Apple seeds first betas of iOS 10.3.3, watchOS 3.2.3, tvOS 10.2.2 and macOS Sierra 10.12.6

Apple on Tuesday seeded the first betas of iOS 10.3.3, watchOS 3.2.3, tvOS 10.2.2 and macOS Sierra 10.12.6. Registered developers can download the new releases via each platform’s respective over-the-air mechanism, or via Apple’s dev portal.

It’s not yet clear what changes are included in these updates, but given their version numbers, it’s likely they’re focused on security fixes and other under-the-hood improvements. We will let you know if anything more significant is discovered.

The betas do come at an interesting time—24 hours after the release of public updates for each OS, and just a few weeks ahead of WWDC, where Apple is expected to show off previews of the next major versions of iOS, watchOS, tvOS and macOS.
