Mac Standalone for OS 10.3.9?

I am running Unity 3.3 on Windows 7, and have an old Mac iBook with System 10.3.9.

I've been unable to get a standalone player to run on the Mac with either Universal or PPC exports. Standalones worked fine on this machine when exported from Unity 2.6.

Is Unity still compatible with the older Apple OS?

Thanks.
