    It appears while apple displays "Mac OS X cannot be installed on this computer" is displayed for poor Core Duo users, us late 2006 iMac people can install and run Lion all we want!

    the proof is in the pudding'

    So, it even though it isn't 'supported' it seems as though lion has no problem installing. everything went off without a hitch! or maybe i'm just plain lucky!

    something i've noticed but other haven't wrote about it seems, is that autocorrect from iOS is in lion! if you make a slight error, Lion will correct it and put a blue underline underneath it.

    the only sad part is that Logic Pro 9 doesn't work anymore, and i used that quite often.

    So yeah. anyone else successful with their iMac?

    Yeah, but your computer wasn't in the release notes as being unsupported.
    i wonder if mine works because it has the Core 2 Duo in it? hmmm.

    I think it doesn't work on the original Core Duo but it works with the Core 2 Duo

    Mac OS X Lion supports every computer that has an Intel Core 2 Duo processor or better.

    It doesn't matter the year, if it has a Core 2 Duo, it will run Lion. The install notes were likely referring to the Core Duo '06 models.

    I was just quoting, it sounded like some people in the thread didn't get the point, since it's a C2D machine.

    Thats really interesting.

    If someone has an iMac 2006 which won't boot Lion, can you try booting Snow Leopard with the 64-bit kernel by holding 4 and 6 on startup?

    Just a little experiment :D

    I can't. It's an arbitrary EFI limitation imposed by Apple. All C2Ds are 64bit.

    I was able to boot in 64 bit, and again, my 5,1 iMac has no problem running leopard.

    That's very bad news...are we sure of this? I have two 24" imacs circa late 2006 and I would hate to not be able to run lion on them..

    I want to able to run lion an maybe stick a fast ssd there because these machines are vintage.

    I believe this limitation applies only to this particular build of 10.7, IMHO all C2D-equipped macs WILL be supported in final build.

    It's really weird Dewroo is able to run 64bit kernel with his 5,1 iMac. Here are my specs from System Profiler:

    Model Name: iMac
    Model Identifier: iMac5,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.16 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 3 GB
    Bus Speed: 667 MHz
    Boot ROM Version: IM51.0090.B09
    SMC Version (system): 1.9f4

    And mine, for good measure.

    Model Name: iMac
    Model Identifier: iMac5,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2 GHz
    Number of Processors: 1
    Total Number of Cores: 2
    L2 Cache: 4 MB
    Memory: 2.5 GB
    Bus Speed: 667 MHz

    it seems as though it's running in 32bit mode.

    I'm just happy that my computer is happy.

    I know! i was shocked when it all worked!

    I honestly think it was because the final SL boot i did, i forced it to boot in 64bit.
    idk that might have been why it worked!

    I have the exact same spec iMac, also failed several attempts to install Lion.
    Would get the crossed out circle when trying to boot into Lion every time.

    Hope we get included in the next beta :(

    Crap!!!!

    I have a late 2006 C2D 20" and am getting the "Prohibited" sign on boot.

    If you hold down command V for vertibros boot it will say that this machine is not supported.

    For kicks I am trying a target boot mode install, this will likely not work either :/ :(

    Not sure how others say they are able to get this to work.

    Simply here are the specs from System Profiler:

    Model Name: iMac
    Model Identifier: iMac5,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.16 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 3 GB
    Bus Speed: 667 MHz
    Boot ROM Version: IM51.0090.B09
    SMC Version (system): 1.9f4

    Failed several attempts to boot into Lion, either from an external FW drive or the internal SSD upgraded drive.
    Always get the crossed out circle when trying to boot into Lion every time.

    The seed notes say late 2006 iMacs are not currently supported by this initial developer seed, so in that light it should not work, just confusing because it is a C2D although not fully 64-bit architecture.

    Looking forward to this machine being supported with the next seed release.

    * NOTE: Attached a photo of my iMac when attempting to boot into Lion with verbose mode
