Update and now kernel panic

Post by brian163 » Wed Jan 04, 2017 10:00 pm

I applied the 3.7.2 update on my mid-2012 Mac Pro running 10.12.2. Upon the required reboot the machine starts to boot, I get the login prompt because I am running FileVault, and then the machine throws a kernel/CPU panic and immediately stops.

What do I do?

I should have mentioned I am seeing the kernel panic error because I am holding down the shift key on boot. If I don't, it just accepts the login, the screen goes blank and after a few moments the machine reboots itself.

Borrowed a computer and started researching further. I'm not versed in decoding kernel dumps but the backtrace is pointing back to a kernel extension installed with other 3rd party software which was also updated recently. So I am pursuing that path at the moment but would still appreciate any guidance or advice. (i.e. does the backtrace accurately point to the offending kernel extension? or could the LS kernel extension be affecting another?)

I experienced similar behavior after updating to 3.7.2 on a 2013 macbook air 10.10.5 (filevault enabled as well). I was stuck in the following loop:

    1. Boot up computer
    2. Enter password
    3. Loading bar during boot
    4. Computer shuts off

Eventually I restored from a time machine backup to get my computer working again.

Same here. After the 3.7.2 update, the computer starts to boot with the logo and progress bar and then a couple of seconds later text scrolls down the screen and the computer restarts with the Kernel Panic message. Then it restarts and does it all over again. This reminds me of the problems I had in November 2014 when Little Snitch hosed my Yosemite install. Obdev swore it was nothing to do with them, until a further release fixed the problem. Looks like I'll have to restore from a Backup and wait for 3.7.3.
