Apple Seeds Fifth OS X 10.11.4 El Capitan Beta to Developers and Public Beta Testers

Apple today seeded the fifth beta of an upcoming OS X 10.11.4 update to developers and public beta testers for testing purposes, just over a week after seeding the fourth OS X 10.11.4 beta and more than a month after releasing OS X 10.11.3. OS X 10.11.4 has been in testing since January 11.

The fifth OS X 10.11.4 beta, build 15E56a, can be downloaded through the Apple Developer Center (developers only) or via the Software Update Mechanism in the Mac App Store (for developers and public beta testers).

OS X 10.11.4 offers a couple of new features, such as Live Photos support in Messages, the ability to password protect notes in the Notes app, and an option to import notes from Evernote, but like the recent OS X 10.11.3 update, it appears to focus primarily on under-the-hood bug fixes and performance improvements. Almost all of Apple's OS X updates to date have been smaller updates that improve performance rather than introduce new features.

We'll update this post with any features or significant changes that are discovered in the fifth beta of OS X 10.11.4. OS X 10.11.4 is likely to see a spring release alongside iOS 9.3, tvOS 9.2, and watchOS 2.2, with the new software coming as early as March 21, the date of Apple's planned spring event.

I said few weeks ago that the real OSX is OS X 12 not the 10.11. Still on Yosemite 10.10.5 until then
El Cap is much better experience than Yosemite ever was for me.

Does it fix finder? You know, cut/paste shortcut and folders on top? Also green button needs an option to maximize rather than full screen.
Holding down the option key when clicking the green button "zooms" the window, although it doesn't maximize width-wise, only height-wise. I think it depends on the content in the window about how it behaves. But option key definitely avoids the full-screen behaviour, like all apps.
