I have a mac. It was really hard to find a good editor, so I made maps without a special editor.
I have found ways myself on how to make:
-Square tiles (2x1)
-Stack (right ontop)
-Player 256
-zerg+terran+protoss=player 1
I got also got sweet triggers from a good friend O)FaRTy1bilion:
-hyper
-disable units
-players 9,10,11,12
-Tons of AI scripts
He also gave me Colors and formatting skillz.
Here is a map that I made on my mac os9. with the editor from the disc
