Apple on Monday issued third betas of what would become maintenance and bug-fix updates to iOS, macOS Sierra, watchOS and tvOS. Members of the Apple Developer Program can now deploy iOS 10.3.2 beta 3 (build 14F5080a), macOS Sierra 10.12.5 beta 3 (build 16F60a), watchOS 3.2.2 beta 3 (build 14V5480a) and tvOS 10.2.1 beta 3 (build 14W5578b) through the Software Update mechanism.
The latest betas arrive a week following second betas.
iOS 10.3.2, macOS Sierra 10.12.5, watchOS 3.2.2 and tvOS 10.2.1 originally released to registered Apple developers on March 28.
iOS 10.3.2 beta 3 can be installed on an iPhone, iPad or iPod touch in Settings → General → Software Update. On your Mac, macOS Sierra 10.12.5 beta 3 can be deployed through Mac App Store’s Updates tab.
On your fourth-generation Apple TV set-top box, tvOS 10.3.2 beta 3 can be installed in Settings → System → Software Updates → Update Software.
On your Apple Watch, watchOS 3.2.2 beta 3 can be deployed in the Watch app on your iPhone by tapping My Watch → General → Software Update.
Installing the betas over the air requires an appropriate configuration profile that can be downloaded and installed on your devices through Apple’s portal for developers.
We’ll update the post with any changes discovered in the latest betas.
