Apple today released new OS betas to its registered developers. iOS 10.2.1 beta 3 (build 14D23), macOS Sierra 10.12.3 beta 3 (build 16D25a), watchOS 3.1.3 beta 2 (build 14S959) and tvOS 10.1.1 beta 2 (build 14U711) are now available for testing to the members of Apple Developer Program.
The latest builds can be installed over-the-air via the Software Update mechanism on devices that have an appropriate configuration profile installed on them.
The new builds have arrived nearly three weeks after a second beta of iOS 10.2.1 and macOS Sierra 10.12.3 released to registered developers.
After seeding iOS 10.2.1 beta 1 and macOS Sierra 10.12.3 beta 1 to members of the Apple Developer Program yesterday, Apple today released versions of these software updates for public beta-testing. If you sign up at the Apple Beta Software Program website to become a beta tester and install an appropriate configuration profile on your device, you too will be able to install the first beta of macOS Sierra 10.12.3 on your Mac and take iOS 10.2.1 for a spin on your iPhone, iPad and iPod touch.
Following yesterday's public releases of iOS 10.2, macOS Sierra 10.12.2, watchOS 3.1.1 and tvOS 10.1, Apple on Thursday seeded to its registered developers first betas of what would become minor software updates in the form of iOS 10.2.1 beta 1 (build 14D10), macOS Sierra 10.12.3 beta 1 (build 16D12b) and tvOS 10.1.1 beta 1 (build 14U707). These betas are available via Apple's portal for developers and can be installed over the air on devices with an appropriate configuration profile installed.
