My 2 year old iMac, which has a 64 bit compatible processor, is apparently not supported by Apple. Does anyone have a workaround?

    It doesn't boot into Lion 64-bit kernel either; does not have UEFI 2.x which is the EFI64 firmware/BIOS.


    Take it with a grain of salt.


    Use "troubleshoot compatiblity mode" and find the Bootcamp64.msi and run that instead.

    I respectfully disagree. Here is a screenshot taken on my iMac about 1 minute ago. It looks to me that my system is running the 64-bit kernel.

    For anyone else having my same issue, I managed to just manually install all of the x64 drivers from the Boot Camp 4.0 disk I burned using the Boot Camp Assistant. So far, everything is working like a champ.
