Sync to Furthest Page Read: Whispersync technology automatically syncs your books across apps, so you can start reading on one device with the Kindle app installed, and pick up where you left off on another device with the Kindle app installed.It's a little annoying that long book names are truncated on your Kindle for Mac library page and there seems no way to change this. You can sort titles by name, author or most recently purchased but other than that there are absolutely no other preferences. You can then either transfer books from your Kindle to Kindle for Mac by clicking the rather small synchronization symbol or go directly to the Amazon site by clicking Shop In Kindle Store. When you install it for the first time, you're required to enter in your Amazon account details or sign-up for one. You can purchase books online and have them directly delivered to Kindle for Mac and then sync it with your device. Kindle for Mac is a very simple e-book reader which allows you to read and sync your library with your Kindle.
