Can I upgrade from snow leopard to mountain lion without losing my data?

Have finished an upgrade to snow leopard without losing any data on each of 9 MacBook Pros so far.  (Have 9 more to go) Can I do the mountain lion upgrade on them without losing data or must I back up the detritus of 4 years use by teachers who despite all pleas have never backed up their documents?  Would appreciate a swift reply as everyone wants their mbp's back in their hands on Monday morning. My thanks in advance to any gurus who care to reply as my local gurus seem to have fled the ashram for the weekend.

Installing a new version of OS X should not lead to any data loss. Of course, it's best to have a backup if anything 'goes wrong' but simply isntalling the new OS shouldn't damage any data.

  • I can't upgrade from Snow Leopard to Mountain Lion

    I have a Mac Pro (1.1.1) running Snow Leopard (Mac OS X10.6.8.) I want to buy and upgrade to Mountain Lion. I've followed the instructions on Apples webpage http://www.apple.com/osx/how-to-upgrade/ and have (I thought) met all the criteria to upgrade. However, when I go to the app store and attempt to purchase Mountain Lion, I get the message:
    We could not complete your purchase. OS X Mountain Lion is not compatible with this computer.
    Where do I go from here?

  • Upgrade from Snow Leopard to Mountain Lion erase my Windows partition?

    Dear all,
    I know some one might have asked it but I just wanna re-confirm.
    Would the upgrade from Snow Leopard to Mountain Lion erase my Windows partition? I am currently using Bootcamp on my Macbook Pro (Late 2010 Version) and I do not have parallel desktop. I asked the same question when Lion was released, but HK Apple Store said YES and Melbourne Apple Store said no. I am a bit confused now.
    Thank you for answering. Cheers!

    Nothing.
    That said, you should ALWAYS have a backup as anything can happen at anytime.

  • Upgrading from snow leopard to mountain lion will i have trouble using my Pages and Iphoto since it's not the latest version

    I am contemplating upgrading my OS from Snow Leopard to Mountain Lion.  Currently, I don't have ICloud available on my computer.  I also keep getting messages to upgrade my IPhoto to '11 version as well as Pages.  I know, I'm behind, but my theory is if it isn't broke don't mess with it.
    My concern is I don't want to lose my pictures and YES, I have backed up with Time Machine to an external hard drive.  (I just hope that's good enough).  IF I upgrade to start using ML OS, will I need to restore anything from my external hard drive or will I be able to start using computer as if nothing changed? 
    I know enough to be dangerous and I'm hesitant to upgrade for fear of losing everything.  Would appreciate help.  Thanks!

    So it's alright to "skip" downloading the Lion version first?  I can go directly from Snow Leopard to Mountain Lion? 
    Correct, in fact, Lion is no longer directly available from the App Store.
    Also, do I need to "empty my trash"  before going forward?
    No need.

  • Search in finder doesn't find my files in OS 10.8, upgrade from snow Leopard to Mountain Lion

    after i upgraded from snow leopard to mountain lion . when i try too search files on finder . it does not find any of them although all the files are still there .so i need scroll up and down for few minutes to find my file manually . what could be the problem ?? anyone can help me with this .. thanks in advance

    Hmm... didn't help me. But, I'm glad to know that I can "refresh" the search profiles. That may come in handy in the future.
    I'm having similar problems where I can see a file from within an application, but the file doesn't show up in a Finder search. The file I see in the application also isn't visible in that application's folder (where it's supposed to be stored, in this case).
    The file exists, because I'm able to work on it from within the application. However, it can't be found on the computer by any means I have available. I've spoken with the manufacturer of the software and they told me where to look for the file, but it isn't there (as far as I can see). Of course, they suggest the Finder is "broken" and needs to be fixed. I don't think that's the case. I can easily find other files without difficulty.
    Could what I'm looking for be a "hidden" file?

  • Will upgrading from Snow Leopard to Mountain Lion create problems within Premiere projects?

    I'm looking at the probability of upgrading from Mac OSX 10.6 to 10.8 (Mountain Lion).  I have to if I want to install or upgrade just about anything at this point.
    I was hoping to wait until the latest Premiere project was finished to avoid creating possible discrepancies between how the project plays back before and after the upgrade.  I'll skip the details and just say that it might be best if I do the upgrade now and install a new GPU to help with the massive amounts of rendering/playback needed.  Will upgrading from Snow Leopard to Mountain Lion cause any likely problems?  No other Adobe apps are involved with this project.
    I'm running a Mac Pro 5,1 and Adobe CS6.  I have two separate clone drives of my current boot disk as well as a Time Machine back up.  So I can go back if I really need to.  I'll also make sure the project is saved manually elsewhere.
    Thanks for any input!

    hi tuggerose
    i think it is bad new for you. if it's any consilation i went through the same thing when i loaded mountain lion when it first came out. i think the problem is that mountain lion is a pure 64bit operating system and the software you have is 32bit. earlier os's were able to emulate 32bit but the new system does not. the answer is new software. i did it and it cost me a load of money and much angst so your not alone.

  • Time machine can not access time capsule after upgrade from snow leopard to mountain lion

    Two days ago I upgraded my 2009 17" MBP from Snow Leopard to Mountain Lion. That evening my time capsule/time machine combination worked fine and did an incremental backup of about 12 gigabyte. Yesterday - only one day later - the time machine backup did not work anymore.
    It appears that the system can not find the time capsule - even though it shows the remaining free space on the time capsule (so it did find it after all).
    The message is always the same:
    Time Machine can not complete the backup "Time Capsule"
    The image of the backup volume "/Volumes/Data/Pauls MacBookPro.sparsebundle" is not accessable (Error -1).
    I also can not delete the backup image on the time capsule since it is read-only. And I do not want to format the time caspsule yet since my wife's MBAir is also using the same time casule.
    I tried out all kinds of suggestions (hard and soft resetting both the MBP and the TC, entering the password again, setting the TC up again) all to no avail. No backup is possible anymore.

    Sounds like you got this message earlier:
    If so, see #C13 in Time Machine - Troubleshooting.
    Offhand, I don't recall anyone not being able to delete one via the Finder (but most were only backing-up one Mac, so just erased the disk).
    You may have to wait for that message to appear again (24 hours later), or you might try holding Alt/Option with the TM icon in the menubar, and select Verify Backups if it will let you.

  • Upgrade from Snow Leopard to Mountain Lion vs. date of computer

    Hello!
    Can somebody tell me if its save to update from Snow Leopard to Mountain Lion if my computer(Macbook) was manufactured in October 2008. Apple recommends that you only do it if your Macbook is from ultimo 2008, but does that include the date before mentioned?
    Secondly, what would happen if I go ahead with the installation and my computer isnt fit to run it?
    Thanks in advance, any help would be much appreciated!

    Mountain Lion can be installed on these MacBook: Late 2008 Aluminum or Early 2009 or newer. You'll need a minimum of 2GB of memory, and 4GB or more is recommended. The late 2008 MacBooks came out in mid-October 2008. You can look at those specs here to ensure your system is this model or key in your serial number here.
    You should have a clone of your system before starting the conversion. If you don't like Mountain Lion, you'll be wiping your disk clean and reinstalling the clone. Most use SuperDuper! or Carbon Copy Cloner to copy the hard drive to another hard drive.
    OS X 10.7 Lion is still available from Apple if you would rather upgrade to it, although you don't need to if you are going directly to Mountain Lion. You call your in-country online Apple store, which in the US is at 800-MY-APPLE, and order Lion. They'll send you a download code to download from the App store.

  • Upgrade from Snow Leopard to Mountain Lion: Airparrot stopped working

    Hello,
    I used airparrot on my appletv 3 and my <acbook (late 2008) to mirror my screen. However, I updated from Snow Leopard to Mountain Lion and now suddenly, Airparrot cannot find my Appletv anymore, it continues saying: "searching for devices...".
    I already tried rebooting my macbook, disconnecting the electricity of the Appletv unit and removing the Airparrot app. All without result.
    Can someone please help me as this is the only functionality I use my AppleTV for... I want to cry.... I can't even remember why I wanted to upgrade to Mountain Lion except curiosity!
    Any insight is much appreciated.

    I don't use Air Parrot, so you should wait to talk to their tech support to see what they suggest before looking for an issue with OS X. I know nothing about using Airplay, but here's a bunch of help stuff:
    About AirPlay and Airplay Mirroring
    AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.

  • Do I need to update Bootcamp 3.3 after upgrading from Snow Leopard to Mountain Lion?

    Do I need to update Bootcamp 3.3 after upgrading directly from Snow Leopard to Mountain Lion? If so, what is the recommended version for my machine?
    Other pros and cons we should consider? Not sure what is considered best practice.
    We have a mid-2011 iMac (12,1) running Win7 64bit. Concerned about firmware updates not being compatible with Bootcamp 3.3. Firmware updates forThunderbolt port were part of post-Mountain Lion updater install. Not sure what other firmware/boot changes might have been applied to support the new recovery partition, for example. Will the 3.3 windows control panel still work safely?
    Win7 still boots OK, at least for now. Backup is current.
    I'd like to get the entire machine current again. Bootcamp 5.0 didn't want to download (appeared to hang writing to my external drive, which is otherwise fine). Bootcamp 4.1 refused to install on Win7 (claimed it wasn't for my machine, so I aborted. Downloaded from apple support page directly).
    I've searched the forums for this specific question - I see plenty of info for upgrading Bootcamp 4 to 5, but nothing for 3 to 5.
    Thanks much in advance,
    -b

    Appreciate the quick response.
    There are basically 2 schools of thought here:
    - If it ain't broke, don't fix it.
    - Don't fall off the upgrade cycle (apply patches whether you have an issue or not in order to ward off trouble before it happens).
    I don't have a specific issue that I'm chasing on the Win7 side right now. I'm attempting to address having fallen off the upgrade cycle by staying on Snow Leopard too long.
    I appreciate that the Win7 side under bootcamp is its own thing (upgrades to Mac OS don't cross over or effect the bootcamp partition) - except where firmware upgrades coming out of Mountain Lion change the hardware interface to Win7. Hence my questions.
