OS X 10.10 will be known as Yosemite. The latest version of the Mac operating system offers a slew of new features and improvements aimed at bridging the gap between the desktop and mobile.
And be sure to head to our WWDC 2014 page for even more coverage.
Apps in Yosemite sport a flatter, modern design, with windows that are slightly translucent.
Changes have also hit the notification center. It's been revamped, with support for widgets.
Looking for a bite to eat? Searching in Spotlight can serve up more information than ever.
With the revamped Spotlight search functionality, Yosemite will trawl through recent messages, events, and the Internet for information on whatever you're looking up.
Apple also introduced iCloud Drive; all of the content on iCloud-connected apps will be available on all of your devices, immediately.
Apple's Safari browser now offers a detailed tab view, so you can get a quick glance at all of the sites you're browsing.
Sites you're checking out on your desktop will be available too.
You can now receive iMessages and SMS messages on any Apple device you own.
If you own an iPhone, your calls will be shared too, with your Mac serving as a great big speakerphone.
Start an email on your phone, and you'll be able to finish it on your desktop.
If your phone is nearby and you're in dire need of a connection, you can create a hotspot with a single click.
Like Mavericks, OS X Yosemite will be completely free when it arrives this fall.
But we needn't wait too long -- this summer, OS X Yosemite will be available to the public as a beta preview.
