Yes, it's supposed to be going through WINE, I know in the devlogs I am open about that. If you're curious as to why it isn't a native Mac app, it's because only about 0.01% of the code base supports anything but Windows, so making a native Mac app is out of scope. As for the error you're receiving, without seeing the error I don't know what the issue is, but no it's not because you're using the app that's here. The app is specifically made because it generally just works. Although, if you are getting error messages, a lot of them can be found in the FAQ, so make sure to review that.
