Aside from releasing a sixth developer beta of iOS 10.3.3 for iPhone, iPad and iPod touch, Apple today seeded a sixth beta of the forthcoming macOS Sierra 10.12.6 software update.
macOS Sierra 10.12.6 beta 6 has a build number 16G24b.
It can be downloaded and installed on a compatible Mac using the Software Update mechanism through the Mac App Store’s Updates tab. Only Apple’s registered developers and members of the paid Apple Developer Program are allowed to beta-test macOS Sierra 10.12.6.
The new beta arrived nearly ten days following macOS Sierra 10.12.6 beta 5.
Like with iOS 10.3.3, users won’t see any important outward-facing changes in macOS Sierra 10.12.6 when it releases for public consumption. This is a point release that will fix bugs and improve the security and performance of your Mac.
Apple is currently testing macOS High Sierra with its developers ahead of its release in the fall.
