Additionally, the update includes a security fix to address a problem where Disk Utility could be used to reveal the password of an encrypted AFPS volume, and the update also resolves a security bug relating to Keychain passwords. Complete security update release notes are below for those interested. The supplemental update is recommended for all macOS High Sierra users to install.

      “New downloads of macOS High Sierra 10.13 include the security content of the macOS High Sierra 10.13 Supplemental Update.”

    • Steve Bunnell says:

      Yes, the Supplemental Update is included in any new downloads of the macOS 10.13 installer from the App Store as of October 5th. See here at the bottom of the “Security” section:

    • Gorgon says:

      Yes new downloads of the macOS High Sierra Installer should have the updates included.

      However, and this is just me personally, I like to wait until the first major bug fix release is done. Here that would be macOS 10.13.1, but given all the problems I read online I might wait until macOS 10.13.3 or later this time around. High Sierra has virtually no new features, so there is little reason for most of us to update with any urgency and I have seen more people hold off on this update than perhaps any update in macOS (Mac OS, Mac OS X, OS X, toe-may-to, toe-maht-o) history.

    Good for you. But for me, I update to every new beta version. Won’t kill you, really…

  3. Lee says:

    Downloading and installing now, lets see if I can get the login screen to display without pulling the HDMI cable from the Mac mini! Oh, Apple, what about Server? iOS/WebDAVS? Turn off Guest access as default for SMB??? You know, actually make something that works for business rather than concentrating on home user crap

    • Jim says:

      Maybe one day we will get past this “stop focusing on others and focus on me” mentality when dealing with people offiering products for sell. I understand wanting new or bettrer features, but I will never understand why people get upset because someone is selling a product that doesn’t do exactly what they want specifically. It’s like they expect everyone to cater to them as a individual in a world of 7 billion.

  4. Lee says:

    What kind of response is that, work for Apple do you? Wanting to be able to log in without pulling the HDMI cable out, file sharing options that have been there in 10.11 and 10.12, is NOT thinking just about me. Pull your head out

  5. Lee says:

    Oh and the “update” fixes NOTHING!

  6. E. Yee says:

    There is a bug with this update. My cursor disappeared in some of my applications. It would reappear on my desktop if I closed the application.
