There is no Mac compatible version of Timeline Maker, however, it can be run on a Mac with Windows emulation.

Since Mac cannot run Timeline Maker directly, there is a workaround for Mac users if they have Windows emulation software (software on mac that runs Windows for PC users).

The good folks at Paralells are an example:

When emulation software is in place on the Mac, and Windows 7 (or greater) has been installed, then you can install programs that are for PC, such as Timeline Maker Pro.
