Hey happy Mac owners,
We have a Mac version of Insatia now! It's fully playable, in terms of gameplay and content it's the same game as Insatia on Windows and Linux, and from now on we're going to support all three platforms. In terms of codebase it's much closer to Linux version though, so it has the same known issues as the Linux one: no gamepad support, some menu settings don't work, and other small things. We'll get those done eventually.
I must admit that I have much more development experience for Linux rather than Mac, so any feedback on how it actually works on Mac (or how it doesn't work on Mac) will be priceless. Please be sure to mention your configuration (OS version, hardware) when reporting issues. Also please read about system requirements and possible caveats at the bottom of the game page.
