When i purchase os x mountain lion from the app store and install it will i keep all of my files and apps on my hard drive

If i purchase mountain lion will it wipe my hard drive or will i keep all of my files and applications

Simply connect an external hard drive to it. Format it if it's not labeled as made for Mac using Disk Utility.
I'd recommend backing it up using Time Machine. Your Macbook should ask you if you want this drive to be used for Time Machine....you do.
Once the backup is done you can, later on, use the backup drive to migrate everything to your new iMac.

  • Unable to download Mountain Lion from the App store

    Hi, when I try to download Mountain Lion from the app store I get the message, " The product distribution file could not be verified ... " Obviously I'm doing something really stupid. Advice welcome!
    Thanks

    A belated thanks for your help. I'd never have solved it otherwise. Maybe Apple could change the automatic reply that I got initially ("The product distribution file could not be verified ....") othewise they risk loosing customers.
    Thanks again.

  • I'm now running OSX v. 10.6.8.  I purchased OSX Mountain Lion from the app store

    I'm now running OSX v. 10.6.8.  I purchased OSX Mountain Lion from the app store & after about 40 minutes of "downloading" (started 40 or so minutes ago) my iMac restarted & I signed in.  But OSX 10.6.8 is still there & the image of OSX Mountain Lion is in my dock with the caption "OSX Mountain Lion -- Paused" !!!  ...Now ANOTHER 20 minutes have passed & no change nor other prompts nor info have come up!!  WHAT'S GOING ON???  PLEASE HELP!!! ~~~THANK YOU!!!

    THANKS SO VERY MUCH, mende1, for so quickly responding to my plea for HELP!!
    I had never turned my iMac off so I still don't understand why the download paused, & when I looked in my Applications folder there was no Mountain Lion, but your words, "However, you can pause and resume the download as many times as you want"  encouraged me to look deeper & try harder!!  I clicked & double-clicked (& multi-clicked!) the Mtn Lion icon in my dock to no avail but finally, I clicked & HELD the click for about 7 seconds . . . . . . . & then a little pop-up came & asked me if I want to "Resume the download" or stop it!! So I slid the cursor over to "Resume..." & it's downloading again!! ~~I HOPE!!  I guess 4.4 GB of OS update will take more than a little time to get in there!
    ~~~Again, THANK YOU so MUCH & God less you with a WONDERFUL time with your studies & future dreams!!!

    You can use iCloud with 10.7.5. You do not need to upgrade to Yosemite. You should provide a minimum of 15 GBs of free space or 10% of the hard drive's capacity, whichever is greater.
    Freeing Up Space on The Hard Drive
      1. See Lion/Mountain Lion/Mavericks' Storage Display.
      2. You can remove data from your Home folder except for the /Home/Library/ folder.
      3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
      4. Also see Freeing space on your Mac OS X startup disk.
      5. See Where did my Disk Space go?.
      6. See The Storage Display.
    You must Empty the Trash in order to recover the space they occupied on the hard drive.
    You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
    Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

  • I keep getting "hash mismatch" when trying to download Mountain Lion from the App store

    I've been trying to download the new Mountain Lion from the App Store & keep getting "hash mismatch" message. I was able to download on my 1 computer, but no luck on the 2nd computer, which is up-to-date on all updates & software. Support even put a fresh copy of the App in my account & I still get that same message. Someone suggested AppCleaner, but how do you delete the OS to re-install the new. Didn't think that was possible. Any suggestions - I've tried quitting & logging out of the App Store & even re-starting (several times)

    -  Temporarily disable anti virus software if installed.
    -  Apps such as Little Snitch, Net Nanny, and Hands Off can prevent apps from downloading including Mountain Lion.
    How to re download apps from the Mac App Store:
    Open the App Store. From the menu bar click Store > Sign In
    Click Purchases from the top of the App Store window.
    Select Mountain Lion. Then right or control click where you see Installed then click Install.
    Make sure and use the same Apple ID used for the original purchase.

  • I've downloaded OS X Mountain Lion from the App store , it still shows download on purchases . I've downloaded multiple time and still shows download.

    That Download button is telling you it is available for downloading. Since you have paid for it and you are entitled to multiple downloads, that button is correct.

    I downloaded the mountain lion from the app store and it downloaded. When i installed the mountain lion it said that the hd disk is broken and cannot be repaired, and the other disk doesnt have enough space! HELP and i cannot return to my desktop with the old sofware so i cant use my computer normaly

    This error means that your hard drive is badly corrupt and cannot be repaired by Disk Utility. Since you say you don't have backups, this is very bad news. You may already have lost data irrevocably.
    First order of business needs to be backing up whatever you can, but this may be difficult to do if the machine won't start up any more. See step 1 of the following post:
    https://discussions.apple.com/message/21614450#21614450
    Once you have backed up your data, you can address the other issues.

  • Creating my own Fusion Drive: Do I need to buy Mountain Lion from the app store to reinstall the OS? Do I lose the iLife apps?

    I just bought a Mac Mini (late 2012) with a 1TB HDD and I'm planning to install a second drive, an SSD (Samsung 840 evo) and create the Fusion Drive, and I have a couple of questions:
    1- I've read lots of articles on how to do this but I'm not sure if I have to buy Mountain Lion from the app store (to reinstall the OS after I install the second drive) since I'm not able to see it on the "Purchased" list of apps, or if I can just reinstall OS X with OS X Utilities.
    2- I read somewhere that if I make my own Fusion Drive when I reinstall OS X I will lose iLife, is this true? Or will I be able to redownload it from the store? I really don't want to lose iMovie, iPhoto and GarageBand and I'm confused about it.
    Thanks in advance for any help and information you can give me!

    Thankyou very much lllaass, that's exactly what I wanted to be sure about!

  • Just bought Mountain Lion from the app store and was installing on my MacbookPro, Now my computer is froze up and it says my HD is damaged and cant be repaired,Has anyone had this problem?

    Just bought Mountain Lion from the app store on my Macbook Pro. In the middle of installion it froze up my computer saying that the installation failed,
    It says my Hard Drive is damaged and cant be repaired. Has anyone had this problem? Im completely screwed...Thanks Apple!!

    Welcome to the Apple Support Communities,
    I had a similar issue and it was an easy fix for me. First you need to log out of your account completely in the Mac App Store. Quit the application. Re-open the Mac App Store. Click log-in, enter your Apple-ID and password. Now when the screen pops-up that has all of your billing/credit card information on it DO NOT select done. Instead select View my Account, then select View hidden purchases. There you should be able to find iPhoto. Hope this helps if not let me know. I'm still searching solutions for you.

  • How do you erase and reinstall a hard drive without a disc? I bought this mac book pro under a year ago and am pretty sure i downloaded mountain lion from the app store. Basically Im having startup issues and this is the final step Ive reached

    when I start my laptop it loads a third of the way and shuts down automaticallyI've tried to safe boot, repairing discs and clearing RAM but nothing has worked. basically I've come to the final step of having to a erase my hard drive and reinstall mountain lion however Apple support suggest that I install from a disc however I installed mountain lion from the App Store. can anyone help me go about this?

    Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • Redownloading OS X Mountain Lion from the App Store

    Hi,
    i need to re-download OS X Mountain Lion from the App Store, but cannot find the download. Trying to use my redeem code from the OS X Developer Programms tells me that the software is not available.
    How can i redownload the DMG to install Mountain Lion again ?
    Cheers,
    Oliver

    The redemption code can only be used once. If you downloaded Mountain Lion already, then in App Store sign in with the proper Apple ID. Click on the Purchases icon. Search the list for your download. If you don't see it then it may be hidden: Mac App Store- Hiding and unhiding purchases.
    If you are trying to download beta software, then:
    Please don't post here about beta software. There are confidential forums set aside for developers to use. Developer Forums. If you are a paid developer or seed tester then it's a violation of your NDA to post in these forums. If you aren't a developer or seed tester then you have an illegal copy.
