Hi Doolan, I've uploaded the 0.11 Mac OS X executable here.

The 0.11 executable I use is actually the 800x600 modded version posted here.

BTW, have you already got your data and config files set up?

Edit:
You have to run this from your terminal, i.e.

cd to your JA2 base directory, then

./ja2_old -fullscreen

(I've named the uploaded executable "ja2_old" simply because I've got several version in my directory. The one I use is actually "ja2-8x6" from the link above. Additionally, if you don't run Stracciatella in fullscreen mode on your Mac, it will slow down to a crawl.)
