You know how when you buy apps at home, they show up on your computer at work, if you’re using the same iCloud account for the app store in both locations? Some companies want to disable that. To do so, send a ConfigDataInstall key into com.apple.softwareupdate, which can most easily be done with the defaults command: sudo defaults write com.apple.SoftwareUpdate ConfigDataInstall -int 0 Or to turn it back on: sudo defaults write com.apple.SoftwareUpdate ConfigDataInstall -int 1
