The Oolite game (https://github.com/OoliteProject/oolite) was originally developed on Mac but now only works on Windows and Linux using GNUstep due to the Mac architecture change a few years ago. What would be the best approach to port the application to modern Mac (with regard to the Objective-C/GNUstep part)? For example, is it best to try to use the Mac APIs directly or to compile GNUstep Base for Mac if that's possible? Are there any gotchas or blockers to look out for? Are there any examples of projects using GNUstep that work on modern Mac as well as Windows and/or Linux?
