Hello! So i've been having this problem for a while now. It doesn't happen everyday but when it happens it so annoying. I'll just be doing whatever on the computer and it just freezes and restarts. I'm not moving the computer or anything. It's the 15 inch retina with 16gb ram and 512gb flashdrive. I have insurance but idk what they can do since it happens so randomly. You can't predict it in any way. I've been thinking it may be a problem with the os? Is there perhaps a crash log on the mac I can find to see how often it has happened? I wanna sell my macbook and buy the iMac. I don't think it would be right to sell my computer to someone when it does that.
