I Guys,


New to the forum and hope you don't mind me posting an issue question straight away but struggling to find answer or help anywhere else.


I have recently purchased an model A1150 macbook pro of a friend, it came wiped and no installation disc.


By error i used a iMac installation disc, although this gets me to installer it obviously is not the correct disc. I have a box set mac os x snow leopard disc, which has not been getting past the white screen, apple logo, spinning wheel. After a little reading on forums, i put the iMac disc in to get to installer and verify and repair discs, there was actually no issues, i then put back in the OS x SL install disc, and it loaded up, i again had to go to installer and verify and repair disc, again no issue then completed a restart and all seemed to load up fine and started installation. I went out and wife or Cat had closed the laptop and message appeared error could not install. Ever since i have been trying to load up again and cannot get past the white screen, trying PR and option keys but to no avail. Any suggestions how last night it loaded fine in the end and today not a chance. The disc seems to be working as there is a reading noise coming from it but that is all.


many Thanks

    According to this Wikipedia page (and quite a few other sources), the 2006 MacBook Pro you have is not supported by Snow Leopard.


    Apple's page is simplified, but explains it. A Core 2 Duo processor or better is required. The Mac you have is a Core Duo.

    That's not right, Kurt. Snow Leopard will run on Core Duo. Lion will not.

    Core Duos however can only run 32-bit applications. Core 2 Duo is required for 64-bit.


    Quoting directly from your link;

    Mac OS X v10.6 Snow Leopard system  requirements

    To install Snow Leopard for the first time, you must have a Mac with:

    • An Intel processor
    • An internal or external DVD drive, or DVD or CD Sharing
    • At least 1 GB of RAM (additional RAM is recommended)
    • A built-in display or a display connected to an Apple-supplied  video card supported by your computer
    • At least 5 GB of disk space available, or 7 GB of disk space if  you install the developer tools



    OS X Lion system requirements

    To use Lion, make sure your computer has the following:

    • An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
    • Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended); you can install without Mac OS X v10.6 by using an OS X Lion USB Thumb Drive, available on the Apple Online Store
    • 7 GB of available disk space
    • 2 GB of RAM

    That's kind of what I thought, but everything I looked into said all 2006 models were out. Apple's own page makes no mention of support for Core Duo Macs, only Core 2 Duo.


    I even checked everymac.com, which is normally very accurate. On the page linked to, it also says nothing for models earlier than 2008, but I looked again just now and they contradict themselves when you check out the A1150 models. All four models are listed as 10.6.8 as the newest version of OS X they can run, with the caveat:


    *This system can run the last version of Mac OS X 10.6 "Snow Leopard". However, it cannot boot in 64-bit mode nor does it support "OpenCL". It cannot run versions of Mac OS X more recent than 10.6.8.


    So it should work, but it's right at the end of supported versions of OS X for that model.

    Our other stalwart, MacTracker, says 10.6.8 for Core Duo models. (MBP1.1 and 1.2)
