OS X Yosemite - Kernel panic

I know this is many months later, been searching support for similar issue, I can not restart in safe mode. that is starting and holding cmd + R, what else can I do? I have install dvd in external drive, how do I boot from the drive? thanks

My panic problem showed up after i installed a SSD and OS 10.10. I finally found that it was the sleep state that killed it. With the SSD, sleep is not a big deal. turned sleep to never and no problems anymore. :-) screen sleep is ok.

btw, my old mac is fast again with the memory and SSD!

i use to have the same problem. after reading the posts and comments here , i have removed (and keep removing every time)this driver , as someone else suggested in this forum " Navigate to ~/Library/Preferences/ByHost/, delete any files that contain "windowserver," and reboot the machine. The procedure may need to be repeated if you regularly connect to an external monitor once it is also connected."

if you don't know how to find it just use finder.

the kp have stopped, i am 5 days now without even 1 restart.

if someone knows how to make an automator command about that ...it would be very much appreciated. pardon my english,not my native language.!

What backups do you have?

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.

so here's what i did:

> made a bootable usb drive with yosemite on it

> pressed fn+alt during startup, selected usb drive and installed it

worked fine on my 2013 rMBP 13".

good luck.

Simply verifying the disk and then restarting got me out of the panic kernel boot cycle of death.

I've been using Mac OS since the pre-Mac OS X era and I can tell you it has definitely gotten worse with time. I miss the Mac OS 9, it was the best operative system ever!

Best of luck!

Hi all,

I have used instructions mentioned by anssi.vaisanen - Remove Avatron Air Display - and it seems that it fixed my problem.
