At the WWDC held in the Moscone Center in San Francisco yesterday, Apple's VP of Software Engineering Craig Federighi announced the newest version of the Mac OS X operating system version. Apple has dropped the big cats name theme and gone back to its roots: California. The new operating system is named looking toward the California coastline as the first inspiration: "Mavericks" (or you can simply call it OS X 10.9)

Here's a rundown on some of the more than 200 improvements coming on OS X Mavericks:

  • Finder: Getting tabs for search and browsing; Tabs can be color-coded; Finder window can be made full-screen
  • Display: Spreads menus across displays; Users can set up multiple displays for easier panning between windows; Configured to play well with Apple TV, AirPlay
  • Battery: New features include "App Nap," which redirects power to certain apps and not others; Compressed memory should reduce CPU activity by up to 72 percent
  • Safari: New home page ("Top Sites" now includes more bookmarks, reading list and shared links); Nitty-gritty improvements to enable faster Javascript and better memory usage; New social media sidebar for reading list integrations with Twitter and LinkedIn
  • iCloud: Encrypted "Keychain" for auto-suggesting passwords across multiple sites website logins, credit card numbers, account info, and Wi-Fi
  • iBooks: Finally adding access to mobile iOS libraries from desktops and laptops; Also supports textbooks. The app also provides a direct link to iBookstore.
  • Notifications: Users can reply right inside a notification (i.e. iMessage, email, IM, etc.) and FaceTime calls; Notifications will also be spread across iOS and Mac devices simultaneously
  • Maps: Users can access street maps, 3D flyover views, search points-of-interest, and get turn-by-turn directions. Routes set up on Mac can also be sent right to iPhone.
