Apple has stopped supporting and updating the OS several years ago.

macOS 10.13.6 is the last release for High Sierra.

The last build numbers were 17G65, 17G2208, 17G2037.

Today, that OS is six generations old having been superseded by Mojave, Catalina, Big Sur, Monterey and Ventura.

Security-configuration updates

Security-configuration updates help make your Mac more secure by identifying malicious software and preventing its installation. When you restart your Mac, these updates also remove any malicious software that is identified but already installed. These security-configuration updates are installed in the background:

  • Core Services Application Configuration Data: Blocks incompatible apps from being launched
  • EFICheck AllowListAll: Verifies that Apple provided the firmware for your Mac
  • Gatekeeper Configuration Data: Helps protect your Mac from apps created by unidentified developers
  • Incompatible Kernel Extension Configuration Data: Blocks incompatible kernel extensions that may adversely affect your Mac
  • MRTConfigData: Removes known malware
  • TCC Configuration Data: Improves compatibility of specified software with macOS security features
  • XProtectPlistConfigData: Prevents known malware from running
