Beta 1 of macOS 10.12.6 released on Mac App Store
Apple has rolled out the first beta of macOS 10.12.6 for developer testing. This update is likely for bug fixing and security improvements.
Releases notes for the update can be seen by developers through the Mac App Store, but no specific focus areas are mentioned.
One day after the public release of macOS 10.12.5, which was previously only available for developers and public beta testers, the first beta of macOS 10.12.6 was released.
Now registered developers can download macOS 10.12.6; a public beta version may be released shortly.
We will update if any features are discovered in the new update.
