iBooks Author and InDesign
I downloaded the latest version of iBooks Author because I need to convert an Adobe InDesign file into an EPUB. I exported my InDesign file as an IDML file, but in Author, when I go to "Insert Chapter From...", "InDesign File (IDML)" is grayed out. What do I need to do to access this option?
iBooks Author 2.3-OTHER, OS X Mavericks (10.9.5)
