GoKawiil's interpretation of the reporting above, not reported fact.
The quick succession of security updates for older macOS versions suggests Apple is maintaining active support for users not yet on the newest OS, which could reassure enterprises and individuals delaying upgrades. The parallel beta of macOS 27.3 with expanded Siri language support indicates Apple continues pushing AI features forward even as it patches legacy systems.
