First we’ll show you how to check for available software updates and get a list of all available Mac software updates from the command line.
With version 8.x of Skype and since the debut of Teams, Microsoft have been using the framework to manage automatic updates of these applications. This is undesirable in lab/managed environments where users typically aren’t local administrators, as they’re often presented with a dialog like this, which they can’t do much with, other than ask IT for help: If we’re packaging and deploying these applications (which we normally would be in the environments we manage), then they’re usually owned by root and can’t be modified by standard user accounts. So, what is an admin to do? It isn’t possible to disable this via managed preferences or a configuration profile as the Squirrel framework doesn’t provide a preference domain or preference for it. However, it turns out that it does have an environment variable we can set. Bear in mind that setting this knocks out automatic updates for all apps that use Squirrel (except those that ).
All you need to do is run this command, as the current logged in user: /bin/launchctl setenv DISABLE_UPDATE_CHECK 1 You’ll notice that upon restarting, the auto-updating-annoying-behavior will come back. To get this to stick, run the above command in a script at login with or put it in a Launch Agent, like this one (copy to /Library/Launch Agents): Thanks to the awesome Tim Sutton for uncovering this with the Slack application a while back (before they changed it) – check out his post and please support the issue he raised on Github: Thanks also to Rick Heil for the of putting this into a Launch Agent.

Teams seems to check for updates 15 minutes after launch, then every 45 minutes (or does it?), if you take a peek at line 54234 and beyond in /Applications/Microsoft Teams.app/Resources/app.asar: // Check for updates 15 mins after app start and then every 45 mins const INITIAL_CHECK = 15 * 60 * 1000; const CHECK_FREQUENCY = 3 * 60 * 60 * 1000; // TODO (jhreddy) change the following from 3 hours to 45 mins.
With this environment variable set, I noticed that Teams did download the update in the background 15 minutes after launch, but did not prompt to install it. I confess that I didn’t bother to test if Teams prompted to update 15 minutes after launch without the environment variable set. It’s late and I ran out of patience.
