OS X El Capitan on a Mac

Apple has released the second developer beta version of OS X El Capitan 10.11 to Mac users who are part of the registered Apple Developer program.

The updated build arrives as 15A204h and is officially labeled as OS X El Captain Developer Beta 2 1.0, separately, a second beta version of OS X Server 5.0 is also available.

Those participating in the Mac developer programs can find the downloads through the software update function of the Mac App Store, otherwise they can initiate the initial download through the Mac Dev Center website. Note if you wish to build a bootable El Capitan install drive, you will need to download the fresh installer rather than the update.

The developer releases remain intended for advanced users who are building software and testing for the future OS X 10.11 release, developer beta builds are buggy and not aimed at public usage. With that said, Mac users who do wish to run OS X El Capitan Public Beta will be able to do so in the coming month, otherwise the final release will be available this fall.

OS X El Capitan is said to heavily emphasize performance, stability, and refinements, with many under-the-hood changes which should bring welcome improvements to the Mac. Additionally, there are handfuls of new and revised features, including a revised Mission Control, a new split screen view, a new system font, enhancements to Spotlight search, and more.

Additionally, Apple has also released a second beta version of iOS 9, and of Watch OS 2.0, both are also currently exclusive to developers.

    If you are using El Capitan as a Developer right now, I don’t know why you won’t use XCode 7 Beta 2.

    If you are testing the new Capitan is great, but mac mail is failing and crash constantly with sync to gmail and external servers.

    The entire Adobe Suite CC 2015 present troubles with plug-ins, etc.

    To be honest i have 2 weeks using it and you don’t need the new tweaks, you are so custom to the Yosemite version you never notice the new tools.

    A great new feature are the 3 extra wallpapers

    Is anyone aware of any temporary solution for our now unusable Sophos antivirus protection? Since they have no plans to add El Capitan compatibility until the final version is ready, and clean/existing installs do not work, what can we do for protection in the meantime?
