For the first time ever, Apple will make its operating system entirely free.
Just by installing Mavericks on your Mac, Apple says you will get up to an hour longer of web browsing and an hour and a half longer watching content on iTunes.
A cool feature about Mavericks is that it supports Website notifications. That way, you can get notifications about your favorite sports teams from MLB.com or an item you're following on Gilt. Mavericks also features enhanced notifications so you can respond to iMessages without having to leave the app you're currently in.
Safari also got an upgrade with Mavericks. It now features shared links and accelerated scrolling.
For those who use two displays, you can now easily access the Dock on whichever screen you're working on.
