You may have an upgrade DVD that does not work on your machine even though it may work on others. If so, you should be able to exchange it. Also, note that it is acceptable, IMO, to borrow the upgrade disk of another to update your machine assuming, of course, that you can find one that will work on your machine.
Regardless, did you try upgrading after starting up to your DVD by holding down C while starting up? If not, then try this approach.

Yes, there are problems with some of the DVDs released by Apple. But, see what I said above in this regard.

  • Can I upgrade memory on Macbook Pro 13" 2.5GHz 4GB RAM, Model Z0MT7B/A

    I have ordered a Macbook Pro from a retailer here in the UK. It ships with 4GB RAM but I know I will 8gb or possibly 16GB.
    Does anyone know whether the memory is removable and changeable in this model, as it used to be in earlier Macbook Pro 13" models?

    I'm pretty sure you can upgrade to 8, 12, or 16. As I'm looking on Other World Computing I'm seeing that for Macbook Pro's 13", 2012 - Current there are upgrades available in the sizes I mentioned. It stands to reason that the memory is changeable, seeing as how there are memory upgrades available and even videos to show you how to change the memory.

  • Can i upgrade my 2006 macbook pro's graphics card?

    I have a late 2006 MacBook Pro (MacBook Pro 2,1) and i would like to know whether or not i can upgrade the graphics card? If it is possible what are the restrictions? Thanks.

    No. The GPU is soldered onto the logic board and cannot be replaced.
    If you need to upgrade the machine, I'm afraid that the only solution is to purchase a new MacBook Pro.
    Sorry,

  • I have a MacBook 5,1 (13.3" aluminum from 2007 or 2008). Automatic updates will only let me get to OSX 10.5.8.  Can I upgrade to Snow Leopard, Lion 10.6 or even 10.6.8?  Also, will I have any issues with my iPhone if it's updated to iOS 7.1?

    I have a MacBook 5,1 (13.3" aluminum from 2007 or 2008). Automatic updates will only let me get to OSX 10.5.8.  Can I upgrade to Snow Leopard, Lion 10.6 or even 10.6.8?  Also, will I have any issues with my iPhone if it's updated to iOS 7.1?

    The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store to order Lion or Mountain Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
    System Requirements for 10.6:
    Mac computer with an Intel processor
    1GB of memory
    5GB of available disk space
    DVD drive for installation
    Some features require a compatible internet service provider: fees may apply.
    You can upgrade direct from 10.6.8 to 10.8 Mountain Lion without going through 10.7 Lion with the Late 2008 model 5,1 Aluminum Unibody. The Model 5,1 will probably run 10.9 Mavricks when it comes out.
    10.8 Mountain Lion is a download from the App Store, the price is $19.99.
    Mountain Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
    As for third party programs see this list for compatibility with 10.8 http://roaringapps.com/apps:table
    Also Mountain Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Mountain Lion.
    Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

  • I just upgraded my 2008 macbook pro to OS X Maverick from Snow Leopard but my computer is running a bit buggy and slow. How do I downgrade back down to snow leopard?

    I just upgraded my 2008 macbook pro to OS X Maverick from Snow Leopard but my computer is running a bit buggy and slow. How do I downgrade back down to snow leopard?

    You would reinstall 10.6 using your installation DVD.
    Out of curiosity, how much RAM do you have? Recent versions of OS X really shine with 4GB or more.

    MacBook upgrade possibilities - https://discussions.apple.com/message/19577869 - "The Early 2006 model 1,1 Core Duo can only run a maximum of 10.6 Snow Leopard.

  • Can I upgrade from snow leopard 10.6.8 to mountain lion? Not sure how old my MacBook is. How can I find that information?

    Can I upgrade from snow leopard 10.6.8 to mountain lion on my MacBook?

    Choose About this Mac from the Apple menu, click on More Info, and compare the model identifier with MacBook5,1, which is the earliest MacBook that can run Mountain Lion and newer.
    A MacBook older than that which has a Core 2 Duo(not Core Duo) or better CPU and at least 2GB of RAM can run Lion 10.7, which is available by clicking here. Neither Mountain Lion nor Lion support PowerPC software such as Microsoft Office 2004.

  • What is the largest hard drive I can upgrade to for MacBook Pro A1278 Early '11

    What is the largest hard drive I can upgrade to for macbook pro A1278 Early 2011?  I have seen 750GB on some websites, but I would like a 1TB  I am looking for SATA 6.0GB, 1TB 7200.  Is this dependant on the physical size of the hard drive? I have seen a height of 15mm and 9.5 mm.  How do I know what will fit??

    I have not seen any 7200 rpm 1 TB HDDs.  They all are 5400 rpm.  I would say that this HDD comes closest to your requirements.  Tomorrow, there may be others.

  • I have new iMac with Lion installed; can I get a free upgrade for my MacBook Pro?

    Hello
    I recently bought a 27" iMac with Lion installed.  Should I be able to download the upgrade for my MacBook Pro without paying.  If so what should I do.  If I go to the App Store I'll end up paying £20.99
    Any help gratefully received
    margaret

    Margaret,
    No you will need to purchase the upgrade. However if you own other Macs you want to upgrade once you have purchased Lion then you can upgrade the additional machines. Of course the additional machines must be using the same Apple ID. As long as the additional machine's meet the minimum system requirements listed below you are all set.
    General requirements
    Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
    2GB of memory
    OS X v10.6.6 or later (v10.6.8 recommended)
    7GB of available space
    Some features require an Apple ID; terms apply.
