As Safari 9.0 is set to launch later this year, Apple today seeded the first developer build of Safari 9.0 to developers on the Mac App Store.
Safari 9.0 is expected to air with a number of new features alongside better performance under the hood. This includes pinned tabs, AirPlay web video without compromising the whole screen, and much more.
Registered Apple Mac Developers can grab the first developer seed of Safari 9.0 right from the Mac App Store.
