This video shows you how to update macOS Big Sur to version 11.7.11 (build 20G1443), which is the latest and final version of Big Sur (released February 2, 2026).
To update macOS Big Sur to version 11.7.11 (build 20G1443), which is the latest and final version of Big Sur (released February 2, 2026), follow these steps. Note that this is a very minor point release Apple made years after officially ending support for Big Sur in 2023. It mainly extends certificates so features like iMessage, FaceTime, and device activation keep working past January 2027 ā there are no new security fixes beyond that.
macOS Catalina (version 10.15), originally launched in October 2019, marked a significant shift for Apple’s desktop operating system. It introduced features like Sidecar, Apple Arcade integration, the dedicated Music, TV, and Podcasts apps (replacing iTunes), enhanced security with Activation Lock, and the complete removal of 32-bit app support. After its final regular point update in 2020 (10.15.7), most users assumed Catalina had reached the end of its road, with Apple focusing on newer versions like Big Sur, Monterey, Ventura, Sonoma, Sequoia, and the current macOS Tahoe (version 26).
However, on February 2, 2026, Apple quietly released macOS Catalina 10.15.8 ā more precisely labeled as macOS Catalina Security Update 2026-001 10.15.8 (build 19H2036). This update surprised many long-time Catalina users, as it arrived over five years after the previous point release.
