I've got a game I'm working on, so far it compiles under Windoze and Linux without too much hassle.. But I'm wondering what sort of issues I'll come up against when I try to compile on a mac (the first issue being... me not having a mac)

I know Nothing about Macs apart from they look nice..

Linux has shell scripts and the Loki installer, Windows has install shield.. What does a Mac use for installing software.

I know it's an open ended question, but I'd like to know peoples experiences of working with Cross platform games on the Mac... I'm not after a specific response.
