Technical Deep Dive: The macOS Catalina 10.15.7 Installer and Supplemental Update

Version Identifier: macOS Catalina 10.15.7 (Build 19H15 and 19H2) Release Date: September 24, 2020 (Initial) / November 5, 2020 (Supplemental)

• Security patches: Kernel vulnerabilities, WebKit fixes for Safari, and mitigations for code execution bugs were part of 10.15.7.
• Stability fixes: Improvements to Bluetooth, Wi‑Fi connectivity, and external monitor behavior were commonly included.
• APFS and file system: Fixes related to APFS stability and metadata handling, including rare cases of volume mounting or snapshot issues.
• Firmware/boot issues: On some hardware, firmware update sequences caused problems; Apple iterated on installer behavior to reduce failure modes.
• Regressions: In some deployments, post-update issues affected specific third-party kernel extension (kext) drivers due to stricter KEXT signing and notarization requirements. Organizations using legacy 32-bit apps saw those apps remain incompatible, prompting migration to alternatives or virtualization.
