Apple is serving up a fresh batch of beta updates for developers today with the release of new versions of tvOS 10, watchOS 3 and macOS Sierra.

The second beta builds of the new operating systems, which were unveiled by Apple at WWDC last month, are now available in Apple’s Developer Center (along with a new iOS 10 beta that brings minor changes to the big software update).

Major changes contained in the new betas haven’t been revealed by Apple’s release notes for the software. However, we could find some minor outward-facing changes to go along with the bevy of bug fixes coming to each of the beta builds.

New macOS 3 beta

Installing macOS Sierra can be done through the Software Update section in the Mac App Store if you have the first beta build installed. Otherwise, you can grab the new build off Apple’s site and install it manually.

The first beta of macOS Sierra brought Siri, automatic unlocking, Apple Pay for the web, and Universal Clipboard to Apple’s computer line.

New tvOS 10 beta

tvOS 10 beta 2 is the most difficult to install and requires developers to plug the device into a Mac or PC over USB, unless you use this handy workaround. If you want to install watchOS 3 beta 2, you will first need to update your iPhone to iOS 10 beta 2.

The first beta of tvOS 10 made Siri more powerful on Apple TV. It also brought dark mode and a new iOS remote companion app.

New watchOS 3 beta

The first beta of watchOS 3 brought many new features and performance upgrades. Apps load more quickly, and the UI gets a major overhaul with a new app dock, Control Center and more.

It also brought new Apple Watch faces, along with a much-improved method for adding them and customizing their look.

What’s new in latest Apple betas?

The release notes for all three beta builds list the bugs Apple engineers have squashed, but they don’t mention any UI tweaks or major new features being added. We’ll let you know what we find once we get our devices updated.
