Hello — I'm experiencing kernel panics every single time my Mid-2012 MacBook Pro (2.3 GHz, Intel i7) wakes from sleep. Running El Capitan 10.11.3. I look at the reports, but they are entirely greek to me.

Can anyone can tell me what this report means, or if there are any clues here as to what's going on? Here's the latest report:

  • A crash 55 hours after boot might be hard to pin down. Are you looking for general advice? – bmike Jan 26 '16 at 1:21
  • @bmike If his computer is crashing as a result of a kernel panic, I doubt very much he cares about what it is, but rather about making it stop crashing. – William T Froggard Jan 26 '16 at 2:02
  • @WilliamTFroggard I prefer to not assume - you might be right but I didn't want to edit your answer to cover what a panic log means. – bmike Jan 26 '16 at 3:08
  • Just some insight as to what could be happening, if that's possible. I don;t know what any of the above means, or if it contains any clues. I cleared the log files last night and let it sleep, same thing this morning. Here's a link to the latest log, if you or anyone has the time to check it out: dropbox.com/sh/2e707t2bfyyxphp/AADPXGF9TBHVkwiHlR2ZrDoYa?dl=0 – Joe Natoli Jan 26 '16 at 14:07

It's quite hard to tell from that what's causing the crash, but seeing as SoundFlower hasn't been updated since 2014, and certainly hasn't been updated for El Capitan, my money's on SoundFlower being the culprit here. Try uninstalling it, or just moving its kext out of "/Library/Extensions/" and restarting. See if that fixes it.

  • Thanks William. I have a video capture app I use that wants it, unfortunately. Will try your suggestions regardless. Thanks again! – Joe Natoli Jan 26 '16 at 1:29
  • I updated Soundflower last night to a new version that's supposed to be compatible with El Capitan. The software using it isn't running usually, I only use it when I need to create screen capture videos. Could it still be causing an issue even though the software isn't launched? – Joe Natoli Jan 26 '16 at 14:11
  • @JoeNatoli Wow... I've had Soundflower's kext installed for so long, I completely forgot I had it! I haven't needed it in a few years... If the Soundflower kext is causing an issue in your case, it would seem more probable that it is the application utilizing it than the kext. I've certainly never experience a panic from the kext itself. – William T Froggard Jan 26 '16 at 15:55
  • That's what I figured. The app only runs when I'm doing a screencast, which isn't that often — and I never experience a crash/restart when running it. Always after the laptop goes to sleep, even with no applications open or running. Completely stumped. – Joe Natoli Jan 26 '16 at 16:44
  • @JoeNatoli Sometimes, kernel panics can be caused by hardware problems. I'd try restarting into the Apple Hardware Test, by holding down "d" while booting, and run some tests. The extended test takes awhile, but is likely to uncover any hardware problems that may exist. If you have a couple hours, it may be worth running it once. – William T Froggard Jan 26 '16 at 17:47
