Who wants to make music on a lattency hugging PC... The whole MAC OSX is build with realtime processing in mind... The whole Windows PCs arent... On a Mac everything works allways and latency free...

On top of that both Logic and Mainstage are apple propriety products owned by apple... Logic comes at €200 where comparable daws like live and cubase cost €700 in their pro version... Mainstage is only €30 and comes with one of the best VST collections available... But will never be on a PC...

And Dan, indeed does not have any plans to create a MAC version, so this will probably not ever happen this decade...
