OS X Yosemite - Kernel panic

Identical issue here. I started Yosemite upgrade, my Mac Pro restarted but now kernel panics repeatedly on boot. Disk and disk permission repairs haven't fixed it. I can't even boot it into safe mode without this same kernel panic! Was running fine until I attempted the upgrade!

panic(cpu 2 caller 0x...): "Process 1 exec of /sbin/launchd failed, errno 2"@...

Debugger called: <panic>

What backups do you have?

I also have this problem but on my 2008 Mac Pro. After installing Yosemite and upon restarting I get an error stating "...restarted due to a problem." And then the mac reboots once or twice showing that same error. And when I try to put my mac to sleep it just restarts and gives me the error again.

The report begins with:

*** Panic Report ***

panic(cpu 2 caller 0xffffff800d01e80a):...

Are you able to boot into Recovery volume, boot with the Command + R keys held down. If you can then select Disk Utility and repair both disk permissions and the disk. Try to reboot normally.

If the normal reboot fails boot again into the Recovery volume and reinstall the system.

It appears my kernel panic upon boot was because of my pc Nvidia GTX650 Video Card (never had this problem in prior versions of OS X with this card). I replaced the card with the old, original ATI card and it seems to be running normally now on startup, restart and sleep. I'm considering attempting to use the Nvidia Yosemite driver just as a test.

Unfortunately my kernel panic is completely unrelated to your MacBook Pro kernel problems but my mac was exhibiting the same behavior which led me here.

Same issue here upgrading a MacBook Air Late 2010 from Mountain Lion to Yosemite.

No USB plugged in. One NAS drive attached plus the Time Capsule.

Kernel Panics and infinite restarts. Had to reboot with Command+R and restore from my Time Capsule which took over 8h.

What's next? Any solutions to the kernel panic?

Thanks

have exactly the same problem updating from maverick to yosemite on a mid 2013 rmbp 13".

i was able to recover mavericks install with cmd r . took 1h. but i need to install yosemite. what can be done about the problem????

Don't have much time to talk, but have you tried doing a time machine of your important Mavericks data, then doing a clean install of Yosemite. Then try the time machine or migration assistant.

Hi! Same error here. I upgraded from mavericks to Yosemite. At first, the system run smoothly. The day after DURING WORK parallels crashed completely. It was not possible to shut parallels down. after this crash, my mouse cursor went crazy. It was too fast to control. Really, never seen this before. Then it tried to restart my MacBook pro (9.1). Nothing happened. Tried it a few times, nothing. So I had to do a cold restart by pushing the on/off button. It started, then I had the same screen like in the post above. After several tries, the restore console opened. But I had to install yosemite again, a repair didn't work out. 1 day later I received a email from parallels advising to install an update. Aha well, done that. Parallels runs but windows had be be repaired. Are you all using parallels? Maybe that's the problem...

Same problem here. I have 2012 mid retina mbp. I get constant kernel panics. I close my lid, couple of minutes later I go to reopen it and there's the error. "your system has restarted because of an error". This didn't happen until I updated to yosemite. I have an appointment with the apple store on Friday. I've tried everything so far (pram, reinstall yosemite, start up in safe mode, and erase HD and do a clean install. Nothing has helped. The problem is still there. Who is in charge of software at apple. Some serious issues going on lately from bricking of iphones, kernel panics look like they are caused by yosemite itself, and apple pay is double charging some customers. Pretty lame... I miss you STEVE!
