Overview

  • Chrome 138 will be the last build compatible with macOS Big Sur, while Chrome 139 and later releases, due July 30, will only run on macOS Monterey or newer.
  • Users on Big Sur will see a persistent infobar in Chrome 138 warning that no further updates are available, exposing them to potential security risks without patches.
  • Google stresses that running Chrome on an unsupported operating system compromises security, and users must upgrade to a supported macOS version to continue receiving updates.
  • With Apple having ended official support for Big Sur, browsers such as Safari, Firefox and Edge remain the only updated options for users unable to upgrade.
  • Advanced users may leverage community tools like OpenCore Legacy Patcher to install newer macOS versions on older hardware and maintain Chrome compatibility.
