What’s new in OS X El Capitan.
OS X El Capitan gives you simpler, smarter ways to do the things you do most with your Mac. Like working in multiple apps at the same time using Split View. Keeping your favorite websites handy with Pinned Sites. Managing your email with full-screen view and swipe gestures. And turning notes into useful checklists. Improvements under the hood make your Mac snappier and more efficient for all kinds of everyday tasks — from opening PDFs to loading your email. And with Metal for Mac, you get faster and more fluid graphics performance in games and high-performance apps.
