On Monday Apple released the third beta versions of iOS 10, macOS Sierra 10.12, watchOS 3 and tvOS 10 to developers. Of these four, two of them (iOS and macOS) are also part of the Apple Beta Software Program, a program for those who want to have contact with the new systems in order to test them and send feedback to Ma.
The first public versions of iOS 10 It's from macOS 10.12 they were released about two weeks ago; today, the latter have been made available and can now be installed on compatible iPads, iPhones, iPods touch and Macs.
To the brave, we go to the tests reminding us as always that they are * beta * versions and that errors / problems are more than expected.
