Actually TAC does (or did) have a few Mac games.
They just don't support them anymore.
The following games had Mac versions published by Dreamcatcher/TAC:
Traitors Gate
Beyond Atlantis
Safecracker
Riddle of the Sphinx
Riddle of the Sphinx II: The Omega Stone
Dracula Resurrection
Dracula Last Sanctuary
The Messenger
Timescape
you can find the list
***here***Besides those, Dreamcatcher published Jewels of the Oracle and Jewels 2, which were hybrid discs and would work on both Mac OS9 and Win 95/98. They actually play better on OS9 than they do on XP because you don't have to fool with an older version of QuickTime on the Mac.
Alida (published by Got Games in the US) has a Mac OSX version, but I think the OS9 version is only available from the developer.

And of course there are older games for Mac OS9.
Some, like The Castle, Nightfall, Derrat Sorcerum, and Pegasus Prime are exclusive to the Mac.
LadyK is our resident Mac gamer. Maybe she will have some more info for you.
