Apple today seeded the fourth betas of what would become maintenance and bug-fix updates to its four major software platforms: iOS, macOS Sierra, watchOS and tvOS. Members of the Apple Developer Program can now deploy iOS 10.3.2 beta 4 (build 14F5086a), macOS Sierra 10.12.5 beta 4 (build 16F67a), watchOS 3.2.2 beta 4 (build 14V5485a) and tvOS 10.2.1 beta 4 (build 14W5583a) through the Software Update mechanism.
iOS 10.3.2 beta 4 can be installed on an iPhone, iPad or iPod touch in Settings → General → Software Update. On your Mac, macOS Sierra 10.12.5 beta 4 can be deployed through Mac App Store’s Updates tab.
On your fourth-generation Apple TV set-top box, tvOS 10.3.2 beta 4 can be installed in Settings → System → Software Updates → Update Software.
On your Apple Watch, watchOS 3.2.2 beta 4 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.
If you’ve enrolled in the Apple Beta Software Program, you can test-drive iOS and macOS betas on your own devices without being a registered Apple developer.
We’ll update the post with any changes discovered in the latest betas.
