from El Capitan GM to Release today.

After the installer app has moved the install files, the mac tried to reboot but the screen stayed black. I shut it off using the power button and restarted it getting kernel panics every time:

Process 1 exec of /sbin/launchd failed, errno2"@/Library/Caches/com.apple.xbs/Sources/xnu/xnu"


I tried booting in safe mode without any luck.

So I thought that this could have happened because of any faulty kexts. I booted in Recovery mode, used Disk utility to unlock my Macintosh HD, and navigated with the finder to "/Volumes/Macintosh HD/".

The strange thing is that there is no Library or System folder. I can only find these folders under /Volumes/Macintosh HD/Recovered Items/.

So I followed some advices from Apple support forums and deleted the folder /Volumes/Macintosh HD/Recovered Items/Library/Application Support/Virtual Box/". I also moved the kext file from Little Snitch to a newly created folder "Unsupported" to ensure that LS is not the case of the problem.

But nothing helped. Still getting the same kernel panic. What can I do?
Same here, booted into recovery and back to yosemite

cmd-shift-r keys down while booting

I guess 3 of 4 updates have failed for me last few years, getting tired of osx OS updates. Usually installs after a few attempts with startup utilities.

Better make a time machine backup before you try installation.
