Even though this Jamf Nation thread is five years old, as of this writing, it’s still got the solution to the Device Signature Error – A valid device signature is required to perform the action error message.

Running commands as a user when scripting for Munki or Jamf
Munki and Jamf run as root, so scripts they execute execute as root, not user. One great way around this is to use Outset‘s login scripts (login-once, login-every), but sometimes you may have occasion to actually run a script immediately as the logged-in user. Obviously, you’ll want to get the currently logged-in user into a […]

Introduction to Nudge
What is Nudge? In 2018, Erik Gomez created Nudge, which is open source and has nine other contributors as of this writing. Part of the beauty of Nudge is its simplicity—it doesn’t actually install any updates itself (it does invoke the softwareupdate binary to check for or download Apple software updates, but it doesn’t actually […]

Yes, Munki’s makecatalogs runs on Linux
You can’t run all of Munki‘s admin tools on Linux, because some of the things the tools use involve Mac-specific tools, which is why even Munki admins who host their Munki servers on a Linux server will use a Mac for things like munkiimport.

Forcing updates to Google Chrome using Chrome preferences / a Chrome profile
Why use Chrome relaunch notification instead of Munki I’m a huge fan of using Munki to patch software on macOS, but Munki is generally polite—it usually won’t kill an application while the user is using it. There is an option in Munki to force an install after a certain date, but that will log the […]

Setting up Reposado without downloading Apple update pkgs
Reposado allows you to set up your own local repo of Apple software updates. This can be handy if you want to control the flow of updates (having a testing branch, for example, and then promoting items from testing to production). With Apple deprecating custom catalog URLs in Catalina (they still work for now, though), […]
