    Way to go apple. That means if you bought a device in 2005 or 2006, then it's not supported.

    This is stupid because MBP 13 inch just got out of core 2 duo today and all the MBAs still use intel core 2 DUO processors.

    Way to read. The Core 2 Duo is supported. There are only two models, in fact, that are left out in this update: the first edition MacBook, and the first model of Intel Mac Mini. 2 models. That's it.

    No need for histrionics.

    And the first and second versions of the Intel iMac, first version of the MacBook Pro and second version of the Intel Mac mini. Have another 4 models for your list. :p

    It's not a surprise really. I didn't expect my Core Duo MacBook Pro to be supported for the next update. :)

    Wonder what the minimum ram will be. 2GB?
  6. macrumors 65816


    I think they will extend support for all Intel Macs. If not hell will break loose. :mad:

    I guess I should go with the SL big pack to upgrade my Core Duo iMac and C2D MBP.

    Wouldn't be surprised to see Core Duo orphaned. It cannot run in long mode (64 bit), which means that for Lion to be compatible with it they'd have to build fat binaries containing both 32 and 64 bit versions of applications.

    They probably want to leave 32 bit only chips behind with this release. The very last Core Duo Macs came out in 2006, so they're nearing five years old. This is not out of line with Apple's previous (PPC era) policy of discontinuing support for older systems.

    I don't like it personally but I did expect it to happen sooner or later.

    While I do have an original CD iMac, but I would rather leave it stuck in SL and get everything on 64-bit.

    Only requirement I see:

    "Ensure you are using a 64-bit, Intel-based Mac with Mac OS X v10.6.6 Snow Leopard which has at least 8 GB of free disc space."


    - Lion requires hardware with a Core 2 Duo processor or better.

    - iMac (Late 2006) is not supported for this Lion seed.

    the whole "core" line is 32 bit. intel went to 64 bit with the "core 2" line
  12. macrumors 65816


    The irony of this is that the G5s were all 64bit and it has taken like 5 years for the tech to take off. :(
  13. macrumors 6502

    That's what they said about PPC and Snow Leopard too...

    Had a hunch this would happen so I'm glad I sold my CD MBP and CD Mac mini a few months back, and got an Air instead...

    Still, some of the computers out there will be less than four years old by the time Apple makes them obsolete.

    (My guess for the next cutoff in 10.8: Macs that don't support OpenCL.)
  14. macrumors 6502a

    Great news!
    All 64-bit I assume. :)

    Apple sheds support for old hardware in new OS releases as it goes, usually hardware around 5 years old. I once made a list of minimum CPU requirements for various OS releases:

    7.6 -- Moto 68030
    8 -- Moto 68040
    8.5 -- PPC
    9.2 -- PPC G3
    10.5 -- PPC G4
    10.6 -- Intel
    10.7 -- Intel Core 2 Duo

    Your C2D MBP will be supported, at least according to the info we currently have.
  17. macrumors 65816

    Yes and we have those. My dad has a g5 imac and first gen macbook pro. And I have mac mini 166. duo but not 2 duo.

    So I guess I won't be getting lion.
  18. macrumors newbie

    Core Duo and Core Solo did not support 64 bits code, and some portion of Lion will be compiled only as 64 bits application (Finder, I believe).

    So there is probably no way to have a perfect experience with Lion on Core Solo or Core Duo.

    The real question is other : somes Core Duo / Core Solo mac accept removing the cpu and install a Core 2 Duo. With this hardware modification, Snow Leopard can run 64 bits application.

    Unfortunatelly, Lion still did not accept install on these modified mac....

    HOW TO: Install OS X Lion 10.7 on an UPGRADED Core Solo or Core Duo Mac

    Hey, I've just managed to install the Lion GM on my Mac Mini 1,1 which I upgraded with a Core 2 Duo.
