Q: spontaneous double reboot in Yosemite and El Capitan but not before
After upgrading my mid-2010 MacBook Pro to Yosemite, I started having problems where the machine double-rebooted itself (booted, did not come all the way up, then rebooted). It can stay up from 5-30 minutes (most common) up to 12 hours. I've maxed the memory in the machine and put in a new hard drive (though diagnostics checks did not indicate errors with either). Yesterday, I had 12 double-reboots while trying to work. In desperation, I installed El Capitan. Same thing is still happening, only now I don't get the screen about whether or not I want to report to Apple. I'm grabbing the EtreCheck output (I run it after each double-reboot now) but I'm not sure how to tell from that what's causing the problem. I have an appt at the Genius bar this week, but I'm hoping I might somehow get this solved without having to go to the mall during the holiday season.
MacBook Pro, OS X El Capitan (10.11.2)
