Apple on Monday released a new supplemental update for macOS Catalina, coming nearly one week after the release of the original supplemental update and two weeks following the initial launch of macOS Catalina to the public.
The update can be installed via the Software Update feature in the System Preferences app. If you have already installed the initial supplemental update it may not show up on your machine, as it appears to be a minor change, as its release notes are the same as the initial version.
The macOS Catalina Supplemental Update includes installation and reliability improvements, and is recommended for all users.
– Improves installation reliability of macOS Catalina on Macs with low disk space
– 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
The update is a stopgap update, coming ahead of macOS 10.15.1, which is currently in testing by developers.
