Today, Apple began rolling out the third build of watchOS 3.2.3 for developers to debug on the Apple Watch. The company released the second beta of the future OS upgrade two weeks ago.
If your Apple Watch is registered under a Developer account, navigate to the Watch app on your paired iPhone and tap the “My Watch” tab. From there, go to General > Software Update and you should see the build ready for download. Be sure to place your iPhone on Wi-Fi while downloading this software as it’ll surely gobble up plenty of your data.
At this time, it appears that watchOS 3.2.3 will simply carry bug fixes and under-the-hood improvements. In other words, there’s not much worth noting. If you happen to notice something new or different in the latest build of watchOS, however, feel free to hit us up at firstname.lastname@example.org or on Twitter @MBEDDEDMaximum. It’s worth noting that the second watchOS 4 beta hasn’t arrived yet due to Apple likely prepping it for a release a week or two from now.
