Apple today released the fourth developer preview of macOS Sierra since showing off the software update for the Mac at WWDC 2016. The latest release is available now through the Mac App Store. macOS Sierra’s headlining feature is Siri on the Mac with other features like Auto-Unlock which lets Apple Watch users skip the password login screen. Apple Pay is also coming to Safari with macOS Sierra, although we haven’t seen the feature live on the web yet.
Testing macOS Sierra currently requires a promo code for registered developers that you redeem through the Mac App Store. If you’re already testing macOS Sierra, you should see the updated version in the Updates section on your Mac. If you’re just jumping in to macOS Sierra testing with beta 4, head to Apple’s developer page to find the promo code associated with your account.
