black screen after login, Mountain Lion on Macbook Retina

Having the same issue. Guess I shouldn't have thought "Oh wow what an easy upgrade - no issues yet" yesterday...

Enabled graphics switching and autologin and seems to have fixed.

Annoying though.

Having the same issue as well. 😟 I hope Apple is aware of this problem and will be releasing a fix soon.

I called apple support today and it seems that they have no idea on this problem.

They just give me a case number and ask me to go to the apple store to check hardware and sofware conficts.

Please keep us updated!

Thanks

Nicola

thats how first level support works. They dont know anything and send you away. Only if you are persistent and can convince them of a problem they let you through to second or third base 😉

As i stated on the first page of this thread: everyone with the problem should submit a problem and contact support about this. Only if it "hurts" they will notice and not just send users away with a generic message 😉

if you have time to spare you could also contact computer news sites (maybe mac specialized ones) about this issue so they take it up with apple.

Ran this update a couple of days ago and since have not had the black screen after login. Doesnt mean it won't happen again, but so far so good.

Give it a try!

I guess it has more chance to happen after a relative long period of shutting down. How about shutting down tonight nornally and see whether it has the same problem tomorrow morning?

For mine, it always happened in the morning when first turn it on.

NO help.

I installed this patch when still runs Lion.

After that, I upgrade to ML.

BSOD shows up after upgrading to ML.

Hi again folks,

I just opened a case with expresslane (France). I'll keep you informed of the result 😉

We are legion 😀

Thank you very much.

When you contact them next time, metion my case number: 335296057.

I called apple support today and got this case number, however, she asked me to go to apple store genius bar. I am quite busy these days.

Same thing happend to me 😟

I got the BSOD immediately after upgrading my late 2007 MBP to Mountain Lion. Immediately took my laptop to the local genius bar where they diagnosed my problem as a nvidia card failure. Told me I could purchase a new laptop or fix my old MBP for $310. Wrote to Tim Cook. His assistant called me back to inform me that according to their technical staff it was just a coincidence and that there was nothing Apple would do to take care of me because it was out of warranty. I got him to check again only to have another call telling me that it was my responsibility. Looking at these other issues, Apple may be facing a class action lawsuit or at least a lot of lawsuits in small claims court!!!

Hmm, that *****. However, it may just have been coincidence that the card happened to fail at that exact moment, I think it's unlikely that a software upgrade caused the failure. Im sorry to hear it though 😟

I think the Black Screen after login on the Retina is a seperate issue though, it's definately not a card failure as the machine is still outputting, and upon restart is fine. From following this thread, it looks like a software or card switching glitch.

As a note to everyone else, I cannot understand why, but my Retina hasn't done it for about four days now, through multiple restart/shut down cycles. I have GFXCardStatus installed and the Wacom drivers I thought caused the issue, and auto switching is still enabled. Stopped just as quicly as it started. Odd.

To those who have Emailed/got support, do keep us posted 🙂

I guess the new power nap option cause this problem!!!!! 😀

tried ben.lausmans workarround and am blackscreen-less for 2 days now. Will keep you posted if that did the trick for me or if it is just an coincidence.
