OS X :: Intel Imac Won't Boot Up And Is Freezes When It Does?
Jan 7, 2010
I was working with logic pro 8 on a project when the APP crashed. Then, the whole computer became real slow. I couldn't open anything without getting the spiraling rainbow circle for at least 3+min and even then the app wouldn't launch. So I shut down normally, which took a while.
After I left it off for about a min or so, I tried to boot again just to get stuck on the gray screen with the apple logo. I did some research on my phone (since I currently don't have internet because I'm moving this week) and found out how to reset the pram. I tried it, and this time it got all the way to the blue screen where it got stuck. I tried resetting the pram a second time to finally get to the log in screen but everything was going very very slow. Unusable type of slow. Opening a new finder window took at least 2 mins and everytime I ran my mouse across the idock, it would freeze.
Got my 24" 2.4GHz iMac on release last year, with Tiger. Installed Leopard on it on release day.
The problem I have is that ever since a botched Boot Camp installation I've had endless problems with certain applications hanging during their startup (notably Image Capture) or refusing to quit (notably iTunes). Force Quit doesn't resolve these issues. Restarting doesn't work because Force Quit can't quit them so I have to pull the plug or otherwise force a shutdown.
Upon restarting I either get the grey screen that instantly appears, or, if I've pulled the plug and left it for a few minutes I can get to the Apple symbol but no spinner or any further start up action. Occasionally I get lucky, get back up and running, and all is well until the next crash.
All this started happening when I decided to try installing Windows on Boot Camp again. I've had it on here a couple of times since Leopard was released but usually end up deleting it eventually because either the Windows installation gets bogged down or I get bored with it and never use it. Anyway, this time, using the same discs I've always used (and yes, it's SP2, so it should be fine and anyway it's worked at least twice before) when I got to the 'restart to continue installing Windows' bit, I got the white screen and nothing happened. After an hour or so of praying and restarting endlessly trying to get a response, I finally got it to recognise my OSX installation and was up and running again. The Boot Camp volume didn't appear to be there and Disk Utility revealed zero problems whatsoever. Everything looked fine until these recurring hangs, refusals to quit apps and screwed up start-ups.
Any ideas? I don't have the expensive Apple support, but it's less than a year old! Of course, I realise that this means nothing to Apple, who seem to think I should pay a premium in order to have my machine warrantied by them for more than 90 days. Grr...
If I get it up and running I'm thinking I should just wipe the ENTIRE system absolutely clean and re-install Leopard and then use my Time Machine backup to put all my data back on (pricelessly valuable as I use the machine to work on my photography with), but I'm concerned that if there's a flaw in the System somewhere, a corruption, that installing the Time Machine backup will just reintroduce the error. On the other hand, if it's a deeply embedded and invisinle partition corruption from the bad Boot Camp installation attempt, that should be fixed by wiping the entire drive to reinstall Leopard, right?
I have an iMac Intel ( 2008 ) and a problem came up so I figured if anybody knew anything about this as we don't have the biggest support in Greece to be honest , to help me.I pushed the power button but it gets stuck on the boot screen after the "bong" sound but it shows a second apple logo next to the 'original' one but it is broken as extra pixels.
It's a 2.16 intel Core 2 duo with the ATI Radeon X1600 128MB video and I'm running OSX 10.7.3. It started happening on Snow leopard so I thought maybe upgrading to Lion would fix it but it has continued exactly the same. I've had an issue for a while now where the computer would just freeze all of a sudden. It happened after a few days at times while sometimes it happen right after a reboot.
Here are the things I've tried.
1. I upgraded to lion
2. I replaced the ram
3. Look at the crash log but found nothing
4. Ram mem check utility but it found nothing
I can boot the computer in safe mode by holding the shift key and it works perfect with no freezing but I loose audio support becuase I think it's not loading the audio drivers. Question is: Can I select what drivers I want on boot when starting in regular mode not safe mode in order to try to disable drivers until I find the issue? Is there anyplace else that I can find which driver caused the computer to freeze after a freeze/crash? If I can ID the driver is there a way to update/replace the driver if it doesn't come up in "software update"? I'm thinking it's the video driver becuase I would occationally get some weird things happening on the screen that I attributed to an older display.

Having some trouble with my iMac5,1 - Intel Core 2 Duo - 2.16 GHz. It's about 2yrs old. Symptoms include: 1 - freezing when I open, close or move windows too quickly, open too many windows and/or when I multi-task in general. Anything processor intensive is unreliable. 2 - apple mouse cursor shoots off to the side of the screen for no apparent reason and scroll button is unreliable. 3 - lines across the screen that resemble pixel drop-outs - they come and go. I'm still running 10.4. I've wiped out my hard drive twice in the last 2 months and started over from scratch. When I re-install 10.4.0, it seems to run fine. until I run the system updates. That's when my trouble begins again. I've also cleared out my caches and histories repeatedly. I've run the Disk Utility repeatedly. This is getting serious. My PC at work is WAY more reliable than my Mac. I'm considering switching back! I owned a G4 for 7 years and was very happy with it. Was the switch to Intel a bad idea?
Has anyone had a problem with their Intel iMac mouse freezing after it wakes up from being asleep. Check my sig for specs. In particular, we have a wireless mighty mouse and everytime you wake the computer from sleep, the mouse won't work. That includes taking out the batteries and putting them back in. Keyboard still works. Is the bluetooth going bad? Could it be the mouse? We're going to schedule an appointment with the Geniuses here in Memphis so maybe they can figure something out.
I have a problem with my iMac 2 GHz Intel Core 2 Duo (2 GB 667 MHz DDR 2 SDRAM), running OSX 10.6.5. OSX crashes and freezes all the time. Nothing works anymore. Sometimes it just freezes, and I can only move my cursor, but nothing reacts anymore. Sometimes the screen blacks (or sometimes blanks) out or shows the weird moving colours as shown on the photo I just took below: After restart, it often happens again and again. Then the iMac is fine for a couple of days, before it freezes again. Can anyone diagnose the problem from the info above?
My iMac started freezing at the login screen. I power up, the apple logo comes up (sometimes the blinking globe comes up for some reason) and then the apple logo flashes as if it restarted or something, and the loading indicator shows up for a few seconds. Then at the login screen everything looks normal (my picture is there and correct name of account is shown) when I type the incorrect password, the text box shakes appropriately. When I type the correct password, the loading indicator appears, the mouse turns into a beach ball, and it hangs until I hard shutdown.
I know it's not a hardware issue because I just booted from the recovery partition and was able to view all my files in terminal. I would rather not reformat the hard drive. Is there a specific file that may be corrupted that I could delete and mavericks would automatically rebuild it?
I was off of my iMac for an hour or two so my screen saver when on. I went to wake the computer and it was frozen. I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back. I let it sit for 15 minutes, then I tried to start the computer up again. Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it.
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
Ordered new RAM for my Mid-2007 iMac 24" 2.8 from Newegg.Crucial (2x2GB Crucial 200 Pin SODIMM 256MX64 DDR2PC2- 5300 Dual DIE CT2KIT 25664A C667)
I installed them both in their own slots, made sure that they clicked in.when I connect all the cables in and turn it on I get no boot sound.I decided to take one of the new ram out and installed an old one it boots up. It reads that it has 3gbs of ram.
can I boot from my HP iPod via firewire on a 2007 imac or an i7 MBP? in other words, do early iPods play nice w/ intel macs via firewire? the reason I ask is because I'm tempted by OWC's 40GB SSD sale and want to try SSD's without the risk that comes w/ surgery (save for the old iPod).
I know this is a fairly common subject matter but I have tried just about everything suggested but with no success. detailed below are my findings, I was wondering if anyone better qualified than me could suggest a diagnosis?
What does it do?
I hear the fans and hard drive and see the white/grey boot screen with the apple logo and spinning cog. The cog will spin for anything from 5 - 30 seconds before freezing. Some disk activity will continue for a short time afterwards before everything grinds to a halt?
I have an aluminium cased iMac (2.66GHz Intel Core 2 Duo) running OS 10.6.8.
Recently I have found that sometimes the machine will not boot - I get the normal chime, grey screen and then the flashing question mark icon. I first noticed the problem a few months ago when restarting after a power outage had occured whilst I was using the Mac. After a couple of tries the machine booted and so I thought little more about it because in usual circumstances when the machine was shut down correctly it started as normal and behaved perfectly. However, after another power outage over the weekend the problem has become much worse.
I have tried all the usual things like trying to boot up in safe mode and recovery mode but with no success. The only way I can get the Mac to boot at all is to simply keep powering down and powering up again and hoping that it will spring into life. Once it does boot the Mac behaves perfectly.
I have an 10.6.8 universal system disk and I got the machine to boot from this disk. I then tried to perform some diagnostics on the hard drive (320Gb) but when I got to the pane that shows the available drivesthere was no drive to be seen.
After a lot of tries I have got it to boot off the hard drive since so, I have been able to back up files that weren't archived to an external drive.
The problem is that the mac will not boot period.When I press the Option on start up, it takes me to a screen where I could select to boot from the Macintosh Hard disk or Recovery 10.9 disk.Choosing either of these still does not boot up the computer.
I think that the hard disk is damaged but what I do not understand is why I can still get the option to choose the Hard disk or the Recovery disk.I am waiting to hear from Apple Support on when I can take my imac to the genius bar and I was wondering if there is anything I can do before then. Intel imac 27-inch bought refurbished in November 2010 with imac apple care.Intel quard core processor, 4 Gig RAM, 1 terabyte HD
My beloved iBook 1.33 wont boot, has flashing? and freezes when I try to boot from original CD with a bunch of vertical lines. I ran the diagnostic DVD and it says Invalid memory access. I removed the external ram chip for computer and still get same error. I also zapped PRAM, reset NMVU (whatever it's called). I already have the iBooks case open and willing to try anything.
I have downloaded the RC version of Windows7 64bits. I burned a DVD with 1x speed but when I tried to boot via DVD (pressing option key) it shows 2 option for DVD, Windows and EFI. I tried both and none worked. The Windows version starts and a DOS menu appears with 2 options which doesn't show what it is and then it freezes. The EFI option freezes imediately on the boot screen.
My dads MacBook Pro started acting weird first the screen would freeze up and the cursor could still move but there would be about an inch wide black line that would follow on top of the cursor wherever you moved it.
We thought it was a software problem so we booted it up off an external drive and it did the same thing after a few seconds of loading the finder, now it won't even boot, it loads the white screen with the apple, then it stops at the blue screen where it usually shows the loading of everything, once in a while it will get past that but it freezes with black lines over the cursor.
I've tried zapping the pram and i've held the power button down till it beeps i've also reset the pmu, so im out of ideas.
I was using my mac pro 3.2 octo from 2009 without any troubles. Recently it started giving non stop trouble. I have 2 gb ram from the factory and another 2 from 3rd party. My problem is when I boot my mac I am getting some strange vague designs and it freezes. I tried shifting the boot hard disk from slot 1 to slot 2, booting with either set of ram, changing the graphic card slot etc.
We have some new Intel iMacs and have transferred some information from our previous G4 PM (one MDD and one Quicksilver) to the new iMacs. For some reason the G4's will now not boot up and kernal panic on the gray Apple boot screen. This has happened to all the G4's we have in our office. They are running OSX 10.2.8 and the iMacs are running OSX 10.4.4. We can still mount the drives from the G4's using FireWire Target Disk mode.
I have tried zapping the PRAM etc but they still wont boot. I have also tried running the OSX 10.2 Installer disks to try and reinstall OSX on the G4's but the installer cannot see the drives?
I tried running the disk utility. It finds the hard drive but wont let me verify/repair permissions (the option is grayed out). It will only let me verify/repair the disk, but it finds no errors. The installer cannot find the disk at all.
We have more than one hard drive in the G4's and the target disk mode will only mount the system drive, it doesnt see the others, so we cannot retrieve out information. Whats going on. Never had this problem before.
Anyone have any idea what is wrong. Never had this problem before using the FireWire transfer.
I try and start my computer, it gives the boot sound, comes up to the password screen, accepts the correct password, gives a white screen, then returns to the password screen. I am running Lion 10.7.4 Any solutions before I call and take it in to Apple?
