Apple issues sixth betas of iOS 10, watchOS 3 macOS Sierra & tvOS 10, new public iOS 10 beta

Apple on Monday released a sixth developer beta of iOS 10, plus a fifth public beta, both coming less than week after the last update as the company prepares for an official launch likely to happen next month. Also released were equivalent betas of watchOS 3, tvOS 10 and macOS Sierra.

People who have the earlier iOS 10 and Sierra betas can download the new code as a direct update. Otherwise, registered developers should go to the company's official Developer portal, and the public can enroll in the Beta Software Program.

While there are public versions of iOS 10 and macOS Sierra, the new watchOS and tvOS betas are available only to developers.

Any changes are so far unknown, but the differences between Apple's recent beta releases have become increasingly minor. The last version of iOS 10, for instance, mostly made cosmetic upgrades.

All four operating systems are due to officially debut this fall. Because of how closely linked they are, some or all of them could arrive simultaneously in early September ahead of the anticipated "iPhone 7," though macOS is likely to launch later.
