OS X 10.19

Apple has brought the tradition of naming its computer operating system after cats to an end. From now on, the California-based company will name its software after places in California. The latest version, OS X 10.9 is called “Mavericks,” named after a surfing area not too far from Apple’s headquarters.

The software won’t be ready for the public until the fall, but a handful of features were shown off today, including:

Finder tabs: Instead of having multiple Finder windows open, you can merge those windows into a single window with multiple tabs. The feature is similar to how certain tabbed web browsers work.

Tags: When saving a document, you can assign certain tags to it (Important, Draft, In Review, etc.) and pull up files that share the same tags.

Multiple displays: When using a second display, you can access the menu bar and dock on the extra screen. You can have a full-screen app open on each screen and drag assets between the two. Connecting to an Apple TV box via Airplay will turn the TV set that the box is connected to into a third display as well.

Battery life: Mavericks users power optimization features such as compressed memory, reduction of CPU utilization and “App Nap,” which manages how apps get access to system resources.

Safari: The Safari web browser has been updated with a sidebar containing your bookmarks, Reading List and a section called “Shared Links” that contains only updates from people you follow on Twitter and LinkedIn that contain links to various web content.

iCloud Keychain: iCloud Keychain securely stores all the passwords you use for different websites on whichever Apple devices you use and automatically inputs them for you when you need them. It’ll also suggest strong passwords for new sites you join and store those for you as well.
Apps with push notifications: Similar to the little pop-up notifications you’ll get on your smartphone, Mavericks will deliver pop-up notifications for certain apps in the upper right-hand corner of your screen, many of which you can respond to without actually launching the full app.

Maps and Calendar: Apple’s Maps app sports a feature that sends directions right to your iPhone’s lockscreen. There’s also deeper integration with Calendar app: For instance, creating a new calendar item will let you designate the location of, say, a meeting and then tell you when you need to leave based on your location and your destination.
