[Qgis-user] Compiling QGIS3 with grass7 from MacPorts

[David Liontooth]

The compilations problems on OS X aren't serious, and I'm sure someone 
already knows how to overcome them.

Since OS X is unix, it's not really a non-native platform -- it runs the 
whole GNU tool chain. A vm is certainly an option, but this doesn't look 
hard.

Cheers,
Dave
