Hello pepeipod,

Thank you for using Apple Support Communities! I understand that you are experiencing unexpected restarts with your MacBook Pro. I would be happy to help provide some steps to take next.

Here's a resource that could help:

If your Mac spontaneously restarts or displays a message that it restarted or shut down because of a problem - Apple Support

To help isolate possible causes of the recurring kernel panic, start with the steps in this section:

Isolate hardware or software as the cause of the issue

To try to figure out if the issue is related to software or hardware, use the computer with a fresh installation of OS X on an external drive.

  1. Start the Mac from OS X Recovery.
    If a kernel panic still occurs when started from Recovery, there is likely a hardware issue. See the "Hardware troubleshooting" section below for additional information.
  2. Open Disk Utility and use "Repair Disk" on your Mac's internal hard drive (named Macintosh HD by default).

    Important: If Disk Utility is unable to repair the internal drive, you should back up your important data immediately and if possible, reformat the drive. Consider bringing the Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for further diagnosis. Be sure to ask that, if the drive needs reformatting or replacing, they contact you about escalating your case to a special data recovery service. If you plan to visit an Apple Retail store, you can make a reservation (available in some countries and regions only).
  3. Connect an external drive with at least 10 GB of free space. Note: Make sure the external drive does not cause kernel panics, and is the only device on its USB, FireWire, or Thunderbolt port. Connecting the external drive and its cables to another Mac can help make sure the drive does not cause kernel panics.
  4. Install OS X on the external drive.
  5. Start up from the external drive.
  6. Use Software Update to install all updates until it reports "Your software is up to date."
  7. Don't install additional software on the external drive, but instead use the Apple applications to surf the web, view QuickTime movies, email, print, scan, and/or other activities. Continue using your Mac for the amount of time it would usually take for the issue to occur.
  8. If a panic occurs, select the "Hardware troubleshooting" section below to further diagnose the issue.
    If a panic does not occur, select the "Software troubleshooting" section below article to further diagnose the issue.

Keep us posted with what happens from here.

Cheers!

That panic was detected in kalloc, the dynamic memory allocation routines, probably one of the most heavily tested and self-checked routines in your Mac.


In the fist instance, you have No third-party extensions added, in the second case you have two third-party extensions added.


In each case, the variable was changed from expected by ONE BIT.


This adds weight to the theory that this is a RAM memory problem. However, the retina MacBook Pro models do not have replaceable RAM modules -- the chips are soldered directly to the board.

MacBook Pro 11,1 was 13-in 2013 and 2104 models. Parts may still be available.


If it turned out to be a RAM problem, Apple would swap the mainboard in the field, and send the old board back to the parts depot. There, they might figure out which chip and replace the bad chip with a good one, a surface-mount soldering job that requires special equipment.


A third-party notebook repair might just install a used, tested board, salvaged from a Mac with a different problem, such as a broken display. They may be able to do a repair, but it is not typical.
