Hello,
If you haven't performed any maintenance on your iMac, then you should read the following:
For applications that freeze or quit unexpectedly like iTunes/iPhoto go here:

A good disk utility to empty caches: http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html
Use Onyx once a week, run the Maintenance and Cleaning scripts and that will help speed your Mac up pronto.
Run Disk Utility (Applications/Utilities) once a week and Repair Disk Permissions:
Launch Disk Utility. Select MacintoshHD in the panel on the left, select FirstAid, then click: Repair Disk Permissions. Quit DU when it's finished and reboot.
*Tip... very important: Run Disk Utility BEFORE and AFTER all software updates. That will save you headaches down the road.
You do not need to limit the number of apps installed but one thing to bear in mind. A Mac needs a minimum of 10% available disk space just to boot and it's all too easy fill up a drive and before you know it, you can't open apps, or they open and freeze up, or you can't install software. A good way to keep an eye on available space: Right or control click the MacintoshHD icon on your Desktop, then click: Get Info. In the Get Info window, click the black arrow next to: General so it faces down. You will see: Capacity and Available ... Best best is to always have 15% free drive space.
Back up your important data every day. If you have a system failure and need to either do an Archive and Install or completely wipe the drive and reinstall your system software, you'll be glad you did.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software.

I hope I didn't inundate you with too much too soon, but just do maintenance, keep your Desktop clutter free, and back up your files daily. Once you get into the habit of doing this, it only takes a few minutes a day.

  • Imac intel won't restart, I get gray screen and spinning wheel then shut off

    My imac intel only restart after running disk utility, otherwise I get a gray screen with apple logo and spinning wheel then after about 2min it shuts off.  this all started after a power outage.  I have tried everything that I have read online to fix this, it seems doing a clean install is last resort. Does anyone have any other options for me?

    Your system profile confirms you are using OS 10.5.8.  Boot up from your OS 10.5.x install dvd.  Use the "repair disk" setting.  If you get the same error, then run Apple Hardware Test from your original system dvd.

  • I have an iMac that won't boot up.  I've read all posts on this subject to no avail.  When power is switched on, it chimes, Apple logo appears, spinning wheel, then loading bar starts to fill.  It gets to about 25% then switches off! Help please!

    iMac that won't boot up!   When power is switched on it chimes, Apple logo appears, then loading bar, then spinning wheel.  Bar seems to load up and gets to around 25%, then reverts to the start again, gets to about 20% on the bar and then switches itself off leaving a black screen.  Tried all the remedies on internet with no avail so would welcome some advice other than binning what is a relatively new computer.  Earliest appointment Apple could offer was Thursday 17th, really useful for a business user _ not impressed,

    You've probably tried this, but will it Safe Boot? Restart holding down the Shift key until you see the grey progress bar. You'll need to input your admin password during bootup. If it will boot you can then try to eject the disk using the various suggestions here that you haven't tried already:

  • HT1379 My iMac is frozen. There is just the spinning wheel.

    My iMacs frozen. It will turn in, and the screen pops up; but there is just the spinning wheel. I can't click in anything. I've tried turning it off and back on, and it didn't work.

    Disconnect all devices from the computer then do the following:
    Boot up from your Snow Leopard Install DVD while holding down the "c" key.
    Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
    Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
    Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
    If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.

  • HT3964 Start my iMac 27 os lion - apple appears then spinning wheel then circle with diagonals  but will not start

    My iMac does not fully start up
    Spinning wheel with circle with line thru on forever

    This screen appears when OS X is damaged and your computer can't start it. As you are using OS X Lion, first check that your hard drive is OK.
    Hold Command and R keys while your computer is starting, and open Disk Utility. Then, select "Macintosh HD" in the sidebar and verify the disk. If it's OK, close Disk Utility and reinstall OS X. If it's damaged, repair the disk

  • My imac won't load properly and gets the spinning wheel for everything!? Help!

    HI everyone,
    hope hope someone will be able to help.
    My imac freezed up the other day for no apparent reason. I couldn't do anything apart from move the mouse. So had to shut dow with the power button.
    When it restarted I was able to log in as usual to the user that I normally use. Yet when I went to click on anything I get the spinning wheel of death! I've rebooted in safe mode but this didn't make a difference. I can't even run disk utility to check if there is an issue with the drive!
    Any help would be greatly appreciated!
    thanks charlotte

    Sounds like maybe the Hard Drive is failing or has failed.
    1. Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.) 
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk.
    If you can not see the Mac OS X volume (Macintosh HD) in Disk Utility while started up form the Install Disc, then you will need to make an appointment at your local Apple Store or AASP and have them help.
    If you have a good backup in place, then you can easily restore the new Hard Drive from backup. If not, then depending on what is wrong, you may or may not be able to recover your user data from a bad Hard Drive.

  • IMac won't start; I only get the spinning wheel

    iMac (probably 3 to 4 years old)------I don't think this is an Intel.
    I have a password to enter upon turning on iMac
    What I did:
    I backed up my files on an external drive.
    I ejected the external drive & unplugged it from the iMac.
    Selected Shut Down. Screen went blue (I think) then did NOT shut down. I waited 10 minutes or so. Still didn't shut down.
    I pressed power button to shut off. Waited a few minutes then turned on. The grey screen with Apple logo and spin wheel appeared and that's as far as I can get.
    I tried turning off and on but never got past the Apple logo/spin wheel.
    I unplugged power, mouse and keyboard, replugged them in. Turned on but still no luck.
    I hope you can help.

    it sounds very much like your hdd has died, however, if it has, at least you have the good fortune to have backed up your system.
    try booting by holding the alt key. if you can get to utilities perhaps you will have a better understanding of what is going on there.
    the reason you cannot get past the spinning wheel is that the mac cannot access the startup volume which is your hdd.
    if this is the case then dont be too disheartened, take this opportunity to consider a ssd for your machine it will give it an especially good new lease of life.

    HI,
    "In the last weeks though when i restart my computer,it just doesnt see my external hardrive. I have to disconnect he fireware port 800 and reconnect and then all ok"
    Try a different USB port.
    Also, go here: iMac Fast Start: The new user's guide to iMac There are links provided that can help you learn how to use your iMac.
    Also, as for the Free Agent external disk, go here to their Support page and check out their Community Forums and Knowledge Base.

  • My imac 5.1 freezes or coloured spinning wheel then shuts down.

    Hi
    My imac 5.i freezes or has a spinning coloured wheel and locks up, or the screen goes white or shuts down on it's own .
    Any help !

    Hello:
    Try resetting the PRAM and SMC.
    If it continues, take it in for service.

  • IMac G4 starts up to gray apple screen progress wheel, then shuts down.

    I was trying to boot to an external drive when this started. I was holding down key combinations (I think at the time it was Option-Command-Del), and the screen went black. Power Off.
    Now, even after resetting PRAM and PMU, among other things, the same process occurs:
    1) I press Power Button.
    2) Chimes.
    3) Gray screen, progress wheel. Little sound inside. Wheel stops.
    4) iMac shuts off by itself.
    When trying Verbose mode, I see it says "CPU Halted" the second before it shuts off.
    Any ideas, masters of mac?

    Try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption.
    It's worth trying the repairs several times with fsck or DU, you never know. But, more then likely you will need a more robust utility, DiskWarrior, to repair that fairly serious error. It costs a few bucks, but if your data is worth saving DW may fix it.
    We always recommend users, here, have at least one backup drive. I have two bootable backups. I have had backups also go bad, so two seems safer to me!
    Cheers!

  • I have an iMac and I keep getting the beachball or spinning wheel coming up It doesn't let me continue until it stops I also have to force quit it.

    I have started it in safe mode and it doesn't help. I have reinstalled it and that doesn't help. I love firefox and don't want to switch. Can anyone help me.

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.

  • Will a new iMac 27 inch Quad i7 with only 4 gig RAM and 1 terabyte HD

    Will this stock computer i7 Quad with the stock RAM and HD run Final Cut Studio 3 full suite effectively for basic HD editing from my new Canon hard drive/SD camcorder or should I immediately upgrade to 8 Gig RAM and 2 Terabytes HD to get the full benefit of this computer. I would like to upgrade them both later but I want 100% performance. I'm only editing 20 to 60 minute segments right now and only a few at a time and only one open at any given time.

    I'm being told that "never" load your workflow into the same hard drive as your operating system. I'm sure that's an exact and professional statement and true, when possible. With this iMac you can't run and external hard drive and download effectively at the same time in order to bypass your internal hard drive because you have only one Firewire connection.USB 2 is supposed to pause and interrupts the flow so it is said to be ineffective for this purpose. I haven't found out yet about the SD card to an external hard drive but if it does I'm still being told that color correction cannot be added because it's in your external hard drive and the only solution is two hard drives in your computer to be able to effectively do all this and that is not an option with this current version of iMac..

  • IMac 2.4GHz w/4 Gig of Ram now running SLOW.

    iMac 2.4GHz w/4 Gig of Ram now running SLOW. Activity Monitor shows all RAM is being used except for 300 MB. How can I tell if I have things running in the background I don't need?

    I know about the Dock showing what applications are open, but when I look at the Activity Monitor, I see numerous things running (maybe 40-50) that don't show in the Dock.
    I've got a 350 Gig HD with 170 Gig available.
