Tiny Deathstars of Foulness

By default, OS X now updates apps that are distributed through the Mac App Store (MAS). Server running on macOS Sierra is really just the Server app, sitting on the App Store, installed on a standard Mac. If the Server app is upgraded automatically, you will potentially¬†experience some adverse side effects, especially if the app is running on a Metadata Controller for Xsan, runs Open Directory, or a major release of the Server app ships. Additionally, if you are prompted to install a beta version on a production system, you could end up with issues. Therefore, in this article we’re going to disable these otherwise sweet features of OS X. To get started, first open the System Preferences. From there, click on the App Store System Preference pane. screen-shot-2016-09-25-at-5-01-45-pm From the App Store System Preference pane, uncheck the following boxes:
  • Automatically Check For Updates: Unchecking this box disables the download in the background option and the installation of app updates.
  • Automatically Download Apps Purchased on Other Macs: If you buy an upgrade, you could accidentally install that upgrade on production servers you don’t intend to install the upgrade on.
Once disabled, you’ll need to keep on top of updates in the App Store manually. My recommendation is still to create an image of your server before each update. If you see the field, click Change for “Your computer is set to receive beta software updates” and then click screen-shot-2016-09-25-at-5-04-39-pm You can also set these from the command line. To disable automatic app store updates: defaults write /Library/Preferences/com.apple.commerce AutoUpdate -bool FALSE To disable automatic macOS updates: defaults write /Library/Preferences/com.apple.commerce AutoUpdateRestartRequired -bool FALSE And to disable automatic Software Update update checks: defaults write /Library/Preferences/com.apple.SoftwareUpdate AutomaticCheckEnabled -bool FALSE Overall, be careful with automatic updates. I like leaving checking enabled so when I sit down at the console of a server I get prompted to update; however, I don’t want servers updating and restarting unless I tell them to, after I’ve performed a comprehensive regression test on the updates.
