Apple has released beta 2 of OS X 10.11.5, watchOS 2.2.1 and tvOS 9.2.1 for developers. You can grab the updates right away over the air or from the Apple Developer Program website.
Second Betas Of OS X 10.11.5, watchOS 2.2.1, tvOS 9.2.1 Have Been Released
Today is beta software day, as the Cupertino giant has released a barrage of pre-release builds for its range of devices. A short while back, Apple pushed out iOS 9.3.2 beta 2 for all registered developers, but it took things up a notch by releasing OS X 10.11.5, watchOS 2.2.1, tvOS 9.2.1 beta 2 for the Mac, Apple Watch and Apple TV 4 as well, respectively. If you're expecting something big from these betas, then you'll be disappointed. But you'll be pleased to learn that these pre-release builds do bring with them bug fixes and performance enhancements, something which we welcome at any point in time.
If you have OS X 10.11.5 El Capitan beta 1 already installed on your Mac, then you can grab the latest update from the Mac App Store itself. Make sure you have saved everything on your Mac before launching the Mac App Store, clicking on the Updates tab at the top, then installing beta 2 of OS X 10.11.5 from there. You'll also be pleased to learn that OS X 10.11.5 El Capitan beta is available as a public beta as well, details of which can be found at beta.apple.com.
watchOS 2.2.1 is also available for download, and it's a simple task of opening the Watch app on your iPhone, navigating to General > Software Update and hitting the download button there. Since watchOS updates take a while to install, therefore you'll be required to plug your Apple Watch to a power outlet before going ahead with the installation process. And if you're planning on installing watchOS 2.2.1 beta, then it should be kept in mind that it requires iOS 9.3 to be installed on your iPhone.
Lastly, tvOS 9.2.1 beta 2 can be grabbed over the air as well. Turn on your Apple TV 4 unit, head over to Settings > System, and grab the new beta OTA from there. It will take a few minutes to install, so be sure to not touch your Apple TV 4 during the installation process.
We recommend that you update all of your devices right away, so that you can reap the benefits of Apple's newly released software for its range of hardware. If there are lingering bugs from the first beta, we're hopeful that things have been ironed out in this release.
We're quite certain we'll at least see one more beta before Apple signs off its software for the final consumer release.
