A: Hello
At the moment you can transfer the project file between Mac/Win/Linux but for the compilation part you need to compile on a given Os to have the standalone work for that OS. But we have started working on a Cloud compiler that allow you to compiler the standalone for all 3 Os in one go. In the meantime we are happy to compile your Standalone for you via support ticket, just reach out to us and share the project file and we can generate a Mac, Windows or Linux compiled version: https://rtila.com/support
