What precise version are you running now? There never was a release 1.29f for Mac. The last vanilla release was 1.29b2. It's compatible with 1.29f for Windows as far as I know, but I don't know of any example of it working on an Intel Mac with Leopard (10.5.x). I guess it's possible that one of the earlier versions works, and if that's what you are running, that may be why you don't have all the features of 1.29f.
If you do have an earlier version, then there's an updater to version 1.29b2 linked in my signature. However, it will probably not run on your current system.
Vanilla died a long time ago when MacSoft stopped supporting it and let their Civ franchise expire. The currently supported version of Civ3 is Civ3 Complete, developed by Aspyr. It is OS X-only, and it runs native on PPC or Intel CPUs.
