Mountain Lion is not compatible with this computer

When will I be able to upgrade my Mac Pro to Mountain Lion: 
2 x 3 GHz Quad-Core Intel Xeon,  Memory 13gb 667 MHz DR2 FB-DIMM, 64GB free disk (system), 1TB free other disks, computer age mid 2007, Mac OS X Lion 10.7.5.
As of 11/28/12:  Mountain Lion is not compatible with this computer.

I installed Windows 8 Pro on a PC, quickly shutdown and walked it over to my Mac Pro 1,1.
5365s are 8-core and Geekbench in the 8000 pts range.
An apple 2010 refurbished is $1800 also, old 4-core 2.8 but can upgrade easily to W3680 6-core 3.33
I agree running native beats running VM
The issue with getting Windows 64-bit onto 32-bit firmware is just the install phase but a real pain. 64-bit Windows requires, if the system is EFI based. I do have one PC that does use UEFI and Windows 8, another that does not. Both are 2008-9 motherboards (Intel which supports UEFI, and Gigabyte which did not with X58). Apple of course last updated our EFI 1,1 and 2,1 back in 2007. Before UEFI was done standardized etc.

    I bought a MacBook Pro (13" retina display) today. Tried to update software. Error mesage said to ujpdate OS. When I tried to, error message said, "OS X Mountain Lion is not compatible with this computer." Anyone else had this problem? Any suggestions?

    All owners of the model seem to have the same problem. Presently there is no 10.8.2 updater for your model. The previous updater has been pulled. Wait a while and one will show up when Apple gets it fixed.

    Thanks.

    If the OP has this much RAM in their iMac, certain this Mac can run Mountain Lion.
    The reason it might not be installing is that 15 GBs of RAM.
    Your iMac should have (4) equal sized, 4 GB sticks of RAM for a total of 16 GBs.l
    If your iMac is only reporting that there is only 15 GBs of RAM, you have a RAM stick that is either not seated in its slot properly or is defective/going bad.
    This maybe the reason that it won't download it.
    Also could be you are running out of free space on your HD.
    You need, at least 15-20 % or greater free space left on your HD.

    The build of Mountain Lion (10.8.4) on your 2013 MBA is newer than what is currently available from the App Store. That accounts for the App Store blocking you. This will likely be resolved with the introduction of 10.8.5.
    True, but even so, there is no need to re-purchase and download from the App Store (not to say you're implying this, but rather just for informational purposes). When OS X 10.8.5 is released, the Software Update service will be the way to install the update, and not the retail Mac App Store.
    Hopefully, if mawy did re-purchase Mountain Lion, when Mavericks comes out then Apple will offer it to mawy for free (it's slated to be out soon).

    Does my macbook meet the requirements for the upgrade? I'm on snow leopard 10.6.8

    Welcome to the Apple Support Communities
    You have an Early 2008 MacBook, and Mountain Lion requires an Early 2009 or Late 2008 Aluminum MacBook, so stay with Snow Leopard or call Apple to purchase Lion > http://support.apple.com/kb/HE57 Check if your programs are compatible > http://www.roaringapps.com

  • "We could not complete your purchase. Mountain Lion is not compatible with this computer"

    Which is odd, because 1) I'm already running it, after upgrading from 10.8.1 and simply want to redownload the installer again, and 2) this computer is a MB Pro Retina (late 2012). I would think it's late enough.

    Greetings - joining this thread a bit late but running into the same issue. Here is my system data -- this is baffling as it appears that my Macbook Pro *does* meet the minimum system requirements for upgrade to Mountain Lion. I'm running 10.6.8 now. Any advice?

  • OS X not compatible with this computer?

    Hi All,
    I am running OS X Lion 10.7.4 on my Mac but the app store tells me that Mountain Lion is not compatible with this computer. Why?
    Thanks,
    Bill

    any 2007 model imac or later should be compatable. If it is this new check you have at least 2gb of ram and enough free disk space (20GB).

  • Have lion on 5 year old 20" mac desktop. tried to download and received a message mountain lion not compatible with this computer. anyone else have this problem?

    have lion 10.7.4 up graded from tiger 10.5.8. tried to download mountain lion but received a message that mountain lion is not compatible with my computer. anyone have this problem or suggestion?

    It's actually not the chip... it's the drivers for the video card. this is what my friend who does IT work said.
    "The drivers for your Mac's video card are not 64bit compatible even though the computer itself is. Mountain Lion has done away with all 32bit OS components so it only runs on full 64bit MAcs now"
    So even though I updated my video card to a newer version and my computer itself is 64bit... apple didn't create a driver for it that was 64 bit. My hardware is fine for this update and the chip can handle it. It can handle all my 64 bit programs just fine. It's apple forcing me to update and buy a new expensive computer. So much for long lasting computer... they last long but they won't be supported very long.
    Why not release a version of mountain lion that supports 32 bit graphics alongside the 64 bit? Wasn't that what grand central was going to accomplish? This is rubbish.
