, Apple focused on two major areas: user experience and performance. Improvements to window management, apps, and Spotlight search enhance the way we use our Macs, while under-the-hood additions like Metal graphics technology make everyday activities like launching apps faster.
El Capitan has the same general look as Yosemite, but it includes a new systemwide font -- San Francisco. OS X's window management feature, Mission Control, has also been revamped in the new operating system, introducing a new Split View feature that mirrors the iOS 9 multitasking feature on the iPad and allows for two full-screen apps to be used at the same time side-by-side.
Spotlight search, along with gaining deeper functionality and more sources, supports natural language input in El Capitan. Safari has gained Pinned Sites to let users pin favorite sites on the tab bar, and there's a handy new mute button that'll mute all sound coming from Safari or easily identify specific tabs playing audio.
