Update : iBooks Author was updated at the release of Yosemite, see this post.
Apple have disappointed a number of people by releasing Yosemite after iOS 8. You have to say that given the promised deep integration between iOS and Yosemite releasing one without the other is a strange decision. I hope that Apple don’t make another mistake in October when they are expected to release Yosemite to the public.
In the suite of iWork apps, which I greatly enjoy working with, iBooks Author stands alone as the overlooked by Apple productivity app. It didn’t receive the updated UI and features of Pages, Numbers and Keynote around the time of the release of Mavericks. It now looks pretty old, though it is still functional (some might say more functional than the others). Well if the Yosemite release goes ahead in October and iBA is not updated by that time iBook authors will be prevented from continuing their work as the app cannot open .iba files created on earlier OS’s (it can create new files). This has hampered my work flow recently.
I hope that Apple can get that fixed with an update and not upset a whole bunch more users. Additionally it will be interesting to see what Apple have to offer by way of a refresh for iBA. As long as there is no loss of functionality users should be happy.
Would this problem with iBooks Author on Yosemite be problematic for you?
