OS X :: IMac Frozen Boot Up
Apr 4, 2009
My iMac just crashed. All apps except finder gave me the beach ball, and force quit wouldn't load. I cold-booted it and it is now stuck on the screen showing the apple logo and the pin wheel, except the pin-wheel doesn't spin!

I noticed my notebook running a little slower than usual so I took the usual steps, without much luck. I then verified and repaired disk permissions in Disk Utility. Tried to use disk repair but got a message that the disk was damaged and I needed to boot from an install disc and run Disk Utility from it. I put the disc in, chose it as my boot disc in Preferences, and ever since once I power up all I get is the chime and a blank grey dead screen. proceed or at the very least remove the disc from the SuperDrive

While using Mail, I got a message that there was an error with Mail and I needed to quit and reboot. When I re-opened mail, it prompted me to set it up and while it was reading the files, it froze. Subsequently, my Imac (OS 10.6.3? Snow Leopard) became frozen, i.e. my whole computer. I shut down using the back button (nothing else worked) and then restarted. I then re-booted using the regular re-start system. I was able to do 2-3 functions (the computer was super slow) and it froze again. After 2-3 repeats of the same procedure, it freezes after being turned off and on using the back button. I updated my software about 3 days ago. There was a major security update in that update. I'm waiting for a professional techy to call me back, but if you have any suggestions on how I should proceed, I'd be most grateful.

I have Processor 2.66 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3, Graphics NVIDIA GeForce 9400 256 MB, Serial Number YD******0TG, Software OS X 10.9.3 (13D65)   Did not have any problems until recently.  Now my finder is frozen.  When I open finder I see a lot of windowo all piled on top of each other and I am not able to click on anything and see my files. I read somewhere that Google Drive causes problems but can't find the article. I cannot afford to get rid of my files in Google Drive.  I do not have a lot of computer experience and am somewhat afraid I will do something that will make me loose a good deal of information on my computer.  Have the same problem when I try and access Mackintosh HD from my desktop. I have shut down and restarted computer.Â

I keep my iMac on at all times. It does have a screensaver - but no sleep enabled. When I travel I occasionally access it remotely. It is only about 2 months old and lately after all the (Apple) software upgrades, almost every morning I find it frozen. The only software that is set to run overnight is a Super Duper backup - but I have turned that off and it does not appear to be the culprit. Time Machine runs automatically. I searched and tried some solutions including repairing permissions and checking preferences. Is there a log somewhere that may identify what is causing the freezes?

It just froze on me about 20 min ago. All I was doing was listening to iTunes and browsing the music store. I looked at the temp of the computer and it seems kinda high, I don't know too much about this.

I downloaded Mac OS X 10.5.7 from the Apple website rather than using Software Update only to save time. I used Software Update to get 10.5.7 on my MacBook Pro and it took 35 minutes to download the package. Using the Apple website for my iMac, the download took about 15 minutes.
I then began the installation of 10.5.7 on the iMac. Everything went fine until it was time to restart. The computer froze on restart. I had to hold down the power button to turn off the iMac. Then I started it up and it began to load for quite a while (normal after an update). Then I logged in and went to "About This Mac" and it read that I had Mac OS X 10.5.7.
Obviously, this is an unorthodox way of updating. But am I safe with this method? Was it just a minor glitch?

2MHz PPC G5 iMac OS 10.4.11. Several attempts were made to login with wrong password. The iMac is now frozen on the login screen. Entries can be made in the Username and Password fields, but there is no response to "return" or "cmd" keys. The action buttons (sleep, login, etc.) are grayed out. Power button only puts machine to sleep, and it wakes up at frozen login screen.

When my IMac goes to sleep, the screen saver is "frozen". The only way to get to my login accounts is by "cleaning" the screen with my mouse. It's as though the screen is not refreshing itself after going to sleep and whatever the last image was, it stays. However, it's not locked up or anything. I just need to move my mouse around over the login accounts and it slowly clears away the screen saver so I can see where to click to log in. I've tried disabling the screen saver, but have the same results. Something is causing the last image to freeze on the screen when the monitor sleeps.

I was browsing the internet on my '08 iMac when the system suddenly froze immediately followed by the screen turning to nothing but vertical lines. I fear this may be an issue with the graphics card, but would anyone be able to offer any further insight?

I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM
In the second week the boot up times became very slow.
I would turn the machine on and get the chime within 5 seconds or so.
Then just a black/blank screen.
Eventually after about 10mins I would get a white screen then it would boot up normally.
Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).
I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.
I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.
But now when I switch it on just darkness.
I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.

I have a Imac PPC with a 2Ghz processor and 1GB of Ram. I am running leopard 10.5.8. Recently i woke the PC from sleep mode to find a blue screen with only the cursor working. Using the internet, I determined how to get the PC booted in safe mode. I have used all the disk utilities at my disposal along with onyx and cocktail to try and fix what I believe is a startup problem. I hae booted the PC in single user mode and tried the fskc codes, which i believe is just the same as the disk utility. Based on my computer all permissions are correct and there is nothing wrong with the HD. The PC still will not boot normally. I have even done an archive and re-install of Leopard.Â

I think it worked at one point, but sometime around the point when I set up Fusion with the partition, Windows Aero turned off and is no longer an option in the display settings. I installed this driver with the modded INF to see if it would do anything, but Aero is still not an option. I also have issues playing some games in Fusion, while they work fine in Boot Camp.

I'm using a 20" white intel iMac and cannot manage to remove a linux boot disc from the optical drive.At first, the only way that i managed to boot to the linux disc in the first place was from the Startup Disk menu in OSX. I could not even get to the Startup Manager ('opt' at boot) or boot straight to the disc ('C').Now i'm in a position where no matter what i do, the system boots to the linux disc. I cannot even force the startup into OSX to try to eject the disc from there. I've tried holding all of these keys/combinations at startup

Back in August, I did an OS update on my iMac, and the machine wouldn't reboot. I was able to reinstall Leopard by booting from a disk, and all was well for a few more weeks. The machine seemed to run normal, with the exception of 5-minute-plus boot up times. But within a few weeks it stopped booting. I installed Leopard on an external HDD and figured I'd leave the internal alone until Snow Leopard came out.
A few weeks later when SL was released, I booted from the install disk, found the internal HDD, and went through the installation process. Everything went fine but the machine would not boot. I installed SL on my external HDD running Leopard, and everything was fine. I've since been running my computer off the external.
The internal HDD no longer shows up on the desktop, in Disk Utility, etc. I'm fearing it may have died. More worrisome, though, is my machine doesn't always boot up, whether from my external HDD (set as the startup disk) or from CD. By "doesn't always boot up," I mean most of the time when I restart, it just sits on a gray screen, nothing happens (even when holding "Option" or C.) Sometimes it will boot, but takes 20 or 30 minutes to do so.
I'm considering replacing the internal HDD, but am curious, does that seem like the issue, or might the failure to boot from externals and CDs indicate a more serious problem?

I have the CD version of tiger and am trying to install it to a recently purchased iMac G3. The Installer installs disc 1, resets, but doesn't boot up to install disc 2, it simply asks again to install disc 1. The Mac for some reason will not boot from the installed software and therefore I cannot complete installation. Can anyone figure out why the mac refuses to boot from the HD in order to install disc 2?

When I look at "About This Mac" it says that I have a 2.4 GHz Intel Core 2 Duo. I originally had two 1GB sticks. When I installed two 2GB RAM sticks, it wouldn't boot. Just for fun, I tried putting one 2GB and one 1GB stick inside, and it boots fine.
[URL] says that I can have up to 4GB: [URL]
But the guides say that it depends on if I have Merom w/ Santa Rosa chipset or not:[URL]
But I read somewhere else that even if I install two 2GB sticks that it will just ignore the power of the second one and default to 3GB.

I found this beautiful 17" eMac at a yard sale! it is pristine I fell in love. I went about removing the stuff left behind by the old owner. Now it does not boot.
After a while I get the question mark on a folder. I know what I did but not how to get out of it. I have no OS X disk to start it from. What do I do now? I did try to reset some things but no good.

I have a 15" Imac G4 I bought used off of Ebay. It was doing great and then I clicked to look for updates. So it downloaded a 168mb file to update 10.4 to 10.4.1 It automatically tried installing, but then said it couldn't install and that it was moved into the trash. So I took it out of the trash and dragged it on my desktop. Then when I went to turn the computer on, it only shows the grey screen!

In 2011, my iMac was sent to hell for a crime it most probably did commit. This Mac promptly crashed and caused the destruction of my WD 1tb External HDD containing my recently backed up files. Today, the iMac will not boot up.

iMac intel core duo...
My computer had 1GB of RAM, so I just bought a 2GB RAM card. When I installed both cards together i can hear the hard drive start up and then nothing, no boot up, just a black screen and the "sleep" light is just solid. I know both cards are fine because I tested each by themselves and they both started up and worked well, its only when they are both in at the same time does it do this. also both slots work because i tested both of them! I tried to do the PRAM reset and it doesnt work, and I tried to do it with one card in and then reset and then shutdown and install the 2nd card and still nothing. Please give me some advice, i am soooo frustrated!!

The string of problems I've encountered started a few days ago. I normally let my imac go to sleep by itself but, on this occasion I told it to sleep via the apple menu. When I awoke the imac the screen was frozen. No mouse movement, no clock movement, nothing. At this point I turned the power off and back on again. It didn't get past the white screen (before the gray with apple logo). I then tried resetting the PRAM, booting in safe mode, and booting from my os disc. Nothing worked.
After several tens of tries it magically booted. It stayed active long enough for me to back up all my data (transferring at least 100GB), reformat the hdd, reinstall leapord, transfer data back, and use it until I let it sleep again.
