Apple Seeds Fifth OS X El Capitan Beta to Developers

Apple today released the fifth beta of OS X El Capitan to developers for testing purposes, less than one week after releasing the fourth El Capitan beta and nearly two months after unveiling the operating system at its 2015 Worldwide Developers Conference.

Today's update is available through the software update mechanism in the Mac App Store and through the Apple Developer Center.

It is not clear if this update will add any outward-facing changes to El Capitan, as the past few betas have focused on under-the-hood performance improvements and bug fixes to optimize the operating system ahead of its public release. We'll add new features and bug fixes in beta 5 to this post should any tweaks be discovered.

As an update complementary to OS X Yosemite, OS X El Capitan builds on the myriad features introduced last year. Behind-the-scenes improvements in El Capitan make a number of apps and processes on the Mac faster, and the introduction of Metal makes system-level graphics rendering 40 percent more efficient.


El Capitan introduces a new system-wide font, a revamped Mission Control feature, a split-view feature for using two full-screen apps at once, deeper functionality for Spotlight, and improvements to Safari that include Pinned Sites and a universal mute button.

OS X 10.11 El Capitan is currently available to both registered developers and public beta testers. Apple plans to release El Capitan to the public in the fall.

Games won't use Metal unless coded to use it. And no game has been updated to use it yet. So strange you would see a dramatic improvement in games already.
This is not true... they announced that the improvements were made to the Core libraries and therefore existing apps would benefit from it as well.
