OS X El Capitan Developer Beta 1 Available to Download for Mac Devs
Apple has released the first beta version of OS X El Capitan to users participating as registered Mac developers. The OS X 10.11 beta 1 build is 15A178w and downloads through the App Store, the release is compatible with all Macs that are able to support and run OS X Yosemite.
Users who are registered as Apple Developers can find OS X El Capitan Beta 1 here at the developer website for OS X, you must be logged into a developer account to access the download.
If you are not a registered developer, you’ll either have to wait for the public release, or become a developer. Technically, anyone can sign up for the program for a $99 annual fee, which grants access to download beta system software and other tools aimed at those building software for Apple platforms. Alternatively, Mac users who wish to participate in beta programs but who do not want to be full fledged developers can opt to be included in the OS X Public Beta program instead, which will include OS X El Capitan in July.
As usual with installing beta software, be sure to back up the Mac beforehand, and ideally, run the beta system software on secondary hardware or at least a separate partition.
OS X El Capitan is the next version of Mac system software, focusing on performance improvements and feature enhancements, and will be released to the general public this fall as a free download.
Registered Apple developers will also find iOS 9 beta 1 available to download at the dev center website.
