black screen after login, Mountain Lion on Macbook Retina

For it happened once you can see it here. I uninstalled gfxCqrdStatus and disabled Guest and it hasn't happened again.

I did install gfxCardStatus again and still no black screen. Even when I'm running both win7 and win8 on VMware and I close the lid and open it again.

I have to mention i use best for retina and don't have autologin.

I already filled a Radar when I first noticed this in 10.8.0 😟

Also noticed that this does not happen to me when i reboot my mac with the "Reopen Applications on next Login" button checked.

Went in Store today aswell and tested this bug on the "Hands on" MacBook Pros (retina) and was able to reproduce this on the 10th or 15th reboot. I asked a Genius about it but they couldn´t really help me.

I just discovered this discussion and can only confirm that it happens to my retina machine as well. For what it's worth, I tried the method of running it on best/retina resolution and have not had the problem since. I have not disabled automatic login. I have not disabled automatic graphic switching. I do have checked "close windows when quitting an application." Of the multiple combinations of solutions I've tried, based on what I've read in this discussion, the resolution setting sure looks like a major culprit.

MacOSX 10.8.1 MBPR. Since I set the automatic login I did not have the problem. But this is only a work around, ****!.😠

For those who have to turn off "disable automatic login," I have a somewhat awkward workaround that still requires some kind of login procedure upon startup. I use a simple little program called "Sleep Display," which you can download at

Althought the site suggests it's meant for Leopard, it still works in Lion and ML, and it works on my MBPR. I put it in the "Login items" in the "System Preferences/Users & Groups." I also set "System Preferences/Security & Privacy/General" so that it requires a password "immediately after sleep or screen saver begins."

Upon startup, it will activate, and your screen will go black. Simply press any key, and it will ask for your password. Thus, if someone still wanted to get into your machine, they would have to enter a password. At worst, they'll briefly see your desktop and startup items before your screen goes to black. It's not the most elegant solution in the world, but it will allow you a password protection option.

I've lost my ability to switch to the max screen resolution of 2880x1800 and the rep I've been speaking with believes it's related to whatever is causing the freezing, has anyone else experienced this?

On a side note, I'm heavily considering downgrading back to Lion, has anyone else already done this?

Resetting the PRAM and SMC seemed to fix my black issue when logging into my user account...for now... It hasn't happened since I've done it. I've tried rebooting my rMBP several times to without issues so far.

I downgraded to Lion with lots of problems. Mountain Lion changed a lot of infrastructure to the drive. I eventually had to downgrade to Snow Leopard and then upgrade to Lion. Finally everything is working again on my Mac. Thank god for backups. I will be staying at Lion with this machine and will not be going to Mountain Lion even though I purchased it and wasted my money. Bottom line is...nothing in these discussions really matter if you can't see your friggen screen.

I need to offer my apologies to this group.

Recently, I posted a message here stating that after talking with an Apple Executive, I was told that Engineers have solved the Retina Macbook problem and will be issuing a fix.

That now turns out to be incorrect.

I spoke with the same Apple Executive again yesterday on the phone, and it seems that there was some form of miscommunication on the topic.

Fact of the matter is, Engineers are still working to solve the problem, but have not yet come up with a fix.

If and when they do, that fix will most likely be offered through a standard Mountain Lion update.

I realize this is not good news for any of us, and really, I feel bad that I gave everyone the impression that a solution was around the corner.

I did ask the representative if, after a few months no fix is found, can the laptop be returned and refunded? I was told that in cases like this, most likely that can be done with no problem.

I am going to give Apple a few months to come up with a fix. If there isn't, I will simply return my Retina Macbook.

My apologies again.

I filed a bug report on this issue, and just heard back from Apple, they had me do the following, which worked for me (even while running gfxswitch):

1) Launch Terminal or ssh into the machine

2) Execute the following command:

sudo defaults write /Library/Preferences/com.apple.loginwindow DBLogging -array Process Users OpenDirectory Autologin FUS

Hope that helps!

Can someone decipher what this command is intended to do? Just by looking at the word autologin, im hypothesizing that it just enables auto login...

Has anyone been updated by Apple recently? I don't know about you guys, but I'd really like to get at the very least a rough ETA for a fix. The idea of this being put on the backburner irks me, considering I just spent 2k+ on a machine that can't even boot up properly with login enabled. I'd refund this thing if I was still within the return window...

Read 3 or 4 posts up.

I updated everyone that Apple does not have a fix for this.

Engineers are working on it, but there is no fix in sight.

I read it, but I'd like to see what everyone else says as well because it seems like the reps are telling different people different things.

I have just started experiencing this problem also. After entering my pw at the login screen, I get a black screen and then just frozen. If I hard-reboot and then login to Guest account, logout, and then login to my usual account I can at least get in... but then after a few minutes (seems random) suddenly a freeze, and/or a spontaneous reboot. I rebooted while holding down the D key to run the Apple Hardware Test and it came up with this error:

"Alert! Apple Hardware Test has detected an error.

4HDD/11/40000000: SATA(0,0)"

I ordered the machine in June and took delivery July 18. I had no problems until just today. Strange. I have an appt tomorrow with the genuis bar at my local apple store. I'm hoping they will simply replace it ... but as it is a CTO machine there will likely be a delay.

So disappointing that such an expensive new thing fails so soon.
