MAME emulator for Mac?

OpenEmu

Hands down the most beautiful, elegant and functional emulator to ever grace OS X. The initial public release was loosed on December 25, 2013.

If you'd like a version that has MAME support (among other consoles not included in vanilla download), click the arrow and choose the experimental version.

Then simply install the MAME core, drag your ROMs to the Arcade window, and OpenEmu will do the rest.

Lastly, for discussions on the topic, see this thread on github.

Try MAME OS X:

http://mameosx.sourceforge.net/

• MAMEOSX 0.135 — 24 MB .dmg containing compiled version (GUI)

• source code - 14 MB .tgz containing uncompiled source

Another option is OpenEmu (which uses Modules), The latest version is quite nice looking, and is available here, or you can compile it from source, available here.

I currently use MAME Launcher as a frontend for SDLMAME, MAME OS X or MacMAME. If you use SDLMAME, along with the binary, don't forget to install the SDL Runtime Library in ~/Library/Frameworks. Then just set the correct paths in MAME Launcher.

The reason I use MAME Launcher (and SDLMAME) is because I can play a ROM (eg. ddragon.zip) simply by double-clicking on it, after setting it to open with MAME Launcher via Finder's/Path Finder's Get Info. Or even quicker, just by browsing my Games/Arcade folder in LaunchBar and press enter to run a game. Since SDLMAME is just a binary, MAME Launcher will open but will run the game immediately. If you prefer, you can use MAME Launcher as a frontend and browse/launch your ROMS from there, if you like the extra options such as screenshots, flyers, info, search, etc.
