After recent Mavericks upgrade, my MacBook Air 2013 has issues - mainly restarting because of a problem. I thought parallels was the culprit (battery drain) - and it is a battery drain, but lately it's been restarting even without Parallels running. Just a minute ago, I put it in sleep mode, disconnected the display & power, headed home and opened my screen (literally 5 mins later) - to the restart due to problem screen. Battery is at 100%. I'm at a loss - any help would be greatly appreciated. I'm inserting the auto-generated report I sent to Apple upon the restart. I don't know how to interpret. Thoughts?

Apple Support

Apple Support recommended I uncheck the "Put hard disks to sleep when possible' - both under battery & power adapter profiles.

Then wait for an update that addresses the issue.

Hopefully it helps.

Interesting, perhaps Apple knows something and others are having the same issue. I would think though that putting the hard disks to sleep shouldn't have any bearing on much, since that doesn't really do much for an SSD drive (which has no moving parts, so nothing to spin up or put to sleep).

I will say though, I was getting the same types of kernel panics, referencing the GPU and IOkit like yours is doing, on my mid-2010 MacBook Pro when the graphics card was getting ready to go on it. It ended up being a known issue and the only fix was to replace the logic board. So if this continues, you may have to press for that.

Electrical malfunction

what you're discussing is the beginning of the boot cycle malfunctioning the Darwin kernel is the first teach outside of the directory services command wine DSC L architecture which UNIX the open-source platform in which Apple launches their operating system software beginning with their daemons (like efi PC) then kernels, leading the 39 languages that make up "Darwin" what's currently the moniker for the 36,000 contributors and close to 40 languages that are recognized today for the open-source software and platform of directory services commandline contributing together to make up the second platforms currently recognized for the nine operating systems of OS X . Apple own a hard drive configuration or command line at the time that they launched so they utilized a platform unix for their hierarchy of filing systems similar to Linux. If you know anything about binary coding the ones and zeros the total electricity to take a left or right on the chunk of metal and gold prongs of your hardware- and the most essential programming that exists inside of computer, it is indicative that it is healthy when a boot chime occurs at launch. Every computer and every platform running all operating systems make this indication, called a POST (power on self test) a quick electrical test ensuring all components are capable of doing their job. If a full circuit isn't run through the mag safe assembly across the logic forward through the battery and back to the mag safe port, electrical failure occurs. Try resetting your SMC and PRAM. A very simple procedure by holding the keys when unit boots, and overhauls electric system. At worst computer may need new battery removing bottom plate and pulling battery clip from computer plug-in unit in and trying without battery will ensure that this is indeed indicative of necessity for battery replacement. These units were also plagued with faulty EDP cables where the LCD attaches to the logic board the first hit in the logic towards essential electrical circuitry causing faulty display assemblies appearing have backlight issues in the ability to produce electrical circuitry- being the LCD accounts for over 67% of battery used laptop. I've seen inconsistent electrical issues and the 2010 two 2013 MacBook airs several times all LCD EDP cable replacements in repairing this issue also record in the technician service guide available to certified professionals (I hold all of apples pro certs).
