Along with releasing the first ever public beta of iOS 9, Apple has also opened up OS X El Capitan to the public for beta testing as well.
The new operating system which was announced at WWDC, has been in the hands of developers for a month, but Apple is expanding testing by opening it up to anyone who registers for Apple’s public beta program.
Public beta testers can register to install the new OS X 10.11 software on their machines by visiting Apple’s Beta Software Program website. Once registered, El Capitan can be installed on your main Mac, though we recommend you create a separate partition to try it on, rather than opening your entire hard drive to the bugs and glitches that Apple is working to fix.
The public release of OS X El Capitan is slated for this fall as a free upgrade to all Mac owners. Here’s our full walkthrough on how to install it the right way on your machine.
