Apple seems to have updated the compatibility text seen under iBooks created using the iBooks Author tool. The updated wording hints at two things — the imminent launch of OS X Mavericks and iPhone support for iBooks Author’s interactive ebooks.
Apple launched iBooks Author at an education focused media event last year, but strangely made the eBooks created using the tool iPad-only, which meant that Macs and iPhones couldn’t display them. While excluding Mac support made sense, since there was no iBooks for Mac back then, omitting iPhone-support seemed curious.
Apple’s finally fixing both these things, according to the updated compatibility text, which was first noticed by Macworld:
In the past, viewing an iBooks Author-created ebook online or via iTunes displayed the following message under the heading of ‘requirements’: “This book can only be viewed using iBooks 3.0 or later on an iPad. iOS 5.1 or later is required.”
While this message still shows up on the Web, visit an iBooks Author book in the iTunes Store and you’ll see the following: “To view this book, you must have an iOS device with iBooks 3.0 or later and iOS 5.1 or later, or a Mac with iBooks 1.0 or later and OS X 10.9 or later.”
With the change in wording appearing on Apple’s consumer-facing servers, it doesn’t seem too crazy to predict that the iPhone, running the final build of iOS 7, would gain iBooks Author eBook support. This could be announced at Apple’s upcoming September 10th iPhone event.
Mac support isn’t exactly surprising given that Apple had already previewed the new iBooks for Mac at WWDC, but the new wording does indicate that the public release of OS X Mavericks is right around the corner.
