Hi there,
I'm presenting you a free and solid way to install Planetdance on a Mac. I am using it and it's working like a charm. And it's free also, no hidden software or fees.
1) go to
https://www.portingkit.com and download the Porting kit
2) after download it, drag the .dmg on Applications folder as usual and then launch it
3) go to "All apps" section and you'll see "Custom port"; click on it
4) follow all the steps indicated in the setup process and you'll be able to have Plantedance installed on your Mac
If you encounter any issues, please feel free to comment here, present your issue and I will help you.
PS: This Porting kit is useful for installing
all windows apps on a Mac, not only this one.
