Despite the fact that Apple's engineering team is focusing on the next version of macOS, High Sierra, the guys from Cupertino are still working on the current version, a version that will continue to receive new updates until the release of macOS 10.13. Last Tuesday Apple launched the third beta of macOS 10.12.6, a beta in as usual first of all it is only available to developers. 24 hours later, Apple has released the third beta of the same version, macOS. 10.12.6, a new update that does not offer us any important news, since the Cupertino guys are focusing on improving its stability and security.
Along with the launch of this new macOS beta, Apple has launched the public beta of iOS 10.3.3, the other operating system that is also included in the Apple beta program, where today there is neither watchOS nor tvOS , Although the latter will do so shortly as announced by Tim Cook in the last WWDC 2017. The beta versions that for now will never reach users of the public beta is watchOS, since so far it is impossible to downgrade directly from our Mac, if the device is showing operational problems after installation.
Since last June 5, many users are already testing the first beta of macOS High Sierra, a beta that is still very green, hence it is only available for developers and until the end of this is it is not expected to be launched within the public beta program. This new version of macOS does not bring us many aesthetic novelties, but rather Apple has implemented a large number of functional improvements (APFS among others), for the performance of the operating system to be much faster and more efficient.
