Unofficial StepMania Wineskins, for 64-bit Macs!
5.1 coming soon!
This means that you can run StepMania on macOS Catalina and newer!
Note: If the Wineskin says it is broken/damaged, follow the instructions here: https://osu-mac.readthedocs.io/en/latest/install/install.html#step-2-repair-the-wineskin under alternate options but instead of ~/path/to/my/osu!.app, use the path to your StepMania Wineskin. Also, giving it a good ol' test run might help! I also recommend setting the resolution to something a bit higher, like 1440x900 or 1920x1080.
