Today, at Apple's October 2013 event, the agenda consisted of OS X Mavericks, the latest iteration of the company's desktop operating system and that it'll be released today, for free.

As long as your Mac was purchased in 2007 or later, you'll be able to upgrade straight to the latest release even if you're still running Snow Leopard.

Mavericks is jam packed with features that make the most of your Mac computer. iBooks and Maps make the leap from iOS to OS X while Mavericks finally brings true Multiple Display support to Apple's OS. Other features include additions to the Finder such as Tags and Tabs and better interactive notifications (reply straight from the alert!). iCloud keychain allows you to manage your passwords and credit card details across different iOS devices allowing you to save your login details on your iOS device and use them to login on your Mac.

There are no set system requirements but you'll most likely need 2GB of RAM to get you by. Below is a full list of compatible machines.
  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Air (Late 2008 or newer)
