A few years ago, my brother gave me a copy of MAME for Mac. However, I never got around to installing it. This article is a instruction set on how to install it.
First of all, this one is for Mac OS X.
When first installed, it runs an audit of possible games and that is a long list.
To actually play a game, drag the ROM to your library.
This article has links to all the game ROMs and the MAME application as well.
Also there are plenty of screen shots and the comments are also useful.
See it all here.
