How do I sync downloaded PDF files in iBooks between my iPhone, iPad, and MacBook Pro?
I've combed the forums. I can't sync through iTunes. These PDF files don't show up. I've downloaded tech manuals for gear I have via manufacturer's websites. I can't populate them across my devices. I have some in iPhone, some on iPad. I have an iPhone 5, iPad2, and MacBook Pro running current software as of 11:22 AM 13 MAR 2014. Nothing has worked so far in the standard methods.
Help!
iPhone 5, iOS 7.1
