After Mountain Lion install some software stopped working

Besides some software not working Mission control will not work. I have no way to switch between desktops. I am thinking about doing a reformat and starting over.

Then you need to purchase a copy of Snow Leopard. You cannot install Leopard, Lion, or Mountain Lion without first erasing the hard drive if you don't have Snow Leopard installed. You cannot reinstall Snow Leopard without a Snow Leopard DVD.
Upgrading to Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
If you need to purchase Snow Leopard you can still purchase a copy from Apple's online store's telesales agents.[1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775.] Ask for a Sales Representative.
Third-party sources for Snow Leopard are:
Snow Leopard from Amazon.com
Snow Leopard from eBay
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.
If you need to purchase Lion call 1-800-692-7753 or 1-800-676-2775. Ask for a Sales Representative. They will check your Apple ID, and email you a code and instructions.  The cost is $29.99 (as it was before) plus tax.  It's a download.
Be sure your computer meets the minimum requirements:
Apple - OS X Mountain Lion - Read the technical specifications.
Macs that can be upgraded to OS X Mountain Lion
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)

  • After Mountain Lion install, internet videos stop playing back after only a few seconds. Multiple browsers are affected.

    After I installed Mountain Lion, videos streamed from the internet will stop playback after a few seconds of play. Multiple browsers are being affected.

    I have this same problem, and I did a clean installation.
    Hardware:
    2009 MacBoook Pro 17" 3.06 C2D; 4 GB RAM, 256 Apple SSD
    While loading the browser is quick starting up, I notice a delay to open any website, like it's preloading the entire page versus just loading.  Safari seems like it's a bit sluggish overall with loading web pages.
    Did a internet speed test and my U/D rates are the same after the upgrade.

  • After Mountain Lion download, FaceTime is not working anymore. Any ideas?

    After Mountain Lion download, FaceTime is not working anymore. Any ideas?

    I have reinstalled mountain Lion again . This time, Facetime works when somebody calls me, and I can do calls from my Mac again. But the problem was still that I was not able to call my iPad, what I was able to do with Lion (I had one Apple-ID and two call adresses). The solution was this time to generate a second Apple-ID from the Facetime in my Mac (this doesn't affect your main Apple-ID, it's only used for Facetime). Now, it works!  ;-)

  • Problem with mail after mountain lion install

    Mail has become sluggish to locking up after Mountain Lion install.  I get the color wheel each time I start typing in an address to send an email.  I also get the wheel when i am typing an address or name in any web page in Safari.  Is this a Mail Problem or an Address Book problem?

    It sounds like your computer needs to be cleaned up. Have your repaired permissions or cleared caches since you got the computer. Often times when upgrading operating systems permissions get screwed up and it causes issues.  Go to disk utility in your "other" folder in applications.  Select disk utility, then on the left hand side choose Mac HD then click REPAIR permissions in the center section. Wait for it to finish, restart your computer, then test.

  • Trackpad issues after mountain lion install

    Since my Mountain Lion install, the trackpad on my 15" MBP will track, but won't select anything.  Hot corners aren't working, the dock won't appear, etc.  Anyone have any suggestions?

    Got similar issues, no notifications and no switching between full screen apps (4fingerswipe). Some swipe features work, no secondary click in bottsom corners...Trackpad operational under Mountain Lion a total nuisance compared to Snow Leopard...PLease Apple, show some respect again to your faithfull customers and show some response!

  • After Mountain Lion install, my iMac powers off instead of just going to sleep. Help? Thanks.

    After I installed Mountain Lion on my 2009 iMac, it will power off after I don't use it a while. It used to just go to sleep, I'd shake the mouse, and it would come back up. Now it powers off and I have to power it back up every time. 
    My Macbook has NOT had this problem since Mountain Lion install. It is fine.

    Do these resets to clear errant commands:
    SMC RESET
    http://support.apple.com/kb/HT3964
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    The 5 second timing is important to a successful reset.
    PRAM RESET
    Zap the PRAM
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Thunderbolt is not working after Mountain Lion installed

    I'm putting this discussion again because the problem didn't solve like I thought !
    As you can see from the title that I have a problem already after I installed the new OS X Mountain Lion. I got my thunderbolt to Hdmi adabtor connected to an LCD TV and it was working great with snow lepord. But after the I installed Mountain Lion. it won't even recognize that there is something connected and I don't see the options in my System Prefrences> Diplays like before.
    I already run software update and it's all up to date and also done a PRAM reset and nothing changed.
    It only ok for a couple of min. if I restarted it and without the sound working from the LCD TV.
    Please I need help here.

    Well I would have hit repair. This might be stemming from a deeper issue with the installation. I've never seen that dialogue box before, and if ignoring it and booting normally worked for you then I say you did the right thing.
    however
    I would, go to disk utility and then select your boot drive and verify and repair disks and permissions.
    if anything else WEIRD should occur, you may want to go to the recovery partition of ML (cmd+R while hearing the boot chime) and reinstalling ML. That dialogue box you mentioned is strange and should be noted. A reinstall will probably fix whatever issue comes up.

  • Messages won't work with iMessage after Mountain Lion install

    I previously had Messages Beta installed on both my Macbook and iMac and they worked great.  Now I upgraded to Mountain Lion and Messages works fine on my iMac, but not on my Macbook.  It defaults to Bonjour and when I enter the Apple ID info I get a message "Your Apple ID "[email protected]" can't be used to set up iMessage at this time.", and it says to contact customer support.  What is causing this and does anyone know how to fix it?

    HI,
    I must admit to not having two computers to try this on.
    The one I do have is an iMac and updated from Lion to Mountain Lion with Messages Beta still active in the Lion build and I did not have any problems.
    I can see that the iMessages servers could be getting confused as you are trying to use the same Apple ID on the MacBook as is in use on the iMac.
    Try going to the preferences in Messages on the iMac and Disabling the iMessage Account whilst you set up the nmame in a MacBook
