I thought Tiger on the late 2007's was one of those things that worked if you copied it over, but balked if you tried to install it directly kind of deals, don't recall exactly.

Tiger ran on it if you had the install disks, the Mid 2007 and Late 2007 models were identical and even had the same model numbers, but the Late 2007 came with 10.5, while the Mid 2007 came with 10.4.
