Can't see why it wouldn't. It Just Works with FreeBSD's standard USB HID driver. Unless Apple went out of their way to break it, it'll work.Oh, and by the way (sorry about hijacking this topic), does the iMate work with 10.5? I was thinking of getting one for my Intel iMac - I really like my Extended, wanted to use it instead of the tiny and uncomfortable Pro keyboard I have here.
I think what that page might mean is that the 1st party drivers don't work with >10.4, but you don't need them.
