When upgrading to mountain lion will it delete all my files?

Will an upgrade to mountain lion delete all my files so as to lose data or will my existing files be saved?

That's the difference between doing an upgrade or a fresh install. Mac OS 10.6 or .7 can be upgraded or even reinstalled over the top of the existing OS without affecting the user folder which contains all your documents, pictures, music, etc.
In order to do a fresh install you would have to used Disk Utility to wipe the drive before you do the installation.

  • If i upgrade to mountain lion, will I lose all my aftermarket software?

    I just got an iPad 2 & now I need to upgrade my macbook pro to mountain lion so I can activate iCloud & share media between the two. I'm worried that if I do, I will lose all my aftermarket software on my macbook, most importantly 'office for mac' as I don't have it on disc and need it.
    I was going to upgrade via the app store - can I do that without it affecting my other software?

    Welcome to the Apple Support Communities
    You won't lose anything upgrading Mac OS X. Note that Office 2004 isn't compatible with OS X Mountain Lion because it's a PowerPC application, so if you are using it, you have to upgrade to Office 2008 or 2011 first. Remember to make a Time Machine backup and/or a clone with Carbon Copy Cloner before upgrading

  • When upgrading to mountain lion, computer froze.

    When upgrading to mountain lion, computer freezed. Hearing beep from hard drive. What should I do?

    After doing what a brody suggested, try an SMC reset. The article covers when this is required, but doing this will not affect anything.
    Reset SMC
    If the problem is still there, try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

  • Hard Drive warning when upgrading to Mountain Lion. 2 try and I was able to upgrade. Software update for IPhoto, had problems restarting. Do I need my hard drive checked

    Hard Drive warning when upgrading to Mountain Lion. 2nd try and I was able to upgrade. Software update for IPhoto, had problems restarting. Do I need my hard drive checked

    Yes.
    Choose Apple menu > Restart. Hold down the Command (⌘) and R keys as your computer restarts.
    When you see a white screen with an Apple logo in the middle, you can release the keys.
    Click Disk Utility, and then click Continue.
    In the list at the left, select the item you want to repair. (Be sure to select an item that’s indented to the right in the list, not an item at the far left.)
    Click First Aid.
    If Disk Utility tells you the disk is about to fail, back it up and replace it. You can’t repair it.
    Click Repair Disk.
    If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done.
    Otherwise, you may need to do one of the following steps.
    If Disk Utility can’t repair your disk or it reports “The underlying task reported failure,” try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall Mac OS X, and then restore your backed-up data.
    If you continue to have problems with your disk, it may be physically damaged and need to be replaced

    As Austin Kinsella1 says, it's a good idea to check your program versions.

  • By upgrading to Mountain Lion will 1333mhz ram be recognized?

    Installed 8gb/1333mhz ram running snow leopard and it would crash at boot screen.  Did some research and saw my mac cant handle that and I really would like to be running 8gb, so before exchanging the ram I was curious if by upgrading to Mountain Lion, will the system then recognize and not crash with the 8gb/1333mhz ram???

    Your MBP is supposed to be using PC3-8500 DDR3 1066 MHz ram.  Macs are extremely sensitive to their memory and repeatedly have problems with ram that is not exactly in spec.  Using ram rated at a higher speed will not run faster, and in fact will not boot in most cases.
    You need to send the memory back and get the correct ram for that machine, check the Mac specialists such as OWC and Crucial for memory that is guaranteed to work.

  • Will 16Gb RAM on a Early 2011 2.7 Ghz i7 Macbook 13" cause any problem? Also i plan to upgrade to Mountain Lion, will it work?

    I want to upgrade my machine with 16 GB RAM, it already has a G.Skill single RAM chip of 8gb. need help with the following. Will upgrading to 16Gb RAM on a Early 2011 2.7 Ghz i7 Macbook 13" cause any problem? Also i plan to upgrade to Mountain Lion, will it work?

    It won't cause you any issues or problems....
    it is however, suggested you install the same brand RAM that are of the same specs....
    1333MHz........
    Installing different brands with different CL speed might cause issues....
    so if you already have a G.Skill RAM installed, then install the same brand.

  • HT4414 If I upgrade to Mountain Lion, will my Windows based apps still work or will I have to reinstall them?

    If I upgrade to Mountain Lion, will my Windows based apps still work or will I need to reinstall them?

    As I said, the Windows applications are running in the virtual machine, using the Windows system.  It is not directed affected by upgrading Mac OS X to Mountain Lion.  So you should not need to re-install anything that runs in the Windows virtual machine.
    The real question is, does Parallel Desktop, which is the Mac OS X application, work properly under Mountain Lion?  You should go to
    http://www.parallels.com/products/desktop/
    and make sure you are using the latest version that has been updated to work with Mountain Lion.

  • Is the file and apps will lost when upgrade to Mountain Lion?

    I'm currently use lion and tend to upgrade to mountain lion. is it will affect my files and apps after upgrade to it? sorry, i'm a new user of apple product.

    You mustn't lose your apps, but you have to do a backup if the upgrade fails and you can't access to OS. Also, you can check the app compatibility, but if you use Lion, you mustn't have problems with them

    Office 2004 and Other Applications Don't Work in Lion/Mountain Lion
    If you have Office 2004 which is a PPC-only suite, it will not work in Lion/Mountain Lion. You need to upgrade to Office 2011 - Mactopia - or you can try the freeware suite, Libre Office, that is functionally similar to Office 2007 for Windows except it works on Lion/Mountain Lion.
    You may want to consider as well:
    These two suites are similar to Libre Office but not as current or as well-supported:
    NeoOffice
    Open Office
    And, then there is Apple's iWork suite:
    Pages - word processing and layout
    Keynote - presentation
    Numbers - spreadsheet
    Each can open and save Office compatible files. They may be purchased separately via the Mac App Store for $19.99 each.
    As for other software, any PPC-based software will not run in Lion or Mountain Lion because Rosetta is no longer part of OS X. You will need to upgrade to Intel versions of the software.
    (Access to the Mac App Store requires Snow Leopard 10.6.6 or higher and an Apple ID.)

  • I am using lion and wonder if I upgrade to mountain lion, will I have to purchase iWorks

    Please, someone address this issue.  I wonder if I upgrade from Lion to Mountain Lion, will my applications work such as iWorks '09.
    I just purchased an iPad 2 and I understand that if I upgrade from Lion to Mountain Lion that I will be able to integrete the two better.
    Thanks so much for any input.  I have spent hours trying to find out this information on FAQs, support questions etc. on Apple.ca and
    frankly, I am getting very frustrated.
    PS - I just purchased the upgrade from Snow Leopard to Lion not even a year ago and here I am again.  Don't know what to do.

  • Upgrading to mountain lion will it erase my calendars on my devices?

    I have not upgraded to Mountain Lion yet but am ready to do so & am currently running Snow Leopard 10.6.8.  I don't use my Calendars on my iMac since I don't have icloud and am nervous that once I install Mountain Lion it will then erase all the calendars I have set up on my ipads and iphones to match the iMac.  Can anyone tell me the best way to upgrade and not lose the Calendar info I have on all my devices?  Thank you!!

    These will protect you Mac. I have no iOS devices, so can't discuss those things.
