It seems Apple is almost on edge with OS X Mavericks development with the seeding of Developer Preview 7 of OS X Mavericks to developers last night. The iBooks Author application is now hinting at the imminent launch of OS X Mavericks and as well as the official arrival of iBooks Author to an iPhone device. The iBooks Author requires an iPad to run on iOS, but now the requirement wording in Apple Store is hinting at the support of iBooks Author in iPhone with iBooks 3.0 launch.
Apple is also bringing the iBooks 3.0 to OS X Mavericks machines this year. This is going to be the very first time Apple bringing iBooks to OS X version. The iTunes Stores requirement wording is now hinting that OS X Mavericks is round the corner for public. A new rumor claimed that Apple might release the OS X Mavericks at the upcoming September 10th media event along with major announcements of iPhone lineup 2013.
iBooks Textbooks is making its first preview on an iPhone device this year, if we believe in Requirements wording from Apple. A major change in iBooks is already expected, as Apple will be readying up a new look for iBooks in 3.0 version to finally drop the old theme of iBooks to match up with all other applications available on iOS 7. The update is also making more sense now because this year Apple will be bringing a truly 4-inch display device in iPhone lineup, and it will be pretty easier for Apple to scale down the iPad-oriented applications to iPhone devices.
