black screen after login, Mountain Lion on Macbook Retina

I have not experienced any black screen after login for 6 days now since resetting the PRAM and SMC .... Prior to that, I was getting the black screen about 50% of the time. Hasn't happened since if anyone READS. It doesn't hurt to try resetting your PRAM and SMC. Google the procedures.

Great...Just..Great...After installing all my software, my first ever appple computer "The Macbook Pro Retina". I also now experiencing the black screen after login. After 3 days of use. Come on Apple. We have paid dearly for the hardware and now it can not even boot. What a disappointment. I know there is nothing constructive in this reply but this is just bad.

FYI took it to the apple store today, genius bar appt. They took it in and will replace the logic board AND the SSD drive. yikes. Hope to have it back in 5-7 days. Warranty repair of course but sticker price for those 2 parts alone was around $1700 CDN. double yikes.

I tried a variety of the solutions here, and the Terminal command provided by HoratioSalazar has worked for me. I've shut down and rebooted my machine a number of times in the past few days; the problem would have shown up by now. I'm optimistic.

Hi HoratioSalazar

HoratioSalazar

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!

What is this command supposed to do ?

I actived the FileVault encryption and now it's working fine ....🙂

For the first time in someting I cant count. I my a succesful login on my account whitout going to the guest account first.

HoratioSalazar posted fix made my day 🙂

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

Btw.

The resetting off the PRAM and SMC did not help.

Thanks for the help.

Thanks for the info, i too have discovered this for the first time. Got my macbook retina on friday and had shut it down for sometime and turned it on and had this problem! Just adding my name, so hopefully Apple can take note of all of us on here!

DAAAMMMMNNNNN 😠 after 3 succeful login. Now i`m back to BSOD. (Black screen of dead) Got it from some other sites.😐 Apple this is a major problem, try to google and you will see how many is faceing this problem, and it does not help switching the hardware. It is you software Mac OS 10.8. See you tomorrow.

q4y2, active the FileVault encryption and bye bye the issue

Hi MUNEcraseur

I´m all new to Mac OS X but is active the FileVault encrption not achieved by this command.

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

After that it asked for my password and I enter the command again.

That was what I did in the first attempt and after that i made 3 succesful login og then it did again go back to the black screen on my four attempt.

q4y2, no this command dont active Filevault,

Look at this link:

http://scottlinux.com/2011/05/20/enable-filevault-in-os-x/

Ooo 🙂 Thanks...

I will try that...

The command definitely does not activate FileVault, since mine was still off even after the command. All I know is, the Terminal command

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

has appeared to fix the problem for the past several days. Of course, others have reported other methods that seemed to work for a few days, only to have the problem recur. Fingers crossed.
