Apple has officially released macOS 26.6 to all users with compatible Macs, following an extensive beta testing period. This update addresses over 150 security vulnerabilities, alongside various bug fixes and performance enhancements. Notably, it resolves an issue that caused incorrect deprecation notices for certain Intel-only applications and rectifies bugs affecting Health Kit and HDR screenshots in Messages.

macOS 26.6 is also anticipated to initiate the indexing process crucial for upcoming features in macOS 27 Golden Gate, such as the new Siri AI, the dedicated Siri app, and other aspects of Apple Intelligence. While officially confirmed for iOS and iPadOS, this preparatory step is expected for macOS as well. This proactive indexing aims to shorten the wait time for users upgrading to the new version later this year, as the process can typically take several days.

The specific release build for macOS 26.6 is 25G72, a slight revision from the previous week's Release Candidate build, 25G70.
