Sorry about the Mac related problems, we don't have one to test it.
Anyway, great news, you can play Towns following the next steps:
1) Install Java (you can download it from our download page)
2) Open a terminal window and move to the game folder
3) Type the next command:
java -cp .:./lib/lwjgl.jar:./lib/lwjgl_util.jar:./lib/slick-util.jar:./xaos.jar -Djava.library.path=./lib/native/ -Dsun.java2d.opengl=false xaos.Towns
Commodore 8-bit machines, Acorn BBC, TRS-80, Apple II family, Mac OS up to version 9 and OS-9
Multics, Unix and Unix-like systems (GNU/Linux, AIX, Xenix, Mac OS X, FreeBSD, etc.), BeOS, Amiga, RISC OS, and others.
Also, a minor English correction: the past tense of "to read" (sounds like "reed", the plant) is "read" (sounds like "red", the color). It's quite strange.
Thanks for the interesting game! I played the first 2 tutorials last night, then couldn't figure out how to build walls in the 3rd tutorial mission. I think the gameplay videos had a stone-working building, but the only one I could build in that mission was the wood shop.
