OS X :: IMac Not Getting Past Blue Screen
Jun 19, 2009
I am running OSX 10.5.7. Installed it several weeks ago. This morning, the computer was acting up a bit. For instance, in my wife's account, I couldn't access our shared iTunes library, getting the error saying it was locked. When I rebooted, suddenly I couldn't get into the machine. It just hangs on a blue screen. I've tried booting with the shift key down, and that didn't do anything. I also tried cmd-s, but don't know what to do with that at the prompt, and cmd-v, which works fine, but just dumps me into the blue screen again.
I have a bootable FW drive, and I can boot fine off that, and even see the internal drive. I've opened files on the internal drive -- it all looks intact. But I still can't boot from the internal drive. I've tried Googling for solutions, but if you google "hangs on blue screen" or bsod or whatever around OSX, you get a bunch of hits related to installing 10.5.7, which isn't my issue, and you also get articles from 2006 and 2004, etc. I was hoping it was some sort of permissions thing, but I am not really sure.

My imac will not boot past the blue screen. It crashed whilst loading a new application which I downloaded from the mac website, had to force a shutdown as it wasn't responding, and now it will not boot no matter what I try. I have searched for answers on the forums but my mac will not respond to any keyboard commands even with the installation dvd inserted. I don't get the startup chime anymore either.

I hardly ever turn off my Macbook unless i need to - I just close it and use it whenever i need to. I let the battery run dry as Apple suggests to do every now and again, and turned it on the next day. It started to boot and took a little longer to get past the grey apple logo and loading circle and then froze on the blue screen. I can control the mouse, but every few seconds it changes to a darker blue, cursor disappears but returns after a second or two. I've tried:
- Booting into safe mode (Same thing happens)
- Booting from CD and repairing permissions (Said everything was ok, same thing happens when I booted)
- Single user mode (used some commands from an Apple page and restarted)
I can however boot into windows perfectly fine, which leads me to suspect it's a corrupt log in item. I'd like to know for sure it's not a hardware problem so I don't have to take it into an Apple Store.

I am trying to reformat an iBook for a friend. Everything was running, but, there was no chime on boot. I logged into the machine, and was checking files and folders when it locked up. It actyally locked up while trying to run Microsoft Word. It now boots to a grey screen the the little "spinning" thing, and then, instead of going to the login screen, it just turns blue. It will NOT boot into Safe Mode, it will NOT boot to the iBook Install CD, I just get the same blue screen using both methods. I used Command-Option-P-R without success. I booted to Open Firmware and typed reset-nvram without success. I don't know what else to try. I am copying her files right now by booting into Target Disk mode, but, once I get that done, I still won't be able to boot the install disc to get the system wiped and reinstalled. What else can I do to correct this?

My ibookG4 won't boot past the blue screen. I have run fsck several times in single user because it won't boot in safe mode. Every time it comes back **** FILE SYSTEM WAS MODIFIED **** and never that the volume is ok. This blue screen problem occurred after trying to hook up a wireless router and changing settings in airport. If anyone knows how I can fix this.

I was updating the permissions on my osx drive and finder froze so I relaunched it and finder would no longer work, I got several messages about obscure things not being installed properly like "bluetoothkeyboard". I then restarted my iMac and ended up stuck at the loading screen. I've tried everything iveseen on the forum like fsck and using the install cd but nothing seems to be working
Ps, not 100% certain on my os, I knew it was snow leopard but not sure if it is 10.6.8 or not

I have one of the old blue PowerMac G3 computers, and I kept getting a kernel panic, so I reset the RAM and now when I start up the computer, it stops at the apple screen without even spinning. I've tried booting it in single user mode, and for some reason it doesn't make a difference what keys I hit while turning on the computer. It still boots to the apple screen.

At work, we have a 17" G5 iMac from back before the iSight was put in. We're an Apple shop, so we have the new iMac actually on the floor for people to try out. The old G5 this thread is addressing is up on a shelf, but we want to turn it on as a display model. We plug a temporary mouse and keyboard into it, but the machine never gets past the white Apple screen with the "I'm thinking" animation. After a minute or two, the fan turns on full blast, but the white screen remains without any signs of moving on. What is our problem?

I've got this little problem with my 2months old iMac i5 since this morning. Yesterday everything was fine, I Watched a movie and updated some software, nothing illigal or damaging. Today I tried to boot my iMac, It showed the apple loading screen, with some kind of loading bar under it. I thought he just had to do that because of the update, so I decided to make breakfast and come back to check on it. When I came back, the bar was gone, but he was still loading! (15 minutes later). So I decided to reboot. still the same problem. I decided to boot from cd to see if this works, to select the startup drive. First I tried to fix the hard drive, but it is unable to fix it. I don't care to format my mac, but would like to know if there are other options to try first.

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.

I have a fifteen inch 800 MHZ 768 MB ram iMac G4 and for some reason it won't boot up. The apple screen shows up, goes away and then the screen is apple-blue with the cursor you can move around. I left it on overnight and it didn't get past the apple-blue screen. What do I do?

I have an iMac G5 that is clearly booting up--you can hear the skype connection sound in the background--but I'm stuck w/ a blue screen. Tried P-RAM and other keyboard methods, to no avail. Took off back cover, seems as though only 1 fan is working.
Was able to connect iMac to my laptop via target mode, so it's truly a screen connection problem.

I am a Mac-newbie who recently switched from PC to Mac. I know a little about comps and have some experience with Windows and Linux. Now the Mac. I upgraded my iMac 20" (bought it used from a friend) from Mac OS X 10.4 to Mac OS X 10.5 and everything seemed to go according to plan until it came to the re-boot and the comp froze on the blue screen with the movable mouse pointer showing. I tried the apple key with s on boot and did fsck -fy and fsck -f a couple of times. It only shows "The volume MacC appears to be okay". Everytime I typed "exit" to go to the log-in window it still gets stuck on the blue screen. I tried to start it with the installation disk in the DVD drive but now it doesn't eject it either anymore. So, the situation is: I have an iMac with that wont go past the blue screen, with a workable mouse pointer and a stuck DVD in the drive. I am extremely frustrated especially since I do not have a second Mac to read the HD in the iMAc with and I don't have a backup system (except my PC Laptop). What can I do?

-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:.......................

My Imac has been acting up. When I restart the mac it takes forever to start up. It goes to the blue and stays there for several minutes and then will finally boot up. I am running Leopard on an Intel 17 in imac.

My iMac (which was bought in september of 2006) fell around 2 months ago and cracked on the left side of the screen. It wasn't such a big problem until blue vertical lines began forming around the crack and now spreading. Now I don't know what to do, would it be cheaper to get it fixed at an Apple store or can I replace the screen, and if so where would I be able to buy an LCD 15" screen?

Tried everything from archive and install (wouldn't read disk2 until the 9th try and ended up with 9 system folders). Then tried an Erase and Install. Still it refuses to boot. Get's hung up at the blue screen. Will only boot in safe mode. Now for the last few days even the startup chime is missing. Tried PRAM and NVRAM resets. no help. Won't boot from DiskWarrior boot disk either. Just hangs

I bought a Guardian MAXimus hard drive and it seemed to be working fine for the past few weeks. Now all of sudden when starting my Imac 27 I7 the grey screen takes a long time then it get stuck on the blue screen and stays like that. Some times after being on the blue screen it will goto the main page but it takes 3-5 min if it does. When it gets stuck, if I unplug the firewire from the back of the computer from the hard drive it boots up. Any thoughts, their tech support wants me to send the unit back with out doing any testing at home to see what the problem is, seems like a pain in the butt.
