I've been using my mid 2012 macbook pro with only 1 problem since I've owned it where in March, my SATA cable failed and needed to be replaced, where I also replaced the drive with a solid state. Now out of nowhere a few days ago, my mac started to go into these restart loops when I opened it from sleep. Maybe 5-10 times it would continuously restart and then once I logged on, it would say the computer restarted because a problem occurred. I took it to the apple store where a genius could not determine the problem and told me to wipe the drive and install a fresh yosemite. Since then the looping has stopped, but it will still restart out of absolutely nowhere, and the error messages have ceased. I have not reinstalled OSX yet, but was wondering if this may be attributed to yosemite's issues with SSD's. It may be a bit early to use El Cap beta, but I've read that El Capital solves an issue with yosemite and TRIM. Anyone else have input?
