New 2013 Macbook Pro Retina won't restart or shut down

Barring an incredible coincidence, the most likely explanation is that you have installed some software with system-level components that aren't really ready for Mavericks. Have you installed any such software?

Another explanation would be having run a system "cleanup" or "optimization" utility that doesn't know Mavericks well enough to avoid damaging it, but that seems less likely given that you've had the computers for a few weeks, not long enough to need "cleanup" or "optimization."

Mine is the same. Wont shut down needing hard shut down. Display won't wake from sleep while in user login screen without logging in blind. Constant wake, sleep and shut down issues since purchase. Updates are not addressing the issue.

I'm seriously considering returning this machine - it's just not good enough. I am not running any system management software. I've tried force quitting all apps, but it still wont shut down. No error messages, no timeouts, just wont turn off without pressing and holding power button.

I have the same problem. I am fearful that all these hard shutoffs will damage some system files. I called support and the tech said he hadn't heard of this problem before. I was the first. He had me do a lot of startups holding many different combination of keys because the system was stuck on the apple logo but the display was distorted with pink and grey pixels. finally one of the things that he had me do which downloaded some system startup files fixed the issue for about a week. Now i am back to the same situation. On Mountain Lion i did not have these problems. My other mackbook pro non-retina does not have this problem.

Mine seems to have stopped not shutting down. Not sure what's changed.

Still have to login blind if machine has gone to sleep while on the login screen. Macbook is used by whole family, all with our own accounts so this happens frequently

took mine into the apple store. They say it appears to be the video card. Luckily i called into support 3 days before warranty expired. They are replacing the logic board and will be ready in 4 days.

Dear all, I've a same problem on my macbook pro Retina, bought in February 2012 and upgraded with Maverick in last December. My mac shutdown after few minutes. and when you come back and click on pad or any letter on keyboard, it's no answer! need to restart forcing and several time I've my screen dark but after PRAM cleanup and restart, the screen lightuop and works correct...

I've had a mac diagnosis with Mac support and everything are fine and correctly welldone. But this kind of Bug seems like the video card concerns and need to change by replacing a complete logic bard. I'm really surprised that no possibility on this Mac, to change just the video card neither the memory card if you have memory problem!!!

After one year and a half my Mac is now out of warranty care and I need to change all logic Board component!! cost around 500 $ even I've bougth my Mac around 3000€. It's not fair from Mac service.

But I just discovered this article (see the link below) and will try to do that. Maybe this can fix this bug.

please have a look on that maybe Chrom is the origine of this bug.

Second solution to avoid automatic shutdown and restart forcing again and again, just make your Mac sleep voluntary by click in the Apple menu. This option works well.every time when you come back and insert your password Mac wakeup and works perfectly.

Has anyone found a solution to this? For apple to say that this is a software problem and that all i can do is restore my computer to factory default is complete crap. For a machine that cost close to $3000 I'm a complete loss here....
