For many months, I have experienced occasional lockups on my Macbook Pro 8,2 running OSX 10.9.2. Actually, I had what I assume was a related problem in 10.8. I have the 2.3GHz Core i7 processor, 8GB of RAM, and a Samsung 840 Pro SSD. I've begun to seriously try to debug this problem, which happens maybe once or twice per week (I'm a heavy user, so this is relatively infrequent), as my AppleCare ends in a few months.

The freezes are sudden and I don't notice they have happened until I try to use the trackpad. All graphics stay the same, but nothing else works. I can't Cmd+Tab. Any video or audio that was playing stop. To reboot, I have to hold down the power button.

I've tried the usual maintenance things:

  • I've cleaned and rebuilt thoroughly with ONYX.
  • I've updated Firefox, Dropbox, and Jottacloud to the latest versions.
  • I've stayed on top of all OSX updates.
  • I ran a full memory test.
  • I ran CINEBENCH benchmarks with no problems.

I'm now looking in the logs for help. Here is what I found today after a freeze:

I assume that the netbiosd warnings relate to me blocking traffic with Little Snitch. I doubt that would cause a freeze (though let me know if I'm wrong). I'm currently suspicious of the CoreAnimation warnings. I've noticed these before preceding crashes, though sometimes they seem to be in the logs even when no crash has occurred. Is it possible that this is causing my problems? If so, what is CoreAnimation and how can I fix it?

Note that I am on my third SSD in this system, and (while I've had warranty replacements) I've always suspected that something about this system is frying them because both have died right after a freeze. Right now I'm ignoring that suspicion and trying to follow the logs in a systematic manner, but if you think these SSD issues may be indicative of something, please let me know.

Update: I just had another crash and found the following information in my console. I wonder what this "previous shutdown cause" part is telling us.

Thanks for your help!

Could you expand the Console log to 20-30 lines some before some after the freeze. –  Buscar웃 Mar 18 at 11:52
    
Did you check this answer: stackoverflow.com/questions/19544207/… –  Buscar웃 Mar 18 at 11:59
    
I see that other answer is related, though I'm not developing my own app and I don't have access to the code. I'm currently wearing the hat of the end user and wondering how I can trace down which of my apps are causing the problem. I'll expand my log snippet. –  Eric Marsh Mar 18 at 13:14
    
I just added some additional log output, though many lines are basically the same so hopefully it is useful. There is a lot more obviously that happened during the boot. –  Eric Marsh Mar 18 at 13:24
    
none shows the fatal error, indicating system freeze? but there is a log kernel[0]: Longterm timer threshold: 1000 ms not sure what it means, lets check. –  Buscar웃 Mar 18 at 13:30
