Apple just released macOS Sierra to the public yesterday, but work on a fresh new update is already underway after Apple seeded macOS Sierra 10.12.1 to developers this morning.
Along with the new macOS Sierra beta, Apple has also released the first beta builds of iOS 10.1, tvOS 10.1 and watchOS 3.1, bringing a slew of bug fixes to every single platform as well as Portrait Mode for the iPhone 7 Plus dual-lens camera.
Apple has today rolled out its sixth beta updates for iOS 10 and watchOS 3 ahead of their public debuts this fall. iOS 10 beta 5 is also available for public testers, and all releases promise improvements to performance and stability.
Along with dropping three new beta builds for iOS 10, tvOS and watchOS this morning, Apple has seeded a fourth beta of macOS Sierra for developers to test.
The new beta is available for download directly from the Mac App Store if you have the previous build installed and comes just two weeks after Apple dropped macOS Sierra beta 3. The upcoming update for Macs brings a ton of new features, including Siri for Mac, auto-unlock with Apple Watch, Apple Pay, better iCloud integration and more.
