New features

This update adds the following features:

Apple News:

  • Local news in your Today feed provides extensive coverage of San Francisco, the Bay Area, Los Angeles, Houston, and New York City.
  • More stories available from local news providers with a subscription to Apple News+.
  • Your daily newsletter from Apple News can now be personalized with stories that reflect your interests.

Bug fixes and improvements

  • Adds a new option to optimize video streaming on HDR-compatible Mac notebooks for improved battery life.
  • Fixes an issue where the computer name may change after installing a software update.
  • Resolves an issue where certain USB mouse and trackpads may lose connection.

Enterprise content

  • When using the built-in keyboard with a non-U.S. keyboard layout on some Mac models, passwords with certain characters are no longer rejected at the Mac login window.
  • Allows command-line tools that don't use CFNetwork, such as curl(1), to continue connecting to TLS servers that use certificates issued by the recently expired AddTrust External CA Root.
  • Major new releases of macOS can be hidden when using the softwareupdate(8) command with the --ignore flag, if the Mac is enrolled in Apple School Manager, Apple Business Manager, or a user-approved MDM. (This change also affects macOS Mojave and macOS High Sierra after installing Security Update 2020-004.)
Some features may not be available for all regions, or on all Apple devices.
