The macOS tools and support have evolved rather … notoriously. Xamarin Studio on Mac dropped support for older macOS versions, and the product eventually became Visual Studio for Mac when Microsoft acquired Xamarin. Additionally, macOS has dropped support for 32-bit applications entirely, and the older versions of MonoMac / Xamarin Studio cannot produce 64-bit applications. With these evolutions, there are now three versions of every project for the macOS build of the different components in VINTage!
