If you are a developer and want to know what to expect in macOS Sierra, here is how to install the developer beta
Update March 13, 2017: Apple has just released macOS Sierra 10.12.4 beta 6 for developers. If you already have the macOS Sierra beta installed, head to Mac App Store > Updates and download away. If you’ve been waiting for beta 6 to get started with macOS 10.12.4, keep reading and we’ll walk you through the setup!
macOS Sierra is coming this fall with plenty of awesome new features that developers can take advantage of in their apps; as such, Apple is releasing early beta software so that developers can make their apps work seamlessly when the full operating system launches to the public.
Apple occasionally offers updates to iOS 10, watchOS 3, tvOS 10, and macOS Sierra as closed developer previews or public betas for iPhone, iPad, and Mac. (Sadly, no public betas for the Apple Watch or tvOS.) While the betas contain new features, they also contain pre-release bugs that can prevent the normal use of your iPhone, iPad, Apple Watch, Apple TV, or Mac, and are not intended for everyday use on a primary device. That’s why we strongly recommend staying away from developer previews unless you need them for software development, and using the public betas with caution. If you depend on your devices, wait for the final release.

How to make an archived backup of your Mac with Time Machine
Before you begin, make sure you back up your Mac. The download and installation process is fairly easy, but any time you make significant changes to your computer, you risk problems. When it comes to securing your data, it is definitely better to be safe than sorry. Even if you just backed everything up the night before, make sure your Mac is completely up-to-date.
- Connect an external hard disk or Time Capsule with a USB, FireWire, or Thunderbolt cable.
- Click on the Apple icon () in the upper left corner of your screen.
- Select System Preferences… from the dropdown menu.
- Select Time Machine in the System Preferences window.
- Turn the Time Machine slider On.
- Click Select Backup Disk and choose the disk you’d like to use.
Time Machine will format the hard drive for backups and start within two minutes.
