No new features for Big Sur, just big fixes
Apple’s support document detailing what’s new in the updates for macOS Big Sur doesn’t even include release notes for 11.6.7. Clearly, someone at Apple probably deemed 11.6.7 too minor a release to warrant updating this document. That’s quite understandable because macOS Big Sur is an older release that launched back in 2020. Big Sur currently enjoys limited support from Apple, which means it receives security patches from time to time. The current version, macOS Monterey, will also stop receiving new features after macOS Ventura—the next major release, currently being tested—arrives this fall. And when Monterey becomes available to the public, Monterey too will only continue receiving occasional bug-fix updates.
