Since I updated to Yosemite my mid-2012 MBP crashes when I open the lid after a long sleep. I have read numerous posts about other users experiencing the same issue, but all of their solutions have failed for me. I am attaching the error report information in hopes that someone might be able to shine some light on the issue(s). I have upgraded the HD to a samsung evo SSD and the memory, but never experienced any issues like this before Yosemite. I am getting extremely frustrated as it is difficult to resume work after shutting down from work to home and losing anything I have open. What can I do to fix this issue? What has worked for people with the same issue?

UPDATE: Recently upgraded to new Corsair Vengeance memory, and everything seems right as rain. Thanks @mtoro!

  • I have the exact same issue here (MBP Mid-2012, Crucial 16GB RAM, Samsung SSD 1TB). I don't know precisely what could be causing the problem since I upgraded to Yosemite, 16GB RAM and 1TB SSD at the same time. Although the hardware test did not show any issue with the new 16GB RAM (or new disk), the problem went away when I exchanged the RAM with the original from Apple (2x2GB). Currently, I am buying a new 16GB RAM from Corsair to check whether it makes any difference. If I get sth I will posted here. – mtoro Feb 1 '15 at 23:17
  • That would be great to hear your findings, I am kind of at a loss as to what to try next to repair the issue. – TNCodeMonkey Feb 2 '15 at 14:03
  • Seems like its affecting all MBP mid 2012?? Mine is mid 2012, all original parts, no replacements. Its connected to a Thunderbolt display and crashes many times after long sleeps. Called Apple support and they told me to do a full Yosemite reinstall. Did that and still have the problem. – user117301 Mar 7 '15 at 21:16
  • I replaced my ram sticks and everything works great now. – TNCodeMonkey Mar 13 '15 at 23:38

So here is my report: I have bought a 16GB 1600 MHz DDR3 Corsair RAM memory to replace for the former Crucial (16GB) I had. After installation, I ran the hardware test and no issues showed up. I've been working in my MBP for 2 days now with no problems at all. Basically, when I open the lid every morning it works just as it should be, fast and efficient, no kernel panics, no booting issues.

My kernel_task went from about 450MB to 950MB though (same issue with the former Crucial 16GB memory). However, it seems to be normal when upgrading RAM and it is not a big deal since I got other 15 GB for further tasks. In other extreme cases, some people had up to 4GB of kernel task (not my case). Here there is a link about that specific issue if you wanna have a look: http://forums.macrumors.com/showthread.php?t=1395156

To sum this up, in my case changing the 16GB RAM from another producer made the difference. Hope this helps.

Good luck!
