In May, 2006, Thomas Esser announced the end of support for teTeX, and recommended     
that users switch to TeX Live. The Mac world has essentially made this switch.         
Fink and MacPorts, however, still provide teTeX in their distributions.                
                                                                                       
I recommend looking at

The first is a remarkably complete subset of TeXLive, with additions, maintained by    
Gerben Wierda.                                                                         
                                                                                       
The second is the full TeX Live distribution for the Mac. TeX Live                     
runs on almost all architectures: OS X, Windows, Linux, Unix, etc.
