Macintosh

This article is for games released on Mac operating systems before OS X. Believe it or not, there were games developed on Mac OS's back then. Not quite the selection Windows and DOS had, but there's a good handful worth giving a try if you've got something to run them.

Emulators
Earlier versions of Mac OS X had the "Classic mode", which could run pre-OS X applications; this function was removed with Mac OS X 10.5 "Leopard". If you're on a newer version of OSX, or another operating system, there are emulators which can act like a Mac OS of your choice. However, with most of them you need to have a ROM image of the required computer, and either a CD or disc image of the OS you want it to use.

Mini vMac is a virtual Macintosh Plus, and can run OSs from 1.1 to 7.5.5. It's for the games with black-and-white graphics.

Basilisk II a virtual 68xxx Macintosh, that runs OSs from 7.x to 8.1. You can try it with the earlier Mac games that were in color.

SoftMac is a windows-only emulator of 68xxx based Macintoshes.

Executor is a Windows/Linux emulator for 68xxx Macintoshes that used to be for-pay, but the owners released a special reg key to the public so anyone can use it now. Does not require the ROMs from the original Macintosh.

SheepShaver is a Windows/Linux/OSX emulator that works as a virtual PowerPC, and it runs OSs from 7.5.2 to 9.0.4. This might be the best replacement for Classic mode if you're on an OS X installation that doesn't have it, but it requires a ROM image and a copy of Mac OS.
