macOS Catalina 10.15.8 2026-001 Update is now Available.
Today, Apple released an update for macOS Catalina. This operating system came out more than six years ago, and many of us assumed it would never receive another update again. Surprise! We now have macOS Catalina 10.15.8 (2026‑001).
This is the link for what’s new in macOS Catalina Updates. The page entry is even marked “This article has been archived and is no longer updated by Apple”
“This update extends the certification required by features such as iMessage, FaceTime, and device activation to continue working after January 2027.”
