Hello Guys, i have a MacBook PRO early 2010, i have 2 disks, maverick installed on the 128 gb SSD, and the other stuff on the HDD (movies, music, etc).

The problem is that everytime i m starting my mac it's restarting once, sometimes two times, without reason. I have the latest Maverick version.I also copied the error debug info. Can you guys have a look please ? Thanks.

Did you try to ZAP your PRAM?

Did you try to reset the SMU?

Did you check to make sure your RAM is seated properly?

Try those things.

Did you try booting from both disks?

Did you try re-installing OSX?
