IMac lags on shutdown

my imac has been getting the little pin wheel on shut down. It used to shut down automatically.
Cab someone pleased help. Is there a solution? My iMac is 2.4 GHz

it has 29.87 GB free out of a 250 GB drive, also this has started happening today (copied from my macrumors thread on the same topic)
"now it is giving processor usage which isn't normal for me on what i do on a regular basis. i usually have about 85-95% idle, now its from 58%-76. i tried to shut down and restart my mac(still lagging on shutdown) but when i turned it back on it still had the same processor usage when i checked again. someone please help, im getting a little worried(being that when i switched to mac, the paranoia from having a windows machine and worrying about problems it might have stuck with me)"
sorry if this is posted twice, i just typed it up and it didnt show up on the thread, EDIT: i just realized it takes a minute or so to show up in the thread :P, ive got to read a bit more next time

  • Imac does not shutdown

    My IMac does not shutdown through the normal operating procedures.  I have to press the reset/shutdown button in the back.  Plus it constantly freezes up.  I have over 100GB of free space.  Total capacity is approx 500GB

    Open up Disk Utility, and select Macintosh HD on the left, then click on "Verify Disk" in the bottom right. See if it checks out or not.

  • After security update 2011-005, iMac fails to shutdown

    Hi All,
    I just upgraded my work computer running OS X 10.6.8 to latest security patch (2011-005), and after that my iMac can't shutdown anymore.
    The process that is hanging is Apache Tomcat 6. Exactly org.apache.catalina.stratup.Bootstrap
    We looked into System diagnostics and there is nothing there!
    It looks to me that it has to do with permissions and dependencies, but I have no clue where to look!
    PLEASE HELP!!!
    Many thanks,
    Sava

    Don't remove any screws to do an SMC reset:
    Resetting the SMC on portables with a battery you should not remove on your own
    Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • IMac hangs on shutdown

    Hi there, I have just installed iLife 08 and iWork 08 this afternoon and since then my iMac won't shutdown properly. I shutdown as normal, but the machien hangs with the pale blue screen before shutting down. I have to power off manually. I have never had to do this before. Also, when I power up now, my bluetooth mouse and keyboard do not rspond until I switch off and switch back on the keyboard - this then unfreezes them. How wierd! Hope you guys can help!

    Launch "activity monitor" by typing in "act" in spotlight (and then selecting the program in spotlight) to see what is running. Some things are supposed to be running but some things running could prevent a shutdown because the program causing the problem needs to finish its process before letting the computer shut down.

  • Since Mavericks Upgrade iMac won't shutdown with network cable plugged in

    Since Upgrading to Mavericks my iMac won't shutdown - just stays on grey timer screen.
    I tried multiple fixes from forum suggestions.
    If I unplug the network cable it seems to shutdown fine.
    How can I fix this issue?

    I am working with a T42 (old computer) and it will not boot into Windows with network cable plugged in. It hangs just after the Windows splash screen. Unplug the cable turn off and back on and it works fine.

  • Video AirPlay From Yosemite iMac Lag

    When I AirPlay a full screen video to the Apple TV there is a small amount of lag / gitter.
    I currently have the 3rd Generation Apple TV, updated.
    I am also using AirPlay on an iMac with Retina 5K display, OS X Yosemite (10.10.2)
    I use an E4200 Cisco router with the latest firmware.
    iStrumbler result:
    S/N 71 db, Signal -24 dBm, Noise -95 dBm, Channel 157 (I'm only one using this channel in the area), Frequency 5785 MHz.
    I have verified both Apple TV and iMac connected directly to my router with same results.
    I have been using VLC as my video player.
    The only thing that has worked for me was using Beamer  http://beamer-app.com
    If I use Beamer there is no lag or bitter, perfect video!
    I have posted about this similar issue in the Apple TV community and was suggested trying another router, so this morning I purchased the Apple AirPort Express and experienced the same lag/gitter results.
    Any help or suggestions would be appreciated, I rather not purchase additional software (beamer), to resolve this issue.

    Thanks @vazandrew for quick response!
    I set the Apple TV and iMac both connected directly to my router with the same results.
    I have also used istumbler and Apple's Wireless Diagnostics provided with OS X.  My signal strength and noise are all strong and normal.
    I also moved my wireless router to a new location just to be sure.
    I'm using VLC to play the video, maybe there is another better player?  The video is running perfectly on the iMac just gitters on Apple TV display, it almost becomes unnoticeable after watching for a bit.

  • Illustrator CS6 (iMac) lagging/saving time finally improved.

    I upgrade from a PC with CS3 to a late 2012 iMac 27" with CS6:
    Processor  3.2 GHz Intel Core i5
    NVIDIA GeForce GTX 680MX 2048 MB
    and have had the lag problems that others have experienced, so was very disappointed with CS6 and my new iMac
    I upgraded to 24gb RAM and did not see much of a difference.
    What has helped.....
    1.  First I have changed the resolution to 2048 x 1152 which has reduced the lagging effect significantly.
    2.  Turn off some options in 'Smart Guides' to help smooth the work flow - less flashing lines and snapping.  This option will be down to user needs though but are worth checking.
    3.  When initially doing a "save as" I have unchecked all options.  Saving takes 1-2 secs rather than 5-10. I use 'ForeverSave 2' for 5-10 minute incremental backups so that helps significantly with workflow.
    Hope this helps.

    Sounds like you need to take it back to whomever serviced it 2 months ago and have them honor the warranty on there repair work.

  • My Book Firewire External Causing iMac to not shutdown

    I have several external devices connected to my iMac.
    1. My Book Firewire External HD
    2. My Book USB External HD
    3. USB Hub for mouse, keyboard, USB connection for M-Audio keyboard
    4. Presonus 1394 Firewire Audio Interface
    My iMac does not want to shutdown all of a sudden and I have traced it down to trouble with the My Book Firewire External HD. For some reason, when I Shut Down the iMac, when it does shut down, the My Book remains running even with the iMac off. I have to unplug the My Book to turn it off. Any ideas on why the My Book is causing trouble with my iMac and why it will not dismount when I try to dismount it via Finder?

    The software I was referring to is the Button Manager software which now that I look at it may not have anything to do with the auto power down nor have I even tried it. Just thought I would through out some ideas.

  • IMac - LAGS, especially in Safari! Tried everything please help!

    Hey everyone!
    I have a desktop iMac and in the last few months it has slowed WAY down and its doing my head in!
    I bought it 2 and a half years ago and never had these problems with it. It has 4gb of RAM, 500 gb hard drive and i updated to Lion, which is possibly when it started going wrong!
    ISSUES:
    -Safari majorly lags, especially with YouTube and other online videos, usually gets to about 30 second in then the video stops and lags so badly it freezes the entire machine, i have to force quit Safari!
    -simple things such as searching for a file with spotlight has become such a drag. i type in for example 'work invoice' and it takes roughly about 20 seconds so show anything, it used to show it in about 0.000001 seconds lol!
    -pretty much everything is much slower now but the main issue is definitely Safari!
    WHAT IVE TRIED:
    -ive taken it to my local apple repair shop and they found NOTHING wrong, nothing at all, they had the thing for 3 days and found nothing! they ran so many tests and nothing was wrong with the machines hardware, which is annoying i was hoping it would find something!
    -ive repaired all the permissions, reset safari several times, transferred about 200gb worth of stuff to external and still no luck
    -removed several start up programs and background programs, still nothing, emptied the cache folder like advised by apple over the phone, NOTHING
    Im literally stumped i cannot think of anything else that i can do so im hoping all you Apple experts out there have a simple fix for me because its driving me nuts lol!
    PLEASE HELP ME, i love my Mac and i want it back to the way it should be!!!!!!!
    Thanks a lot

  • Intel Imac freezes on shutdown

    Hi,
    I'm a long time windows user, but I've only had this mac for about 2 weeks so everything is just about new to me. The first week's been no problem but out of the blue during this 2nd weekend my imac has started to freeze on shutdown. I hit shut down, the blue screen comes up, the spinning thing spins and then when the machine should shut down the spinning thing stops. It's completely frozen. I've let it sit like this for up to 45 minutes and it just doesn't work its way out so I have to hold the power button til the machine turns off. I've installed the latest updates and I've ran the disk utility in the utilities folder, but the problem persists.
    Like I said before, this is a new computer and I haven't done too much to it. It's connected to a canon pixma mp150 printer via USB, an HP deskjet 8750 printer via a netgear wireless router, a wacom intuos 2 via USB and my ipod via USB. All that I have installed is the camino web browser, open office and x11, AIM, divx, adobe photoshop cs3 and adobe illustrator cs3. That's all the information I have.
    I tried looking up this problem on google and at the apple website but I can't seem to find anything that matches.
    If you have any ideas what the problem is, I'd love to hear it! I really don't want to have to return this computer and face high restocking fees!
    Thanks!!!

    Hi ChiaCheese,
    one way to solve your problem might be to create a new account into which you copy everything from your old account. This solved my problem with FileVault:
    http://docs.info.apple.com/article.html?artnum=305454
    If that's too heavy, have you checked: Finder/Go/Utilities/Disk Utility.app, run the permissions.
    You can also run the startup from the CD and check the hard drive.
    This page gives good information about what you can do with Mac OS problems:

  • My iMac doesn't shutdown (except in a Bootcamp Partition like XP)

    Hola amigos, el problema es el siguiente, hay muchas veces que intento apagar mi ordenador teniendo alguna que otra aplicación abierta, y se queda la pantalla azul, con la ruletita gris durante un tiempo indefinido, y la única forma de apagarlo es apagandolo del botón dejandolo pulsado durante unos segundos... Esto no pasa cuando cierro todas las aplicaciones a mano, y después apago, o cuando apago desde una partición de Bootcamp (Windows XP)
    A qué puede ser debido ?, antes no me pasaba.
    HI Friends!, here is my problem: sometimes, when i try to shutdown my iMac with some applications open, it stucks on the "Blue" Screen with the grey roulette for an infinite time... It doesn't go down, even it goes to the screensaver mode, and doesn't shutdown...
    This doesn't happen if I manually close all aplications before shut it down, or if I try to shutdown in a Bootcamp partition (Windows XP for example), in the two case, the iMac shut down well :S
    Why does this happen ?
    Thankss and sorry for my bad english -.-

    There are a couple things I can think of. First of all, are you using FileVault? This can cause a shutdown hang if it is enabled on your user account (personal experience). Try disabling filevault via the Security preference pane.
    Another is to repair disk permissions. Open Disk Utility and click on your boot volume, then go to the First Aid tab and click "repair disk permissions". The third thing you can try is repairing the disk itself. Using your OS X install CD/DVD, start up and hold the C key until you see the installer. Click "Installer" then Disk Utility, then click your boot volume and then "Repair Disk" on the first aid tab.

  • 10.4.11 imac freezing during shutdown

    Hi, discovered my mother has been turning her imac off at the wall every night because when she tries to shutdown it freezes. It freezes at the point when the circular lines are spinning. Any suggestions?

    Hi Alexis, and a warm welcome to the forums!
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for action in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
    Reboot, test again.

  • IMac refusing to shutdown?

    Whenever I try to shut down my iMac (roughly %90 of shutdowns) the computer does the standard thing where it removes the dock, all desktop folders and icons from the screen, and it LOOKS as though it's going to go into the shutdown screen but it simply.. Doesn't do anything. I've had to do a few hard shutdowns which ****** me off because I can promise you I didn't pay the amount for this computer that I did for this to be happening.
    I'm running a late 2013 27in iMac w/a 3.5 GHz Intel Core i7, 8 GB of 1600 MHz DDR3 RAM, with a 3 TB Fusion Drive.
    This started happening ONLY after the Yosemite update (10.1.1). I was able to simply push the shutdown command keys again when I had Mavericks, and it proceeded to shut down as normal, but I would have to push it twice sometimes.
    Now I can't even shut it down at all. In all honesty, I'm typing from this current state of pseudo-shutdown to avoid having to do another hard shutdown. I can literally do anything except view my finder window, but I can open all other applications.
    Does anyone have any solutions for this?

    You likely installed something on it that is causing the problem. Please post an EtreCheck report of  your system and we can look for obvious issues.
