This worked before:
Download any Mac version, uncompress the file, download the v0.55.2 Windows, uncompress the file, right click the Mac version and click "show package contents", then go: "contents" - "resources" - "autorun", there should see be bunch of folders in "autorun" with one of them titled "game" now replace "game folder" in the Mac version with the "game" folder from the Windows version!
Ok, just tried it and it doesn't work with 0.55.2 and any of the previous versions unfortunately, we should just wait for the release
