OS X Yosemite - Kernel panic

Since upgrading to Yosemite I have had 4 kernel panic crashes and bluetooth and wifi issues. Seriously buggy OS, I moved away from windows 10 years ago as it was too buggy now Apple has become as slack as microsoft!!!!

I also have a similar problem and I am using a 2012 iMac. Yosemite has been running for several days without any problems. Then i came to my desk to see that it had rebooted on it's own and when I restarted I got the warning dialog saying the system had not closed normally. This has now happened again. I am convinced, after reading all of the reports on the Net, that there is a bug in Yosemite causing this. I have made no changes at all to my system since upgrading from Mavericks. I am sure Apple is aware of this by now and hope they are working on a upgrade that we will see very soon. Apple? Yes?

"I am sure Apple is aware of this by now and hope they are working on a upgrade that we will see very soon."

Would not pin my hopes on Apple sorting this out quickly. Look how they allowed the issue of ejecting external hard drives to run and run. Apple's cabal like behaviour of not even engaging on these forums can be frustrating.

Ok, seems that my problem is solved (for now). I erased my hard drive, erased all partitions, created a new one and installed OS X Yosemite using a bootable flash drive. then, I recovered my system with Time Machine.

Wow, sounds like several of you are having way more serious problems than I have - so far at least. Currently it's just a minor PITA, but since I'm running on a SSD RE-boots only take a few seconds. No data loss that I'm aware of but I did have to do a disk repair for some directory corruption. If all else fails I've still got Mavericks sitting in a disk caddy in place of the SuperDrive.

By the way, be sure you send those crash reports to Apple. If they're looking at anything, that's what they're looking at (ie there's automation collating the reports) I seriously doubt they're paying employees to sift through zillions forum posts.

Three weeks on and still no dice. Have tried over a dozen times to install Yosemite on this new stock 15" rMBP and every time I get the prohibitory sign. Doesn't matter if I've wiped the SSD and installed from USB, wiped the disk and installed from Internet recovery, or downloaded form App Store on a clean recovery of Mavericks (not a Time Machine restore). It's the same every time, install routine starts, reboots after 10-15 seconds and I immediately get the scrolling code of a kernel panic, followed by the machine-stopped error message. Manually powering down and powering back up yields the circle/line - every time. Genius Bar is still telling me not to upgrade to Yosemite because of known issues and because they themselves were able to replicate this issue.

This is getting ridiculous...

Funny all these issues were not picked up earlier considering this the first OS X that Apple released in beta form to even ordinary mac users who cared to volunteer. You'd think the official release would be perfect.

UPDATE: After numerous attempts to fix problems with my system - some identical to this thread, some different - and replacing most of the insides of my computer, Apple decided to just give me a new computer. I installed Yosemite and migrated my info from another hard drive. It has only been 1 day, but so far everything is running fine. This forum makes it difficult to narrow down. There are both older and new computers running different setups. There is no common denominator from what I can tell. Right now, no more Safari problems, Mail problems, Kernel Panics, self-rebooting, etc. I hope I am not jinxing it, but just wanted to give an update.

I found a solution that worked. I have a late-2013 mac book pro. I tried to upgrade to Yosemite multiple times after uninstalling different apps all the time getting the kernel panic.

I did exactly the following and it worked.

1. I backed up everything

2. I installed Yosemite

3. Kernel panic

4. Started recovery mode

5. shutdown

6. powered up and immediately pressed option-command-p-r simultaneously

6a. this resets something called parameter random-access memory

7. hold these keys until I heard 3 ding sounds (apple says you should hear two, I got three)

8. Yosemite started installing

9. All systems are working.

Please share this to help others. Hope it works for you too!

After upgrading to Yosemite from Maverick on MacBook Pro (new one with 1TB SSD / 16GB memory I had the crashing. I also did upgrade on mac air, mac minis (2 different ones of very different versions.) All of these crash.

What I learned.

1) Upgrading the drobo driver helped a lot.

2) Running the parallels 8 upgrade helped a lot. Suspect Parallels to be major issue but I am not curent.

Safari seems to have an issue. Much of this was couple plug ins. I disables those.

So on all my computers I went from crashing every 30 minutes to once every 2 days or so.

I also configured the iPhone to use the FaceTime app ( I guess ?) where the phone rings onto my mac.

This seems to have issue that when my machines (any of them) crash, I get no vm notification, text, email on my iPhone until I reboot phone.

So I am novice on apple but have doe computer stuff for years on mac / linux. I would appreciate if anyone has instructions on crash dump.

I run quite a few applications on my computer. On one computer I did not install very much except the parallels and drobo driver. They are acting roughly the same so my guess is that the backup drivers, mac phone interface stuff for FaceTime, safari, and parallels are where most of the issues lie.

Any more suggestions on crash file understanding or other troubleshooting is of value to me if anyone can help

So I just had the **** thing reboot when I clicked a link in chrome. No kernel panics yet but I did forget something. I uninstalled Juniper Junos Pulse first. My drobo software is up to date and I do have PGP. I'll keep posting if I figure anything else out.

I have a brand new Mid-2104 MBP - had it a week or so. Yesterday it just rebooted on its own for no reason. It also seems to have problems displayed graphics on certain sites...mainly sites with streaming video. It briefly looks like a Windows system crash or virus from the 90s...like you see in them movies. Don't know if it's a graphics card issue or RAM issue or what. It's a week freakin' old.

Bovine75, I suspect your problem is that you have bought way ahead of time (Mid-2104 MBP). My crystal ball suggests that by that year Apple would have long gone the way of ..., I was going to say Microsoft or simply a bad product/service but that seems infinitely optimistic. Anyway, welcome to the Hotel Apple, such a lovely place..."...all just prisoners here, of our own device"
