improbably impossible randomness

Macs wrap up their applications in "packages" that are really folders, so yes, you've got it exactly right. The folder structure is highly controlled, so the OS knows exactly where to look for the actual executable (which you've found) and its other files. The easy way to see inside from the Finder is to right-click (or control-click on a one-button system) and choose "show package contents" from the pop-up menu.

Back in the old Dominions 2 days, you had to get in there to install maps and mods, but fortunately, now you don't have to.

There are a number of us Mac users on the forums if you have any other Mac-related questions.
