Mac users shouldn't have to install X11
Now, don't get too excited, but we've made some great progress on removing the X11 requirement on MacOS X thanks to the gtk-quartz guys. Of course, you still need Jack, so this is still not a click-n-go thing like Logic. But don't worry, we are also working on removing the need to have Logic installed. :)
It's hard to tell, but X11 isn't running at all. Stay tuned for more updates.
