Finally: interactive iBooks come to Mac from the iPad!
You no longer need an iPad to play with the wonderfully interactive “Multitouch” books like Al Gore’s  “Our Choice“.
When Apple’s new desktop/laptop Operating System (OS) 10.9 “Mavericks” was released on Oct. 22, it included the iBooks application. This was the first time iBooks was available on anything other than an iOS device (iPod Touch, iPad and iPhone).
HOWEVER the application was riddled with bugs and features that made it quite frustrating to use.  Last week Apple provided an update for iBooks (version 1.01) that apparently alleviates these initial problems.
AGE OLD LESSON: Skip version 1 of just about anything; wait a few weeks for the bugs to be ironed out, then embrace with caution.
Mac OS 10.9 Mavericks is a FREE UPDATE from Apple. It requires that you have OS 10.6.8 or later already installed. 
On the hardware side, Mavericks is compatible with all Macs that are capable of running OS X Mountain Lion.
