macOS Sierra beta 8 and public beta 7 were released last night by the Apple company for Mac users around the world, the two versions being available to developers and users of the beta testing program, all of whom can install the updates from Software Update menu, Software Update a MacOS.
As usual, Apple does not say what changes are implemented for macOS Sierra beta 8 and public beta 7, but we are probably talking about solutions to general problems and performance improvements. Moreover, I don't think it is offered by the Apple company, so don't expect too much from the update.
macOS Sierra beta 8 and public beta 7 can be downloaded through the Software Update system, directly from the Mac App Store, or using the website for beta testing of Apple operating systems.
