I5 iMac won't complete shut down after installing Lion

When I try to shut down my iMac it gest as far as the white screen with the spinning wheel.  It never completes the shut down.  I always have to force quit it by holding down the power key.  Any suggestions?

I have the same issue was fine after 10.7 install but happend straight after 10.7.1.  I have reset PRAM NVRAM and reset SMC, I have also been to the genious bar where they did an erase and install of lion, it then closed down six times and has now stopped closing down again.  I can't think of any other option i'm sure that it must be something in 10.7.1 so will wait for 10.7.2 with my fingers crossed.  Any other thoughts out there?

  • My Macbook Pro won't shut down after installing Lion.  Anyone have a suggestion to fix this?

    Just installed Lion, and it won't shutdown!
    The only way it'll shut down is if it drains the battery.
    Help!

    Lots of other people are complaining about their Macs taking long times to shutdown. Some solved it by reinstalling Lion from scratch (without using a Time Machine backup and simply copying all their files on to the new install).
    Others discovered old software that is no longer compatible with Lion (I found Mac The Ripper in mine, plus many others on day 1). I uninstalled some apps using App Cleaner (google it, it's free and it's awesome).
    I was having a hard time shutting down my macbook pro, now it's back to normal.
    Try finding applications that are not compatible with Lion. Their icons should be greyed out and with a diagonal line crossing it. Make sure you erase these applications and library related files, which is very simple if you use App Cleaner. And make sure you look into sub-folders inside the Applications folder, as I missed a couple because they were not immediately visible.
    Hope it helps. If it does, let us know.

    After having shut down after installing updates, when I restarted and tried to open a word doc, it started opening ALL the word docs and the only way I could stop it was by"force quit"  . This is REALLY annoying!!

    May be it is the Resume feature.
    System Preference > General > Number of recent items
    Uncheck the box next to      "Restore windows when quitting and re-opening apps".
    Best.

  • My new imac won't operate youtube even after installing the latest flash

    my new imac won't operate youtube even after installing the latest flash

    Problem solved!
    I had downloaded and then installed Flash, and restarted. 
    The problem?  I was expecting Youtube to work as on my old PC, where you get a little pop-up menu at the bottom of the TV screen to play. pause etc.  That won't happen on a Mac until  you click on the oblong that says Flash in the middle - I didn't know that!
    Hooray!

  • My ipod touch completely shut down after i tried to update the software. It won't respond at all. Any advice?

    Hi, I was updating my apple software and my ipod touch completely shut down. I got an error message that my ipod touch could not be restored. what the ????
    please help. it wont start at all, no power. itunes doesn't even recognize it anymore.

    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."

  • IBook won't completely shut down

    I have a 1.2ghz iBook with 1.25 gig ram running 10.4.1.1 that will not totally shut down after you tell it to. The finder will quit and the screen will turn blue, but that is all that happens. To make it shut down, you have to hold the start button for 5 seconds, then it will turn off. I've run disk utility, cocktail and onyx, but still nothing. Anyone have any ideas?

    If you have not tried the "Resetting PowerBook and iBook Power Management Unit (PMU)"
    procedure outlined here: http://docs.info.apple.com/article.html?artnum=14449 to see if
    the odd behavior can be checked and fixed, I suggest you could try the one they recommend
    for your computer on that site. Also, note there are a few other things to try first, shown there.

  • Slow down after installing Lion OS

    My Macbook pro later than 2009 model slowed down after installing the new OS Lion
    any suggestions to speed it up

    First suggestion ,there have been a number of identical user questions like yours, in the Lion Community. If you want to talk to other MacBook Pro owners, try the forum they have.
    http://www.apple.com/support/macbookpro
    What you do not need is some gizmo to "speed up" or clean caches etc.
    Maybe you need to make more room on your hard drive, or add more RAM.
    For now, hold down Command-R and run Disk Utility to check the health of your system drive (Lion Recovery Mode)

  • IMac keep shutting down after installing OSX lion

    Hi,
    I have a mid 2010 27 inch i5 machine and after I had installed OSX Lion last month the machine randomly shut itself down while I'm using it.  At first I thought it was because of a software problem with Final Cut Pro X, since I installed that at the same time and it would shut down while I was using it.  Then it start to shut down while I'm just browsing the net.  Restarting is not a problem but a pain to loose unsafe data when it crashes.
    Does anybody else have this problem?  Again the machine was working fine before OSX Lion so I don't think it's a hardware issue.  On average it would shutdown once or twice per usage day sometime a few minutes after turning on the machine, still cool, and sometime after a while, not excessively hot.
    Appreciate any help and thank you in advance!

  • Problems shutting down after installing 10.5.3 update?

    Has anyone had any problems shutting down there IMac's after installing 10.5.3 update? I've tried shutting down twice and the image that appears when shutting down seems to go in an endless loop an doesn't shut down.

    Can you restart from the menu and hold the shift key down, until the Mac
    boots in a SafeBoot login screen; then choose Disk Utility (shortcut under
    GO in Finder window, to Utilities folder) and run 'repair disk permissions'
    then restart the computer normally...(?)
    You may also have to consider starting the computer from the OS X
    installer disc and choose from an option menu there (not to install)
    and choose to use Disk Utility from the booted installer disc, to run
    'repair disk' from there? You could also run 'repair disk permissions'
    while booted from that installer disc, but maybe you'd still have to
    repair those from the running system for best effect once it is back
    running from the hard drive's system.
    Some minor issues can happen after an update, usually just repairing
    disk permissions before installing the update, and/or running up in
    SafeBoot, can help. There are other things to try and do, if these don't
    help that much. The state of the system prior to an update is important;
    since an update can't fix anything otherwise non-related to an update.
    Maintenance issues aside, after you repair disk permissions, safeboot,
    and restart, if there still is an issue, you could try to download the Combo
    OSX 10.5.3 update file and install it over your system; and then repair
    disk permissions again after it finally restarts normally.
    Was the 10.5.3 update a smaller (delta) file or was it the Combo (large) file?
    Good luck & happy computing!

  • TS3824 My iMac won't wake from sleep after installing the most recent OS update.

    I'm having trouble with my iMac, the screen won't wake up after it goes to sleep. The one time it did the screen was all fuzzy and pink. This has only happened in the last few hours after installing the latest OS X Lion update. Is this normal? Can someone help?

    Hello, not normal.
    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 problem 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.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...
    /private/var/run/StartupItems
    /Library/StartupItems
    /System/Library/StartupItems
    /System/Library/LaunchDaemons
    /Library/LaunchDaemons
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there to Repair the Disk, then Permissions.
    Re-install if that doesn't work.

  • Adobe CS6 Apps Shuts Down After Installing Creative Cloud.

    I can't start my Photoshop, Illustrator or InDesign CS6 anymore, it just shuts down as soon as it's done loading, without any errors. Only Bridge CS6 will start.
    I tried launching with Ctrl+Alt and Ctrl+Alt+Shift but it did not work.
    Then I tried uninstalling it (With all the preferences as well), and install it again, that did nothing - still the same issue.
    I updated windows and my gfx drivers (GeForece 332.21 - NVS4200M) after the issue started.
    I tried both the 32bit and the 64bit version.
    I have manually removed the preferences file.
    I have disabled the firewall and my AV.
    I have logged out and back in of the Creative Suite Utility.
    My hosts file is not blocking any sites.
    I am running Windows 7 Enterprise 64 bit.
    I tried to open a issue on superuser but that did not help, nobody has awnsered it yet.

    Nicoar do you receive any specific error messages?  I would recommend starting with the steps listed in Error "Failed to Install" Creative Cloud Desktop application - http://helpx.adobe.com/creative-cloud/kb/failed-install-creative-cloud-desktop.html.

  • 8.1 can't shut down after installing itunes

    I recently reformatted and did a clean install of window's 8.1
    I have done all updates, both windows and drivers and the machine is very smooth and stable.
    After installing iTunes the computer will no longer shut down, it displays the logging off / shutting down screen but then just reboots.
    I have attempted numerous resolutions to no avail, i.e. disabled NIC as bootable device, disabled the hybrid boot feature & flashed and tweaked some BIOS settings.
    The computer will not even shut down when I give the command "shutdown /s /t 0"
    I only had Windows Office and iTunes installed on the computer and suspecting that iTunes may be the culprit, I uninstalled it and now the computer shuts down without any issue.
    I have since read several threads about iTunes and shutdown/restart issues with 64 bit versions of Windows although I have not found anyone else with my exact issue.
    Is anyone aware of a resolution for this?
    For now I will need to install iTunes so I can sync my phone and then uninstall so I can shut down!

    Fingers crossed there will be an update for this, I was lucky that my install so was new that there weren't very many things that could have caused it because I don't think it would have ever occurred to me that iTunes was the issue.
    I literally tried every other possibility before waking up in the middle of the night and realizing that the problem started right after I installed iTunes.
    I have had issues with Apple software in the past where I attempt to disable it from launching automatically when I boot the computer and it will simply create another entry for itself in the startup list.
    If I disable that one it makes another, and another and another.... It's like the freaking Apple hydra.
    The want me to know how much I need them! lol

  • Kernal panic preventing shut down after Mountain Lion upgrade

    Following upgrade to Mountain Lion, kernal panics are stopping shut down of my Mac from the apple menu. I have a late-2009 Mac Mini. OS X closes as normal but then restarts with message "Your computer restarted because of a problem". I have performed disk verfication, repaired permissions, reset VRAM and SMC. Booting from original hardware disc allows a normal shut down, so I suspect this is software related (probably Mountain Lion?). Kernal panic report from Console is below.
    Reading this https://discussions.apple.com/thread/4135480?start=30&tstart=0 suggests problems with nvidia cards and Mountain Lion. My Mac Mini has the original nvidia card it shipped with (9600M) and if I disconnect the display just before shut down it (usually) seems to shut down normally so might be display related?
    Other than the problem with shutting down everything is working normally. First instance of this problem was immediately after installing Mountain Lion. I am currently considering a full-reinstall of Mountain Lion from the recovery partition and using Time Machine to retrieve my settings etc, although I am concerned this will not work if it is a genuine bug.
    Any assistance or solutions gratefully received!

    Hello hotdavesweet,
    It sounds like you have exactly the same problem as I have - nothing connected except the TV, permissions repaired, PRAM reset, etc.
    Are you using Mountain Lion?? I had to downgrade to Lion to solve it. Unfortunately, a very similar problem occurs with the latest version of Lion (10.7.5). I'm sure that something with the latest updates is causing problems on certain Macs. I've filed a bug report with Apple so it may help if you do the same.
    It could be a problem with using Samsung LCD TVs as monitors. Or maybe a graphics card issue - the user in this discussion: https://discussions.apple.com/thread/4316892?start=15&tstart=0 noted that a similar problem on a 2009 Mac Pro was caused by their (nvidia) graphics card driver.
    Either way, I think it is something that Apple should address, even if it is only affecting a few users. Apple's mantra used to be that everything just works, but now I cannot upgrade to Mountain Lion with my setup (despite my Mac being easily capable of running it) and nor can I upgrade to Lion 10.7.5. It doesn't work as it should.

  • Acrobat 9 Pro shutting down after install

    I just purchased Acrobat 9 Pro upgrade. The install goes smoothly. However, when I go to open up the program, it opens and then shuts down. I have tried reinstalling after unstalling and still have the same problems. Does anyone have any suggestions? I need to get to open several pdfs and I can't.
    Thank you!

    Do a search for others with this problem. It is being reported a lot right now and seems to be related to a MS issue. Of course, Microsoft says the vendors need to ensure the compatibility. Bill
