26 WWDC has more than 70 countries represented (80% for the first time), 350 fellows, more than 100 sessions, 150 labs and 1,000 Apple engineers. But what really matters to us is the news. Because of that, Tim Cook decided to leave the traditional bl-bl-bl aside and started talking about the OS X.
Craig Federighi took the stage to talk about the new desktop operating system. The first big choice for him was the name: OS X El Capitan. In practice, we are talking about a highly improved Yosemite, focused on experience and performance. We have a new source (San Francisco), a faster and smarter Spotlight, improved built-in apps and improvements to the system's window management.
When you shake the mouse or trackpad, the cursor becomes giant to make it easier to find; there are also new gestures in the Mail list of emails, with the trackpad, to mark emails as unread or delete / archive them; Safari finally gets fixed tabs (apparently with favicons monochrome on the tab bar); just like Chrome, Safari now also shows with a icon where sounds from websites are coming from.
Spotlight shows even more sports game results, weather forecasting can be resized and moved, and also allows Siri-type questions (like “Brain slides on El Capitan”). This type of natural search also works within apps, such as the Mail search field. Mission Control (sliding the trackpad from the bottom up) is now smoother and more practical. It is now also possible to tap outside the compose email window to access other messages or even work on multiple emails at the same time, with tabs.
El Capitan also now makes it easy to align two windows side by side, by touching the green traffic light button and choosing where you want to position it. Then it is easy to resize windows and the two are automatically adjusted. Third-party apps already did this and it was very practical, great to be now native to the system. It is simple to drag windows and apps to full screen mode or separate spaces and it is equally easy to drag another app to create a separate view, all from Mission Control.
The system also comes with a new Notes app with rich text formatting and integration with other apps / content, and the Photos app will allow you to add locations to a single image or to an entire Moment. In addition, Apple will offer editing extensions for Photos through the Mac App Store.
About performance, opening apps 1.4x faster, changing between apps 2x faster the system is all optimized. Metal, the engine from Apple for games, is now coming to the Mac. Core Animation and Core Graphics now run natively on Metal, and renders they are 50% faster with 40% better efficiency. But Metal is also great for complex / heavy apps, not just games Apple has seen phenomenal improvements with real examples, including After Effects and Illustrator; Adobe has already committed to adopting Metal in all of its apps for OS X. In fact, several companies are already committing themselves to the novelty.
The first beta of OS X El Capitan will be available today for developers. A public beta will start in July, and the launch for all will be free in the autumn of the Northern Hemisphere.
