Thanks for that question!
Back-in-the-day, the game worked on Wine, but the runtime has changed many times since then and the project uses a lot of extensions that it didn't back then.
At the moment, it's a bit difficult to find a lot of time to work on the game.
I was planning on getting back to the game this weekend, but that hasn't quite worked out so far.
Porting the game to different OSes has never been a massive focus for me in the past.
People have often wanted it ported to android and various other things.
One thing I can do right now is to let you have the source code and current file structure to go with it.

If you have a copy of Clickteam Fusion, which I doubt is likely to be that expensive these days, and is a very versatile and interesting application, then you can run the Mac OS compiler and see how far that gets.
It also has a very good and supportive forum that has helped me many times in the past.
There are quite a few extensions on it that may block the conversion process, if they aren't supported for the Mac OS runtime.
Failing that, I would get an old Windows laptop from somewhere - even a Windows XP laptop should run it, since it's only DirectX 9.
The game always gets a bit more development time in the colder months, so I can have a look into converting it then.
Moving it to Mac OS X is a lot more feasible in my view than moving it to Android, because how would you control the ship other than tapping on a little screen?
I've played shooters like Tyrian on android phones and it wasn't exactly a great experience.
Dream big and bold and daring.
