OS X :: Intel IMac Not Starting Up?
Oct 1, 2009
did a quick search on Apple, and here but didn't turn up much of anything useful. I've got a friend with an iMac that won't boot up. Pressing the power button doesn't seem to do much of anything. I've tried unplugging the power cord, and re-plugging it, but alas, I got the fan to rev up for a second and then blahh, nothing again. It's a 20" model with the black bezel. Not entirely sure of the system specs, I only got a couple minutes with it last night. Do these machines have any common problems like this?

Upon starting My Intel iMac, it stops at the Apple logo. I have restarted it several times and tried to hold down the "r" key while starting to enter the restore mode...nothing but the Apple logo. OSX 10.7.5

My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.Â
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.

I have a G5 iMac - 2.1 ghz, 20", 250gb hd and 3gb ram, but it has been having problems starting up and it is also going to sleep midway through a task or at random times totally unprompted.
It now almost never starts up first time (I keep the iMac mains power lead always connected and the mains electricity supply turned on at all times now)- sometimes I will get the 'Start-up Chime' and then the cooling fans start spinning very loudly and then after a few seconds the iMac stops the start-up routine, but often when I try to start-up I don't even get the 'Start-up Chime' and I have to leave it for some time before trying again.
I can also now only get the iMac to run as a Firewire Target Disc by starting up with the T key held down and then using an old G4 (400mhz) Powerbook Titanium as the screen/keyboard by using the iMac HD as the startup disc for the Powerbook but this is obviously just a temporary work around.
I have also tried backing up all my data, and reinstalling the Mac OS X onto the iMac but the iMac still will not start-up normal and I still have to use it just as a Firewire HD.

I got my new 24" iMac ~2 weeks ago, and it's AMAZING compared to my MB... Except the fact that the computer will randomly wake up or start up in the middle of the night. The first night I had it home, it turned on 7 times! The next night, it did it once and I turned it off. It stayed off. The day after that, I turned it off when I went to bed. At 4 AM I hear "DONG!!!!!!!!" Ugh. I get up, and turn it off, only to have it start up at 5 AM. x_x I spent the next day looking for answers, I turned off wake for ethernet network something, and turned off screen sharing, quit all programs, and turned off the Airport card. Still, at 3 AM, it wakes me up. I turn put my jacket over it so I can get some sleep. I've been fighting it every night. I'm tired of it. Yesterday I reset the SMC and PRAM, and it still woke from sleep.

I recently replaced my internal hard drive in my 20" iMac and it worked beautifully for about a week.Then, suddenly it started making a horrible clicking noise upon startup or when waking up from sleep.It goes on for about 10 minutes and then eventually tapers off and quiets down.But it happens every time I start up the computer or when I wake it up after it's been asleep for a while.I don't seem to be having any other problems with the functionality of the computer.Everything is accessible and working OK on the computer.I am just worried because many years back when I had a PC the internal hard drive failed after I heard a similar clicking noise, although it's been going on for a few weeks on my Mac without worsening, and my PC hard drive failed within a couple of days of the start of the clicking.
Is it possible that this is a fan or some other internal mechanism that possibly got jarred or moved slightly when I replaced the hard drive?Or a bad hard drive?I don't really want to open up the computer all over again but at this point, I suppose I have to.I am just not sure what to look for when I do.urls...

When I start my iMac, a few programs start along with the computer. I don't want any programs starting by default. I have reviewed the Preferences of these programs, and see nothing to uncheck regarding auto startup. And I don't see anything related to this in System Preferences. How I can start the computer without programs starting with it?

I have an older imac and after installing a mac update I was required to reboot after install.
It froze at the beginning of start up at the apple logo. The spinning icon is the only indication on the screen as if it was working on loading. There is noise from the imac as if it is starting up but nothing happens.
I have let it run hoping it would eventually start. But nothing.
IMAC DV400 is the model number.

has all my art course work on. When pressing the power button there is no start up, screen stays black. There is a noise from the Disc Drive, when you put your ear close you can hear the Disc spinning, occasionally it starts to make a loader noise like its trying to spin to full speed maybe, but stops before it can. Green light can be seen from bottom, tried unplugging and waiting, tried pressing the cmd R-P keys down at start up. Also tried as suggested on the apple website to use a paper clip to manually eject the disc.

I just got back home and I move my iMac's mouse to turn the screen back on. It turns back on and I notice the whole computer is frozen except for the mouse pointer (the dock wont zoom or anything). I hold the back power button to force it to shut down, but the machinery inside doesn't quite seem 100% settled yet, I can just barely hear a little fan moving, but then it too stops. Upon turning it back on with the backbutton, it makes a clicking sound over and over again (sounds like it could be the HD?)
It keeps making this sound then pauses, and does it again. It freezes on the white screen where the grey apple would usually appear. It's stuck on this white screen and keeps clicking, until I'm forced to shut it off from the back again. I've tried shutting it down from the back, then unplugging the power, but that hasn't done anything either. I'm using... Vista. (the specs of the iMac are in my sig.)

I have a problem with my iMac which is running OSX 10.8.5. I think the easiest way to explain this would be to just give a simple example. For example let's say I have Excel and Word both open. I shut them both down. Then I completely shut down my computer. Power off. I go to bed. Next morning I boot up and guess what? Word and Excel are now running again, just as if I had never shut them them down.

I have a 2006 Intel Macbook with a crashed hard drive. I'm kinda broke right now, so instead of buying a new hard drive I loaded ubuntu 10.4 onto an external hard drive (USB) and tried to boot the macbook from it. (Failed). I hold down option to launch Startup Manager and all it shows me is a cursor (no drives). I know the external drive is bootable because I a) booted the laptop from a LiveCD and used it to create the hard drive and b) I booted a Dell from the external. I've tried moving the drive to a different USB port, but no chips. I don't have anything else connected to the computer.Â
my question is: Can I boot the macbook from the external hard drive if the internal hard drive is shot?

MacBook, Mac OS X (10.4.11)

So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.

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. Â
Here are the things I've tried.Â
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 nothingÂ
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.Â
