GM4Mac

GM4Mac is a version of Game Maker designed for Mac OS X. It is the first version of Game Maker to run on the Macintosh. Although released after Game Maker 8.0, GM4Mac is actually Game Maker 7 running on Mac OS X, essentially. However, GM4Mac is kept separate from all other versions of Game Maker and generally seems to run on a development cycle independent of Windows Game Maker releases.

Versions
There are lite and pro versions of GM4Mac, just like Windows GameMaker versions. However, the lite version of GM4Mac lacks the functionality to create standalone games, unlike the Windows lite versions of GameMaker, which allow this. The room, path, and sprite editors also lack full functionality in the lite version. The pro version also contains an update mechanism which will allow easy implementation of bug fixes and the addition of extension packages. However, the extensions for GM4Mac are different from those of Windows versions of GameMaker.

Additional Information
No way exists of upgrading from a Windows version of Game Maker to GM4Mac, and as of this moment, Yoyo Games does not appear to have plans on implementing such an upgrade mechanism. This further suggests that GM4Mac will be entirely separate from Windows GameMaker.
