Help! Mac is super slow after installing mountain lion

Ever since I installed Mountain lion on my new imac everything seems to be working really slowly. iphoto takes about 5 minutes to start and once it has started up it is really slow. Same thing happens with itunes. I have repaired disk permisions many times and also have run my Mac Keeper program as well.None of these things seem to help and it seems to be getting worse. Has anybody else have this trouble? Any ideas would really be appreciated. Thanks

  • My wifi is very slow after installing mountain lion on my Mac book pro

    My wifi is very very slow after installing mountain lion on my MacBook pro.
    What can I do?

    Ha  ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
    BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.

  • HT1338 Why is my MacBook Pro running so slow after installing Mountain Lion 10.8.

    Why is my MacBook Pro running so slow after installing Mountain Lion 10.8. I have restarted, created more free space on my hard drive and run disk utilities. Simple operations result 20 seconds or more of the spinning wheel. Some are so slow that the operation does not happen at all. Itunes music cuts out during operations.

    Check out this article by Thomas Reed for help http://www.reedcorner.net/understanding-upgrade-nightmares/. Also, make sure all apps are compatible with Mountain Lion using www.roaringapps.com. Do you have any antivirus installed? Make sure all apps are updated as well.

  • My macbook pro is very slow after installing mountain lion

    my macbook pro is very slow after installing mountain lion?  Is anyone else having this issue?

    If you don't use an SSD and bump your RAM up to 8 Gb's you may experience slow speeds, but I noticed slow speeds with your general configuration in SL.
    one thing you should consider right now is, Spotlight is Reindexing your hard drive, that takes time and resources, (resources which you don't necessarily have to spare).
    If you continue feeling like your performance is slow, you have a few options with this computer (I have the same one).
    the express card slot can house a wintec SSD drive. That little door on the side of your machine is pure gold for a really quick solution for speeding up your machine. I have one in mine right now i'm using as a scratch disk for CS6 but I used to boot from it, and the speed boost was out of this world.
    You could take out the internal HDD and put in a new SSD (I have a Vertex 4 from OCZ) it is completely over kill but my experience is pretty fast and I keep up with the later MBP models colleagues have.
    There are some other options for you like taking out the optical drive (however I don't know if I'm supposed to talk about that here). Google Data Doubler.
    You need to also set it to always use the 9600 chipset, this will increase performance a lot too. to do this go to system preferences>energy saver>Better Performance. This switches the video card to the better one and makes a world of difference.
    Lastly, your RAM. after an EFI Firmware update, our computer support up to 8GBs of RAM. Do it!

  • My Mac Pro is hanging after installing Mountain Lion

    My Mac Pro is hanging and it started not long after I installed Mountain Lion. It seems to be related to Contacts in that it is constantly trying to sync with iCloud. It becomes unresponsive and when I force quit, other apps start going down. Eventually Mail hangs and I have to hit the power button and force a restart of the Mac Pro. It also brings down my DSL connection which runs through an Airport Extreme. Has anybody had similar experiences? Contrary to what it might say in my profile, I'm running a 2.8 Ghz Quad Core Mac Pro and 10.8.2.

    Welcome. If you search for "Mountain Lion freeze" you will see you are NOT alone. But as far as I know there is no solution.

  • Safari runs slow after installing mountain lion

    Safari is running very slowly since I installed Mountain Lion.  Any suggestions about why this is happening or how to improve the speed?

    I ordered something from a website I haven't used before, and it was very slow, but I don't know if it's that website or safari.  Safari is the only browser I use.

  • Mac won't start after installing Mountain Lion

    After installing Moutian Lion (from 10.6.x) overnight I returned home yesterday evening and wasn't able to start up the mac.
    I get the white screen of death and a little spinning wheel and then the mac shuts down.
    I tried rebooting in recovery mode and did a "repair disk".....it said that it couldnt repair the disk.
    I tried the "reinstall the OS X" option but the two drives it showed me are both locked so I couldnt do that either!
    I didnt have time to do anything else.......what do I need to do now? WHat are the next steps? Sledgehammer? Dynamite?
    Thank you
    HMHB

    Thanks Arthur,
    Point 1 sounds scary and expensive!
    thanks for the link I will try some of these when I get home and will report back.

  • Mac Book Pro i7 late 2011 Running Slow after installing Mountain Lion

    Hi All,
    Is anyone else experiencing the same issues, since I have updated to Mountain Lion last week my mac is now running alot slower than before on startup, closing down and when opening and shutting programs / apps.
    Would it pay me to upgrade to 8GB ram?
    Thanks

  • Why is my MacBook Pro very slow after installing Mountain Lion 10.8.5. - Solutions?

    Hello, hello
    After waiting quite a while - I paid the relatively small amount, and got myselves a new OS.
    But I am very disappointed of the speed - I see that this also was a problem with OS Lion?
    Please assist me. Perhaps others have this problem as well?
    Some info:
    - 2,66 GHz Intel Core i7 processor
    - 4 GB 1067 MHz DDR3
    Also
    - Sometimes I run the Parallels Desktop 6 and 9 software, does this affect specs of the new OS?
    Hope to hear from you guys.
    Sincerely,
    Harald

    With only 4GB of RAM, how much do you have devoted to the virtual machine running under Parallels? Even if it's a small amount, it's going to make page outs and swaps used very high. From my perspective, 8GB of RAM is the 'sweet spot' for running Mountain Lion.
    I'm assuming that you've a 15" mid-2010 MacBook Pro? If so, you can speed things up by installing the maximum 8GB of RAM. Go RAM shopping at Crucial or OWC.
    Other than upgrading your RAM, the only thing that you can do to speed up your machine is to install a SSD. You can also check the SSDs at Crucial and OWC and decide if one is right for you.

  • Slow after installing mountain lion

    About month ago upgraded, gray screen, endless spinning wheels every color & shape, safe mode over & over, re-installed ML several times & it would freeze for DAYS in the process, force quit, repeat.  So now for whatever reason, I got the computer on but it's very, ver, ver (did I say very?) slow.  What do I do?

    I ordered something from a website I haven't used before, and it was very slow, but I don't know if it's that website or safari.  Safari is the only browser I use.

  • Mac Pro intermediate black screen at boot after installing mountain lion

    I have a 2008 Mac Pro tower, but since installing Mountain Lion I now get a random black screen at boot. Unplugging the apple cinema 20' power supply for 15 minutes seems to clear the fault. Have had no such problems with other OS until Mountain Lion, seems OK when booting to Snow Lepoard on my other drive?
    Anyone have the same fault?

    Thanks for trying the help! I tried every version of start up, but with no screen it was no good..
    Finally solved the problem, it was the ATI HD 2600 XT graphics card that was dying a very slow death.
    Replaced it this morning with a GT120 Nvidia.
    Anyone with this card should Google it, as apple did a big recall on these..

  • Mac pro won't wake up after installing Mountain Lion

    After installing Mountain Lion in my Mac Pro it won't wake up after long periods of sleep. I have tried unplugging it for 15 seconds and plugging it back in and starting it back up. No help. I've reset the Pram with no change.
    Chuck

    Two calls into tech support, but I think they may have helped me fix this.
    CHECK:
    \Library\LaunchAgents
    \Library\LaunchDaemons
    \Library\StartupItems
    remove any third party software and set aside.  (they told me I could keep some adobe, microsoft and HP items)
    THEN CHECK:
    System Preferences --> Users + Groups -->Login Items
    remove any third party stuff from in there.
    I'll know tomorrow morning if this REALLY works, but it dfefinitely allowed my computer to sleep and wakeup over a short period of time.

  • Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

    Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate... (the same happens with the other iWork-Apps!)
    Looking forward to hearing from somebody with a littlemore expertise than me, Chris

    you can remove preferences files by navigating to the Preferences folder for your user as follows:
    0) Quit ALL iWork apps (Keynote, Pages and Numbers)
    1) from the Finder select the menu item "Go > Go To Folder…".  This will bring up a dialog:
    2) enter the path "~/Library/Preferences" (no double quotes)
    3) find the files:
    com.apple.iWork.Keynote.plist
    com.apple.iWork.Numbers.plist
    com.apple.iWork.Pages.plist
    and move these to the trash.  I would NOT empty until later.
    4) restart Numbers
