  • 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
