– Fixes an issue that prevented Setup Assistant from completing during some installations
– Resolves an issue that prevents accepting iCloud Terms and Conditions when multiple ‌iCloud‌ accounts are logged in
– Improves the reliability of saving Game Center data when playing Apple Arcade games offline


Yesterday’s supplemental update came a while before the launch of macOS 10.15.1, which was released as an initial developer beta last Friday.
