I haven't seen this particular issue, but I have had a whole bunch of strange, likely firmware-related issues on my Retina. For instance, sometimes the screen just won't shut off when trying to put it to sleep - Closing the lid and the screen/logo stay lit up indefinitely. Chrome and the integrated graphics card really don't play well together - it's caused an OS reboot 10's of times in the past month. Mostly, waking…

"Mostly, waking the computer from sleep takes a fraction of a second but sometimes it takes ~20 seconds to show the screen." I've seen this as well, and it feels related to whether the computer is suspended to RAM (sleep) or suspended to disk (hibernate).

Sounds plausible to me. I suppose it doesn't matter how fast the SSD is... it has to restore (up to) 16GB from disk to memory before it's ready.

Hm, this might explain why my 2011 Air is occasionally on and hot when I pull it out of my laptop bag, too. I only started noticing it after the Mountain Lion upgrade, so I figured it was more likely something to do with their crazy new sleep mode, but hey, perhaps it's a combination of factors?

I don't think the Air can fully turn on in clamshell mode, unlike the pro. This is (I believe) because the air uses its body as a heat sink.

I use my 2011 Air in clamshell all the time.

I keep hearing things like this about the Retina MBPro. Dangit I WANT one, but my spidey sense keeps insisting that this is first round, early adopter technology and that I'll be MUCH happier if I hang onto my early 2008 17" MBPro for another few months or maybe a year until the next laptop line bump from Apple.

Don’t buy. Not as long as they horrific image retention problem isn’t solved and acknowledged by Apple. (It isn’t.)

Why does the laptop power on when the lid is closed? That seems like the design flaw to me. And it could probably be fixed with a software update as well. Still, not very frontpage worthy IMO.

If the laptop gets too hot in a bag, it can cause fire, so it's a potentially life-threatening bug.

I've had my Retina MBP for a month an a half. Only issues I had were graphical glitches in Lion which were fixed when I upgraded to Mountain Lion.

Sure, some apps don't scale their resolution for the screen yet. Photoshop is the biggest problem for me but isn't a deal breaker since I don't spend that much time in PS.

As for the OP's problem, I've never experienced it. Keep in mind he didn't say it was a retina model. I ride a motorcycle with my laptop on my back every day. It gets bounced around and jostled a lot. I've been on 4 flights with it. I've never had it turn on when closed.

I have no idea why anyone would buy a "Retina" MacBook any time in the near future. There are a huge number of popular apps that still don't support it. Lack of Office & VirtualBox support by itself would be a non-starter for me.

Viewing photos, or similar graphics-related work.

No, no it can't. The battery will drain, but not much else. The temperatures you'd see wouldn't even be likely to reduce the lifetimes of components.

This is inconvenient and annoying, but not life threatening. Stop being alarmist.

This is a new setting for the rMBP that hibernates to disk after something ridiculous like two hours. It drove me absolutely batshit, but thankfully you can change it to something more reasonable via a simple pmset command. (I brought mine up to 24 hours before writing to disk)

It is especially bad because the behavior is a frozen cursor while it reads the RAM image off disk. SSD's are fast but on the 16Gb model it still takes 15-20 seconds and feels eternally broken. My old MBP had a progress bar at least, not sure how they messed it up.

In any case, fix it yourself here: http://www.qandasystem.info/apple/disable-stand-by-mode-on-r...

Ah you are right, my bad.
