I can not switch to iOS anymore in Unity5.1 Personal (both 5.1.0f3 and 5.1.0p1). My computer is Mac Pro Retina & Yosemite. When I open the build settings, it's telling me no iOS module not loaded and a button Module Manager. Click on that button bring to a Panel with a list of module, I can not enable / disable or do anything in that panel. So is it the intended behavior or a bug or am I missing something ? Thanks a lot !
