The fifth developer betas for macOS 10.12 Sierra, tvOS 10 and watchOS 3 have been released to registered users. The new updates contain bug fixes, performance and stability improvements.
macOS 10.12 Sierra, tvOS 10 and watchOS 3 were announced at WWDC 2016.
macOS 10.12 contains a number of new features, apart from the name change from OS X to macOS, which includes Siri, redesigned notification center and widgets, auto-unlock via Apple Watch, Universal Clipboard for copy/pasting content automatically between iOS and Mac devices, Apply Pay, and much more.
Here is how you can update to the latest macOS 10.12 developer beta:
- If you already have a previous developer beta installed, open up Mac App Store and go to the Updates tab. You should see the new beta available for download.
- Download the full installer from Apple Developer Center. Check out our guide to creating a bootable USB installer for macOS 10.12 for a clean install. You can also try dual-booting macOS 10.12 with OS X if you want to preserve your current installation.
tvOS 10 has a new dark mode, redesigned Apple Music app, single-sign on for cable network apps, updates to Siri and much more.
If you are already using a tvOS 10 developer beta on your Apple TV, you can download beta 5 from Settings.
watchOS 3 has to be one of my favorite updates this year from Apple. Apps are finally fast enough to use. There is a new dock which lets you mark apps as favorites for instant access. The apps can also fetch data in the background so when you open them, they are already up to date. There are also new watch faces, complications, a Scribble keyboard that lets you swipe letters to write words (it works great), new Reminder and Homekit apps, and much more.
To update to watchOS 3, open the Apple Watch app on your iPhone and go to Settings > General > Software Update. Make sure that your Watch is charged at least 50% before you start.
We will update this post if we find any new noticeable changes in these releases.
Apple also released the fifth developer beta for iOS 10 today.
Update: Apple has released the fourth public beta for macOS 10.12 Sierra too, available for download from Mac App Store.
