Desktops :: IMac Won't Start Up?
Jan 20, 2010
I'm new here, but not new to the Mac world. I own an intel iMac and while I was attempting to restart it on Sunday night it went into a gray screen with the box asking me to shut and restart in several languages. I did and still get stuck on that page. I did a PRAM reset and that didn't work. So I used my start up disk to get to the disk utility and my HD is fine so I used an external drive to install the OS on it and reboot from and reinstalled from TimeMachine (only problem is the last time I backed up was 5 months ago)Again I checked my internal drive and everything seems okay, but I cannot reboot from it. BTW, I've OS 10.6.2,

I have a 20" Intel based iMac (model A1224) running Snow Leopard. It is just over a year old and only had the original Apple keyboard and mouse plugged into it. Today when I tried to start it I got only a blank gray screen. I tried all the keyboard combo start-up suggestions in the Apple help screens, unplugging/replugging everything, and booting with the Original disk and the Snow Leopard disk. A couple of those attempts produced a minute of the gray apple logo screen, then back to blank. While the disks were in it did sound like it was trying to read them, but spit out the disks after about 5 minutes.

I have an iMac G5 iSight. When the power button is pressed there is no sound and a white light flashes, but nothing else happens. I tried the power reset method and replaced the power supply, but the same thing happens. The white light just keeps flashing.

I have a G5 dual processor ((I think its a 2.5) running Tiger. I had it stored for several months and when I brought it out it won't start.. No response at all to pushing button..
Cord is good as it will power my display.

Something bad going on here. Dead hard drive(?)
Current status is...Cannot turn on, screen is dark. Blue light on power button stays on. Can't restart after holding it down...Red light inside box is on. Read that it might be air deflector trouble, but that's not it. Opened box removed plastic and returned it...another red light lit , then turned off. 1st red light stays on.
Before the above began, a restart would end up in a hang at the end of the progress bar. Ran Disk Util from Install CD which showed errors: "Volume Chk failed...HFS Volume needs repair". Ran FSCK whick said it fixed all. Ran Disk Warrior afterward b/c still would hang at startup. Says all now OK...but NOT! Have tried saving files thru Disk Warrior...but now, as per above, cannot get it to start up. Or turn off...
Would like to get it lit to save any additional files if drive is near the end...

I am using Mac 0S X Leopard, mac mini and facing the following problem:
1) System is taking too long time(10 - 15 min ) for start up and shut down.
2) It is asking every time to set up the current time as and when the system starts every time.
3) When accesing the system preferences , it gets crashed when using index Spotlight.
4) Finder gets relaunched itself for every 60-90 seconds when accessing folder Applications or Utilities etc..
5) The Spotlight is indexing itself, When i tried to stop the indexing of the spotlight using system preference, it gets crashed.
My system got its logic board replaced by the apple once.

My Mac attempts to start up and automatically shuts down on it's own. It continues to start and stop for several minutes and finally boots up. Once it's up it works OK. I've had it in to the Mac store and they tell me it's probably the power supply, but after leaving it on all weekend it seemed to work OK so they didn't do anything. After I brought it home it is still acting in the same way. It's only on trying to start up that it cycles through the start - stop action. Once I turn it off it's the same problem on trying to start again. Does this sound like a power supply problem?

When I get to the step that says "Start Installation" the screen goes black and says "No Bootable Device"
I have the Tiger disk in but nothing works.

When I start my iMAC (OS X) there is a good chance that it WILL NOT pair with my Logitech M555b (Bluetooth) mouse. It IS set to be "discoverable." The Apple mouse's trackball was a constant problem; it had to be cleaned often. Changed to the M555b and now I'm being punished by the MAC gods for my infidelity.

Have a 17" G5 iMac iSight (OS 10.5.8) that works normally for several hours and then the CPU temperature suddenly spikes and the computer shuts itself down. When I check the Temperature Monitor (application) history graph, it shows normal temperatures and then a spike. There are 3 fans and I don't know which is failing or whether there's something in the temperature sensing that's gone haywire. My only solution is to do a forced restart. By this time, things have cooled and it will work for several hours.

Recently, my iMac (Intel Core) started to slow down the longer I use it. Applications take ages to launch. Sometimes even opening a folder takes a long time. I have to force quit more and more times. I also have to literally pull out the plug when it just hangs. this is especially bad when it wakes up after I put it to sleep mode.
Is this a RAM issue? I'm running on 4GB RAM.

my iMac ejects blank discs when I try to burn music in Tunes or when I insert a music CD to play it.The disc spins around for about 15 seconds, then it gets ejected. I made sure the surface of the discs were clean and that I was burning from a "playlist," all to no avail. I was successful at playing a movie in iDVD, though, so I'm baffled.

My mother-in-law has an old Blueberry iMac which works ok except it won't connect to the internet/LAN. It is the computer, because the cable that used to connect the iMac to the internet is currently connected to a different computer and it works perfectly. The iMac runs Mac OSX 10.3.9. Has something died inside the iMac?

The displays on my flat panel iMac G4 (2003) suddenly have gone 'red': sometimes it will return to 'blue' and be ok. Is this a dying flat panel or can I fixit?

I am tech support for an Elementary-Middle school with an all Mac curriculum. We have been this way for just about 4 years now and our first model iMac 17 inches are no longer under warranty.
We have three iMac 17"s that don't work properly, here's the rundown:
- The First works properly fine but has a bad DVI port (we run SMARTBoards and require them for most of our classroom computers)
- The Second has a bad logic board, we don't have any other information about it
- The Third has a broken display, we're pretty sure everything else works on it.
We don't have applecare support on these three and are interested in turning them in to two (hopefully) or one working model for a teacher.
Any ideas/suggestions/resources?

I have an Imac at work, and it is agonizingly slow. Plus Photoshop CS2 is breaking up images so they are unworkable and is corrupting them. The hard drive says there is 202 GB available so -- is this a scratch disk problem and if so, why isn't 200 G enough? Does anyone have any help as to what I can do to speed this up? I have ordered (or are ordering at some point) another stick of RAM - but I am quite sure the problem is not going to be completely solved with that.

I have a late 06 early 07 intel imac. My problem is I recently purchased a 1 tb Seagate external hd and the imac recognizes some folders and their contents, like pictures and a couple others but will not recognize the contents of my movies or music folders. Now I copied all of my files from a wd elements 500gig and that worked perfectly with my imac. just can't get to my music or movies. Now, I can plug the seagate back into a windows pc and it works perfectly, so i know my files are there, but love to use my mac exclusively. Also running 10.4.11

For the past few months i've been having issues with my imac 2.66Ghz 24 inch. I'd say almost half the time when i put my imac to sleep it doesnt wake up no matter how many keys i press and it just stays stuck on a black screen. I know that when you put the computer to sleep you hear absolutely no noise however in this case i hear a slight fan noise despite it 'sleeping'. When this happens i always have to use the on/off button to do a reset. What seems to be the issue here??

Whenever I insert a blank DVD there's a long pause and it spits it out again, nearly every time. There's no dialog, no message, no reaction from the OS of any kind.
On the rare occasions when it accepts a disk, everything after that is fine. I can burn DVDs no problem. The DVDs are a variety of different types (all DVD-R), from reliable brands.
I've tried rebooting, changing the settings in System Preferences, quitting all applications except the Finder, but nothing has made any difference.

Does anyone know the maximum recommended operating time for the new iMac. I have run my other Macs on occasion for 48 hours straight. I have often wondered if I am shortening its lifespan with these marathon days.

I have an Intel Imac G5 2.66 gHz 2 core duo running 10.6.3. I am unable to get it shut down or sleep. Choosing either results in the display blacking out, the fans run for about 1 second and then everything come back on as if nothing has happened. I've reset the Pram and Vram, disconnected all USB and Firewire devices, tried it with and without file sharing and Airport operating. A 'hard' shutdown with the power button works fine. I have checked for any firmware updates but mine is fine. This happened once before and clearing out some files from deleted apps cured the problem but it's back now.

I like to use my iMac 24" at odd times and wish to mute the startup chime (or at least make it quieter) so I won't wake up my spouse. Apple Tech support helped me do that when I had 10.5.8 but they deleted several cache files buried deep within the OS. My tech support has expired and I wonder if any of you can help?
