Thanks for your quick reply.

Yes, but that will only give Apple silicon Macs access, with an M1 processor? Of course that is great, especially for the future. But existing Macbooks aren't supported with that (those with Intel CPUs), if I am not mistaken?

My RoboVM build just crashes on M1 Macs for some reason. I can't investigate, just had user reports.

I doubt building Catalyst is possible with RoboVM/libGDX. From my experience with catalyst, the natives need to be different. Even Kotlin Native does not support Catalyst builds.

We have had some success with jpackage with The Badass Runtime (based on the desktop version fo the app). We were able to create a Windows executable and a Mac .app which can run on my Core i9 Macbook pro.

But in that case Robovm bindings cannot be used, so for integration of In-App subscriptions it has to be figured out how to do that.

If RoboVM should be possible (with some modifications though for desktop) maybe our company can create an internship assignment for a trainee we can hire, to figure this out and spent a few months on it?

@MrStahlfelge Catalysy is possible be support for it is missing. Its requires separate cocoa binding and setup. Actually its very similar to having AppleTV support
