I have Snow Leopard on a white 2010 MacBook (discontinued model as far as I know) with 2GB of memory, will I be able to upgrade to Mountain Lion with no issues? Or do I need to have more RAM in order to do the upgrade?

MacBook, Mac OS X (10.6.8)

    You don't need to install more RAM, but should anyway.


    Mountain Lion doesn't support any PowerPC applications, such as Office 2004 and earlier.

    Hard to say with the little data you provided but it sounds like it might.

    Upgrade Paths to Snow Leopard, Lion, and/or 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.


    Upgrading to Snow Leopard


    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.


    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. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.


         Snow Leopard General Requirements


           1. Mac computer with an Intel processor

           2. 1GB of memory

           3. 5GB of available disk space

           4. DVD drive for installation

           5. Some features require a compatible Internet service provider;

               fees may apply.

           6. Some features require Apple’s MobileMe service; fees and

               terms apply.


    Upgrading to Lion


    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.


    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.


         Lion System Requirements


           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,

               or Xeon processor

           2. 2GB of memory

           3. OS X v10.6.6 or later (v10.6.8 recommended)

           4. 7GB of available space

           5. Some features require an Apple ID; terms apply.


    Upgrading to Mountain Lion


    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.



         OS X Mountain Lion - System Requirements


           Macs that can be upgraded to OS X Mountain Lion


             1. iMac (Mid 2007 or newer)

             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)

             3. MacBook Pro (Mid/Late 2007 or newer)

             4. MacBook Air (Late 2008 or newer)

             5. Mac mini (Early 2009 or newer)

             6. Mac Pro (Early 2008 or newer)

             7. Xserve (Early 2009)


         Are my applications compatible?


             See App Compatibility Table - RoaringApps.


         Am I eligible for the free upgrade?


             See Apple - Free OS X Mountain Lion upgrade Program.


         For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.

    Just for the sake of having more room and or because it'll run faster? If I don't have to, I won't do it because I'm not an expert in installing my own RAM and I can't afford the price I know someone at the Apple store will be sure to charge to do it for me. Thanks for your help.

    Installing RAM


    MacBook  http://support.apple.com/kb/HT1651



    For best performance, fill both memory slots, installing an equal memory module in each slot.



    It is Important to get the Correct and Matching RAM





    That site also has videos on how to Install RAM

    About OS X Memory Management and Usage


    Using Activity Monitor to read System Memory & determine how much RAM is used

    Memory Management in Mac OS X

    Performance Guidelines- Memory Management in Mac OS X

    A detailed look at memory usage in OS X


    Understanding top output in the Terminal


    The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.


    Adding RAM only makes it possible to run more programs concurrently.  It doesn't speed up the computer nor make games run faster.  What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent.  It will improve the performance of applications that run mostly in RAM or when loading programs.


    Installing RAM yourself is not as difficult as you think it is. And, there are plenty of tutorials around to guide you.

    Alright, I'll see what I can do. I might have to ask someone I know to do it.

    Adding more memory will, in no way, affect what's on my computer (files and such), correct? Also (assuming I didn't add more ram), once I am able to, will upgrading to Mountain Lion erase what's on my computer or no?

    It is Recommended, and Prudent, to Backup your current hard drive Before attempting any Major Upgrade or Update.

    How do you back up the hard drive?

    By far the easiest way to Backup, is to use something like


    SuperDuper  http://www.shirt-pocket.com/


    or CCC  http://www.bombich.com/



    That way, should anything untoward happen during the Upgrade,


    you will NOT LOSE ANYTHING.


    (Get an EHD that is at least equal to your current Drive...)
