    It was my understanding the 6770 was a reference design, would just plug and run. Ain't seeing that happen :(

    Card's a XfX 6770, Shows as:
    Ventor: ATI (0x1002)
    Device ID: 0x68ba
    Revision ID: 0x0000

    System info tells me no kext loaded, I assume there's one I have to modify, if so where?

    Thanks

    It's kinda strange that it wouldn't as I'm pretty sure the 6770 is just a 5770 with a new number. It was still a pretty decent mid-range card when they launched the 6000 series, so they kept it and just updated its name. That might be causing the system not to recognize it though?

    Given that the 5770 runs without problems, I'm pretty sure you must be able to find a kext or some firmware to flash it back to a 5770 that would make it work - that's just a guess though.

    I believe the 6870 is the 5770 updated..
    The 6970 is the updated 5870

    there is support for the card, but OSX drivers does not look for 6770 device ID. you can add ID into the driver, or edit your 6770 firmware to 5770 device id with RBE in windows.

    it is also important what OS you are on. you need Lion or mountain lion.
