These files are Macintosh versions of Angband 2.9.0.  There are three files:

angband-290-mac.sit
angband-290-ppc.sit

These are 68K and PPC versions of Angband 290, and can replace (or at least supplement)
the semi-fat version I uploaded earlier.

angband-290p-ppc.sit

This is an experimental version with several different patches.  I don't know if it's going
to work, but it has the fractal cave patch, the squelch patch, the ego items patch, the
weight patch, and the doors patch.
