Since there is no installer for Mac for the latest version, if I copy over the installation directory from my Windows machine, I'll have the Mac libraries and other files properly updated?

I think this is right, but I'd like to confirm it here.

(*) Of course, it would be better if TGC provided both installers at the same time when releasing a new version.

Thanks

yes, that's what i did!
some directories are not relevant to mac/ios (like interpreter etc), so i just copied the ones that made sense

The Mac zip was created separately by Mike to ease Mac users introduction to AGK. I feel it better and simpler to keep everything in the main installer so no 'old' duplicate code gets left around. We might remove that mac installer in the future. For now just copy out the three relevant folders from the main AppGameKit installer.

Also, just managed to get the Windows AppGameKit IDE running at almost native speeds on a Mac using VMWare Fusion. Watch the AppGameKit youtube channel for a video on this soon!
