I have a new iMac 27" that keeps shutting down when I put it to sleep, & sometimes if it is just left for several hours it'll do it, even though I have it set not to sleep. It then needs to be unplugged for a few seconds, then after about 15-30 seconds it restarts. I just got it in October, it's running Yosemite. It's the 3rd iMac I got from Apple, the first 2, refurbs, did the same thing & I figured I'd gotten 2 lemons that didn't get repaired. Now the 3rd one they sent, a brand new one, does the same thing. Has anyone else had this problem, any ideas what may make the machine shutdown & not respond to the on/off switch?
