Apple Seeds Fourth OS X 10.11 El Capitan Beta to Developers

Apple today released the fourth beta of OS X 10.11 El Capitan to developers for testing purposes, two weeks after releasing the third El Capitan beta and more than a month after unveiling the new operating system at its 2015 Worldwide Developers Conference.

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

It is not clear what today's update adds to the operating system, but we will add any new features and bug fixes to this post as they're discovered. Previous betas have featured primarily under-the-hood fixes to improve performance and reliability.


OS X El Capitan builds on the features introduced with OS X Yosemite, focusing on improving performance and user experience. Behind-the-scenes improvements in El Capitan have made a number of apps and processes on the Mac much faster, and the introduction of Metal makes system-level graphics rendering 40 percent more efficient.

Along with a new systemwide font, El Capitan includes a revamped Mission Control feature, a new Split View feature for using two full-screen apps at once, deeper functionality for Spotlight, and several new features for Safari, including Pinned Sites for housing frequently visited websites and a universal mute button that quiets all tabs.

OS X 10.11 El Capitan is available to both registered developers and public beta testers. After testing is completed, Apple will release El Capitan to the public in the fall.

Hope Apple has given us a way to opt-out of the "Massive Size Pointer" feature that seems super-annoying with inability to disable...doesn't seem like you can turn it off in Mouse, Trackpad, or Accessibility Control Panels. or in Finder Prefs either!!

This comment on Macrumors story is misleading:

"OS X 10.11 El Capitan is available to both registered developers and public beta testers."

BE SPECIFIC.

DP1, DP2, DP3, DP4 are available to developers. ONLY PB1 IS AVAILABLE TO PUBLIC BETA TESTERS. NOT DP4. THERE IS NO PB2 YET.

I'm back using Yosemite, and will stay here. I don't like that cursor zoom at all, it is super-annoying! I barely shake my mouse and it looks like my cursor is doing Super Mario mushrooms. It's so bad I can't use the OS. Total flop. i will pass for now (unless somebody has a fix to disable the feature, which would be awesome!!)
ahahaha, everytime theres a new os people diss it until they realise how much they love and would never go back

some people just dont deal with evolution 2 well,

that being said yeah that cursor thing is bad
