I'm using Xamarin Studio Community 6.3 on my Mac (OSX 10.11.6) and I can not see any reference to Xamarin.Mac or Cocoa forms when creating a new solution (see screenshot)
I tried reinstalling Xamarin Studio, and I also installed Xamarin.Mac manually (following instructions in the FAQ on this forum) but it's made no difference.
I originally installed Xamarin from the MonoDevelop site so it's possible my installations have wound up in the wrong folder or something similar, but I haven't the faintest idea where I'd look to fix this if this is the case. Any help would be appreciated. Thanks!
