JoshuaHelms88: I'm on a Mac, can I use any of these games? If so, what do I have to do to get them working properly?

crazy_dave: For most of the DOSBox games, Boxer on a Mac is a great choice - it's very easy to use and just great overall. Here is a list of most if not all DOSBox games:

For Windows games I would recommend, Wineskin. It's free and very nice to use. Here is a list of games some users have tested on a Mac. It is by no means exhaustive for GOG games that work on a Mac.

This guys has some tutorials on how to get games working using WINE (wineskin) and also pre-made wineskin wrappers for many GOG games.

rampancy: Thanks again for the link to my post! :)

Yes, as he so wonderfully pointed out, pretty much any DOSBox or SCUMMVM-based game on GOG can be played with little effort on the Mac; all you need to do is run the installer from within WINE/CrossOver/Wineskin or use Universal Extractor to get at the data files. There's a running database right now of all GOG games which use DOSBox which you can use as a guide.

And of course, there's my own GOG mix which is here: http://www.gog.com/en/mix/mac_friendly_gog_games_4 - many of the games mentioned there work great on an old-school GMA 950 MacBook so they should work with just about any other Intel Mac out there.

crazy_dave: Actually I forgot to link to your (very useful I might add) how-to thread for getting games working on the Mac! I linked only to your GOGmix. So to correct my oversight:

Also it was a good thought to mention about SCUMMVM being compatible, which I likewise forgot!
