black screen after login, Mountain Lion on Macbook Retina

I doubt that they were installed. I updated through Software Update (Apple Store) not downloading the patch. It just showed up after the updates search.

Yes, Power Nap is there now too. In yours too?

The bad thing is that now I am worried about seeing the black screen again later on... 😟

R.

Provided that I'm sure to already have applied SMC update for PowerNAP enable and provided that the PowerNAP function was NOT enabled before this patch... if you have PowerNAP (I have too), I'm really confident that you already have patched your rMBP via the AppStore updates releases some days ago 😉

You are then really wrong, sorry. The patch appears in the logs as applied:

MacBook Pro Retina SMC Update:

Version: 1.0

Source: Apple

Install Date: 8/1/12 8:28 PM

CET time.

No earlier versions.

I am not saying that this is the solution as it seriously looks it is not for several reasons. I am only saying that I have had not the black screen problem after I applied it.

And I am worried I may have it again :-/

R.

As expected the problem is NOT solved with the patch. Trying several restarts with differents apps running brought back the black screen.

Sorry if I mislead anybody.

R.

Trying several restarts with different apps?

Does this involves changing the resolution or have a display on the machine?

If not, I'm interested what you just did to get the black screen again. The only way I get it is when my resolution changes and the dedicated GPU switch to the integrated or vica verca.

VBox at fullscreen.

Hi All,

Its been several days and multiple reboots and ever since I toggled auto login, there has been no occurance of the black screen. Anyone with similar experience?

The key ingredients for making the black screen soup is:

1 x Auto login = Off

1 x Display resolution changed to "Scaled", and choose anything but "Best (Retina)" option.

That odd to help.

After some experiment I have to say that the external monitor or changing resolution is not the problem.

I've installed mountain lion again (clean install) So format the drive, install from the installer in the appstore en got a fresh mountain lion install in 20 minutes.

Then I didn't changed any option or plug other hardware on it and restarted the system. After filling my password at the login --> black screen 😟 . After 2 attempts, the 3 time I got my desktop.

Again erased the HD but installing a copy of lion. Same procedure. I've restarted it 10 times, waited, put in a external monitor and etc. Never got a black screen.

So I would think it's a mountain lion bug, but why are there only a few people who having this problem??? If it's not caused by a third party application or something.

No clue here....

I have been reading these posts for a week now hoping someone solved it. I have a brand new machine and upgraded to mountain lion. Same issue. I read about the graphic switching changes, but wouldn't that impact battery life? Its a shame they havent fixed it and some people have to disable features of a brand new laptop.

What i would like to know is if anyone thinks the keyboard could be at fault. I found that if i login, and dont hit the enter key, but rather use the mouse to click the little arrow, i never get a black screen. Odd huh? Why that would have anything to do with this issue is beyond me. Maybe it doesnt but i dont get black screens when i use the mouse.

So even at the risk of sounding insane, for the sake of other, i posted this for them to try.

i only get this issue on a fresh boot, so for me only putting the macbook to sleep and not shutting it dowm seems to be a workarround for now.

Dont mind it much is i like the powernap/always on functionality like iphone/ipad has it.

Well unfortunately, I have to report my, clicking vs. keyboard concept is not true. Right after i posted this, the next boot, it blackscreened again, and i was clicking to login.

Noted: it blackscreened the next reboot after i was showing off the resolution of the retina display with SwitchResX. I am going to see if stopping that daemon before rebooting has any impact on resolving the issue.

This is exactly what I'm experiencing, sebastion. The issue never occurs on login after wake. Since I normally simply close the lid after a session and open it back up later and get back to work, I haven't seen the issue since I installed ML and the subsequent patch. I have logged in after wake *a lot* since installing ML.

When I do reboot the machine (which I only did to see if I still had the issue) it always follows the same pattern, two boots to black screen, then on the third boot, just after login, the machine displays a dialog that explains that the machine crashed and asks if I want to re-open applications or not. Doesn't seem to matter what I answer, the desktop finally appears.

Always three reboots. Anyone else have that pattern?

I have exported the logs over three boots from the console application and have briefly looked over them. There are certainly some suspicious exceptions related to the window system, but I'm pretty new to OSX, so I likely won't be able to nail it down.

What I have in common with others is:

* autologin turned off (haven't tried to turn it on!)

* running at 1680x1050 (reported this incorrectly in my previous post)

* PowerNap on while plugged in only

* auto graphics switching turned on

I do not have any 3rd party tools that adjust resolution or report status on the graphics hardware. I have not attempted to connect a second monitor. Just as a side note, I also do not have Chrome or the Android dev kit installed (I have read of unrelated issues with some Google products and the Lion kernel lately). Or Firefox for that matter. I have Xcode/Unity3d/Blender installed, but other than that, the system is pretty close to stock. I'm fairly certain none of these program are related to the login issue.

Exact same scenario 😉

I can add that the only way I got to recover my working screen after a "black login" is to SSH to my rMBP, then remove the "com.apple.CoreGraphics.plist" from the "/User/<myuser>/Library/Preferences" directory and make a little "sudo reboot"... then next boot, all is working well.

In addition, the only setup that enabled me to boot correctly on every try is, simply, to enable autologin (wich I don't really like for security reasons).

My case number: 335296057.

After 3 days, some technician from Apple called me and ask me details about the BSOD problems.

It seems that apple is collecting information and start to face this problem.

He told me that apple will collect my RMBP to further investigate this problem and will give me a new RMBP as an exchange. And he told me he will call me again a few hours later.

Currently I just enable the auto login to avoid BOSD, this definately works for 4 days and no BSOD any more.

Since the apple technician called me, I tried to reproduce this phenomenon by disabling the auo login. I perfected reproduce this problem and record it with my iphone 4s.

I have uploaded on youtube:
