Software :: Blue Screen Start Up - Can't Login From Darw
Dec 26, 2008
I created a new user the previous evening and shut the computer down as normal, now when i start up I get nothing but a blue screen no login in screen nothing. I tried going into the command as root, have done fix disk errors no problems there, then tried lunchctl load/Users/System/Library/LaunchDaemons/com.apple.... plist cant rember the bit in between. I did this from the apple website, but all i get is no file to load, so anyway continued to do ls users/ get the names and tried reseting the password for the login's and i get a odd error. I have no idea where to go from here, as i cant find the original discs, can i use mybrothers os x 10.5 discs to re-install and save the files i want to keep and do a clean install?

Today my imac done something wierd. When powering on it got to the blue screen before the password login and it just froze on the blue screen. I done a hard restart and rebooted a few times. Didn't do it any more after that.
Should I be worried? It's only a few months old.

My iMac G5 (running 10.4.11) freezes at the blue screen, after recognizing the mouse, but before the login window. Some form of energy saver must be working because after the blue screen dims, moving the mouse will brighten it.
Steps I've taken:
Hardware test - everything passed (RAM, logic board, airport, display, etc...)
Zeroed the computer (7 times) and fresh reinstall
I CAN boot up in Safe Mode, Single User Mode, and Verbose mode. I can boot from CD, Knoppix CD, and into Target Disk mode (thank god for this MacBook I'm on now...)
Here's the system log (I've edited in comments and out personal info):
// reboot and power on

I love customizing my Mac and tinker with its preferences so I guess I had this one coming, although it's my first major mistake.
I'm running Mac OS 10.5 and I downloaded a loginwindow.bundle from deviantart to customize my login window but I realized too late that it was for Snow Leopard. What I ended up doing was:
- I replaced the original loginwindow.bundle with the one I downloaded; and
- I replaced the original com.apple.loginwindow.plist with the one included above.
- Thankfully, I made a backup of the original files which I kept in my Documents folder.
I then logged out and ... the login window never appeared, just a black blue screen and that round loading thingy at the bottom. I'm sure that's the only cause of my problem. (If it helps, I don't have autologin enabled, so I have two accounts to choose from before I can login.)
I've tried booting in single user mode and in safe mode but neither works.
I've narrowed down my options.
1. Use some commands in single-user mode to replace the new loginwindow.bundle and loginwindow.plist with the old ones, which are in my Documents folder (like in Terminal). Thing is, I don't know how to do this, if ever it's possible; OR
2. Use my Bootcamp partition (thank God for Bootcamp!) to manually do the abovementioned option with Transmac, which I already tried. Unfortunately, I can't write to my Mac OS partition since it's read-only, which leads me to the problem of having to change it to read-write via single-user mode.

My Mac OS x is stuck on the blue login screen. I have tried unplugging, cmd-alt-p-r which still takes me to the login screen, held down until I heard the chime three times as suggested but went to login screen. Tried going in to safe mode by holding down shift key at start up still took me to login screen. Tried to fix with boot disc and nothing comes up. By the way I wasn't really doing anything. Was checking my emails but hadn't even clicked on one when the screen totally froze. When I powered down it came back to email page. I had to force a shutdown several times and no can't get past login screen.

After what seemed to be an improper shutdown my Macbook will not boot. I have tried using fsck to no avail. Booting to the leopard dvd causes it to restart. Flashing PRAM doesnt seem to help and it will not boot into safe mode.

I have faced some known symptoms of a problem for which I was not able to find any sound resolution. I have an account with which I am unable to login. When I enter login details for a session, the system immediately kicks me out showing a blue screen, logs out and goes back to the login window. An interesting observation during a sudden logout is that I spotted a vague image or window of an open application (probably Finder) at the background which is like 95% transparent in comparison to the Mac's desktop and therefore barely visible. The white-ish edges of that window is more distingushable though for a short duration.
I can ssh to this username and work remotely. But there is another username which has not been affected with this issue and works fine. The console logs show that loginwindow process is crashing everytime. Look at the output below. There have been notes with similar effects but with specific causes (e.g. MS Excel 2004 inc Rosetta, Blootooth peripherials, eBook Studio, Photoshop CS3 etc.) which might be related cases.

I have already tried booting in Safe Mode, deleting loginwindow.plist without success.

Path: /System/Library/CoreServices/loginwindow.app/Contents/MacOS/loginwindow

I've had a MacBook for about four months, completely standard version, no modifications, no nothing. It's been working perfectly. I've the latest version of Leopard and any other software update that comes with. Today I've been working on setting up a new user account entitled "Work" - for obvious purposes. I've copied my regular account's home folder as well as applications and such to make "Work" as much of a copy of my regular account as possible - let's call that account "Me".
And so I've mostly been browsing around "Work" trying to give it the same access to files as "Me" has - "Me" is an administrator, "Work" is standard - by changing access and privileges. I had some problems getting "Work" to save - when I would log out and then log in again, "Work" would have lost the preferences, e.g. Stacks and Dock settings. I also couldn't change the desktop picture for whatever reason.
So then I was going to log out "Work" to see if it still had the saving problem, and it lagged behind a lot, so I did the emergency-turn-off-by-holding-down-power-button-that-you're-not-supposed-to-do thing. And then when I tried to restart, it wouldn't............

Every time I restart my macbook it will take me to a blue screen and the mouse pointer will be in the top left hand corner of the screen. It will not start in safe mode. I've done the "fsck -f" I don't have a the snow leopard disk any longer, but I can of course obtain another if it is the only way to fix this problem. I'm at college, the disk is at home 8 hours away..and I want on my computer now. Sorry for my lack of intelligence concerning this issue as well as the OSX as a whole, this is my first Mac and I love it!

I'm runing a Mac 10.4 Intel lap top. Its been running fine, but today when i shut it down it stayed on this blue screen. With out thinking I held down the start button and it shut off. I figured something was wrong, so I tried to start it up. It makes the start up noise and goes to the gray load up screen... then just shuts off.
Does anyone know whats going on?
And is it possible for me to get files off my hard drive? I've been in europe for 4 months and haven't backed up my photos yet, so I'm really nervous I just lost it all

My macbook air freezes on a blue screen on startup. I can see the cursor, but nothing else happens. Before this occured, the colourful "spinning wheel" used to come up with almost every application that I ran (for instance when writing documents).

I just started my iBook g4 up and after the initial grey screen with the spinning thing and apple logo, it just stays at the blue screen straight after that. I have left it for ages and it is still there and I have tried several times now. Does anyone know what the problem is and how I could fix it?

I have a 3 yr. Old mbp running tiger 10.4.5 and suddenly I had problems. I had leopard on her and she started having strange distortions while in safari which didn't extend to the desktop. So I did a clean install with orginal tiger disks and then I got the blue screen on start up. All hardware utilties and did fsck and all say HD is okay. Reset pram, checked battery and reinstalled ram and only able to safe boot and get into Hd but now it says no airport card installed. It's not running right to say the least. I read somewhere to check log in items in pref. Under Accout and it doesn't show any. Any ideas greatly appreciated. Also since this problem the cursor appears within a horizontally striped rectangular box like a half inch in size.

I have been running low on memory space for a while and just recently I turned my laptop on and all I saw was a blue screen. Fortunately there was still a bar on the top of my screen and I was able to access Safari by selecting the apple icon->Recent Items->Safari. I still cannot see the time or any of the other features. Safari seems to be the only application I can open, my itunes won't open and neither will just about any other application.

I have been getting blue screen which flashes about a second (once) at the start-up apple screen, but it is not stucked, it jumped to log-in screen immedaitely or rather normally. However I do understand that it should not be a normal start-up because when I just bring this mac home I do not have this problem before.

-Got the iMac refurbished in mid-2010 (2009 iMac i5)
-Originally planned on mainly using Windows, so I partitioned the drive to 750gb for Windows and the rest for OSX
I eventually got fed-up with certain things about both Windows and certain limitations/glitches within Bootcamp itself and decided it was time to go OSX, and use the machine properly in all it's Apple glory.
I removed the 750gb of the Windows 7 partition, restoring the whole thing back to OSX. At this point, my computer seemed to be working fine still- OSX would boot up in about a minute or so, nothing that seemed out of the ordinary. After that, I still wanted a small partition with Windows 7; so I partitioned 100gb of my drive and proceeded to install Windows 7. During the Windows 7 installation, as had happened the first time I installed Windows 7 with Boot Camp, I got the "Black Screen" issue. If you are unfamiliar with the issue, see here:.......................

When I press the power button on my eMac, it takes extra long on the gray screen with the Apple logo and the spinning gif, then takes about two minutes on the blue screen with just the spinning gif, then goes to a solid blue background, with a functional cursor, but no OSX. I've tried trying to eject the CD tray at all points in the startup process to put in the Mac OSX re-install discs, but it doesn't respond. What should I try before sending it in to an Apple store or Cupertino?

I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?
What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.

My IBook G3 will not start up. I can get the gray apple screen with pinwheel and then after a really long time it will go to a blank blue screen. A couple times it went to the login screen instead but in the user id it says "other" and when I try to enter my username and password it won't recognize me. I am a college student and one of the Apple geniuses here did a check of my hard drive and it checked out okay. We were not able to get it to start up in safe mode; it seemed like it was starting in safe mode but then it came to the login screen and would not allow me to login with my usual information. I was able to start up in single user mode and run fsck which found a couple things and after another fsck it said everthing was fine. But, it still gets hung up at startup. When I try to boot from the OS X installation CD it doesn't seem to be booting up with it, it only goes to the screen to install OS X. According to the directions on the Apple support site when I insert the CD and start up holding down the "c" key it should start up and then I should be able to repair permissions but I can't get that far.
