OS X El Capitan Public Beta 1 Available to Download & Install for Mac Users
Apple has released the first public beta version of OS X El Capitan (10.11). Any Mac user with an Apple ID and compatible Mac can choose to download and install the public beta, though due to the nature of beta system software, this is generally only recommended for advanced users.
Interested users have multiple options for running OS X El Capitan Public Beta. The best choice for a single Mac would be to back up the Mac as usual with Time Machine, then install OS X El Capitan onto a separate partition, this maintains the primary stable OS X partition and installation and allows for a dual boot environment. Users can update existing OS X versions to the Public Beta of El Capitan, but that is not advised. Finally, users can also just run OS X El Capitan Public Beta on a separate non-primary Mac, if one is available.
Downloading & Installing OS X 10.11 El Capitan Public Beta 1
- Go here and register to enroll in and participate in the OS X El Capitan Public Beta program
- Start a back up with Time Machine and let it complete
- Download the OS X El Capitan Public Beta from the Apple website, the download goes through the Mac App Store as usual
Be advised that the download may take a while to complete as Apple servers are busy with the initial rush of interest.
Once the installer has downloaded into the /Applications/ folder, you can choose to create a bootable installer drive of the OS X El Capitan beta with any USB device if desired, this must be done before the application installer has run, as it deletes itself automatically when finished. You can also just run the application immediately if desired.
As already mentioned, it is advised to run OS X EL Capitan beta on a secondary Mac, or run it on a separate partition and dual boot the Mac with a stable OS X release. Early beta system software is notoriously buggy and can behave strangely, thus it is not intended for prime time use.
If you decide to run the OS X El Capitan Public Beta, you will want to file bug reports and issues as they are seen, this is easily done through the built-in Feedback Assistant application that comes with the beta installation. This can help to shape the future of OS X, and to inform Apple of bugs, issues, or other things which may need to be addressed before the public release this fall.
Separately, users can choose to participate in the freshly available iOS 9 public beta.
