How to Run Old DOS Programs on a Mac

Introduction: How to Run Old DOS Programs on a Mac

If you have DOS games and a Macintosh but not a windows PC, you can play them! No expensive software needed. I have not tested this out on any Mac OS lower than 10.4. I am sure it will work on OS 10.4 and above.

This instructable only details software games. If you have something on a floppy disk then you'll need hardware to put it on.

Step 1: Get a Game

There are several games floating around on the net. I decided to use freedoom to play. Freedoom is a .wad file, so you need another program to run it. I used Boom 2.02 becaue it works in DOS. I've not tested it on windows, but I'm sure it'd run fine in either DOSBox on Windows or in Command Prompt.

Step 2: Get DOSBox

DOSBox is freeware and can be found here for Mac OS X, windows, Linux, etc. Download it and place it wherever you want.

Step 3: Run Boom on Dosbox

This can get confusing so bear with me.
1- wherever you put Boom when you downloaded it, go to it. Right click boom and click"get info. "
2- in the "open with" menu, go to "other" and a dialog box in the applications folder opens up. Some apps are grayed out. Up at the top where it says "reccomended applications" click that and switch it to "all applications."

Step 4: Place Your Doom.wad in the Right Folder

For Boom to work, the .wad file must be in the same folder as the boom.exe file.

Step 5: Launch Boom and You're Good!

Boom will automatically detect the .wad file and run the game. If you don't have the right file, it won't run.
Happy fragging!

    I use an old MYM (MS DOS) program for all my finances, on a PC Windows XP.
    Can I transfer that to my MAC 10.8?

    yes but I'm not sure why and yes I know this posted 3 years ago

    It is available for other operating systems such as Linux also. I used Dosbox to check out old qbasic programs before I ported the software to linux.

    DOSBox is great for Windows 7 as well if you want to run full-screen DOS applications as full-screen DOS modes are not supported by Win7. 
    It's mainly promoted for games but I use it for a stock data scanning application I wrote many moons ago.
