Apple has officially seeded developer beta 4 of iOS 10.2.1. The first developer beta did not have any major forward-facing new additions to the mix. With the minor point upgrade, Apple is focusing on fixing any issues discovered since the public release of iOS 10.2, as well as boosting overall performance.
That’s not all, Apple also released a fourth beta of what would become the third major software update to macOS Sierra since its public launch last fall. macOS Sierra 10.12.3 beta 4 (build 16D30a) is now available on Mac computers that have a prior Sierra beta installed via the Software Update mechanism in the Mac App Store’s Updates tab.
