Bought and downloaded OSX 10.2.8, via AppStore, using my MacBook Pro.

To install onto that machine.

 

Noted that the user agreement stated that it is awwoled to be installed onto all the Mac's that I own, from that single purchase.

 

Saved the downloaded installer app, to an external drive.

 

Attached that external to my MacPro, and copied the installer app to my MacPro "applications folder" — Same place as where the file downloaded to on the MacBook Pro.

 

Opened AppStore, on the Mac Pro, so as to log in to the AppStore account, via the Mac Pro.

 

Launched the installer, from the Mac Pro, to install OS X Mountain Lion to my Mac Pro, and now I get the following error:
We could not complete you purchase. OS X Mountain Lion is not compatiable with this computer.

 

How is this so?

Is this Mac Pro, model (MacPro2,1), too old to run this new operating system? Surely not?

 

Anyone that can assist?

Mac Pro, Mac OS X (10.6.8), 2x3GHz Quad-Core Intel Xeon 24GBram

    your computer was made early/mid 2007. it is not compatible with OSX ML.

     

    Your Mac must be one of the following models:


    -iMac (Mid 2007 or newer)

    -MacBook (Late 2008 Aluminum, or Early 2009 or newer)

    -MacBook Pro (Mid/Late 2007 or newer)

    -MacBook Air (Late 2008 or newer)

    -Mac mini (Early 2009 or newer)

    -Mac Pro (Early 2008 or newer)

    -Xserve (Early 2009)

    Mountain Lion requires hardware features that were not introduced in the Mac Pro until the "Early 2008" model, not just on raw hardware specs.

    Not 100% sure about this but a lot of macs were dropped for their lack of 64bit support which ML only uses.

     

    Not being fresh here, just trying to help, but you could try googling you model number and OSX to see if other people, who have your issue, state what is blocking them from installing ML.

     

    This would give you a better understanding of the possible reason it's not supported...

    Surely if someone did do that, they wouldn't tell you on apples propietary forums.

     

    I understand your frustration but I think googling about this and figuring out for yourself at this point is your best bet.

    Sorry about being vague. I knew at one time. I think at least one requirement for ML was 64-bit EFI (boot code),

     

    My "Early 2008" Mac Pro, the earliest Mac Pro officially eligible for Mountain Lion, shows as follows:

    Model Name:          Mac Pro

      Model Identifier:          MacPro3,1

      Processor Name:          Quad-Core Intel Xeon

      Processor Speed:          2.8 GHz

      Number of Processors:          2

      Total Number of Cores:          8

      L2 Cache (per Processor):          12 MB

      Memory:          10 GB

      Bus Speed:          1.6 GHz

      Boot ROM Version:          MP31.006C.B05

      SMC Version (system):          1.25f4

     

    Note the higher Model ID, Boot ROM, and SMC Version.

    Thought that perhaps if Apple were intereseted in retaining me as a "long standing" customer, that perhaps they could pick up and respond … ?
