The GOG.com release of Tomb Raider 3 (with 1 and 2 in a bundle) works perfectly on my MacBook (CX11.01, 10.6.8, GMA 950), especially on full 1280x800 resolution. Out of the box, however, the game becomes stuck asking for a Tomb Raider 3 CD (which is untenable, since the GOG.com release shipped without a CD).
Therefore, with a little effort (see my post in the Tips and Tricks section, and this post by dudalb on the GOG forums), the game can be run in a winxp bottle and have the latest semi-official multipatch installed, which fixes remaining bugs in the game and removes the CD check at launch.
