Apple has released macOS Big Sur 11.6 to the public with security and bug fixes.
Like macOS 11.5.1 in July and 11.5.2 in August, this update has arrived without a beta period for testing. Apple lists bug fixes and security improvements in the update description.
At this time, it is unclear exactly what the new build offers, outside a maintenance and compatibility release. As macOS Monterey with a host of new features is currently being beta-tested, it seems unlikely that there will be major changes in the build.
The new macOS update will automatically download and install for users who have that option enabled. Users can also navigate to System Preferences to initiate the update manually.
Apple is in the process of testing macOS Monterey. The newest version of macOS is expected to see release in Fall 2021.
