  • Using AutoPkg to distribute and test Munki 4 (or any new Munki version) in prerelease

    10 December, 2019 update: Munki 4 is now an official (not pre-) release, so the below instructions are for when the next version is in prerelease… 25 November, 2019 (original post) As of this writing, Munki 4 is in the late stages of testing (its current on release candidate 1), so if you want to […]

  • 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.

Then, Apple started having those OS upgrade installers auto-download to the /Applications folder. Then Apple made it so OS upgrades appeared as regular updates. For Mac […]

  • Scripting changing the user picture in macOS

    Sometimes, you may want to programmatically set a default user picture (with the option for the user to change it later to a picture of her own choice). You used to be able to delete the JPEGPhoto attribute and just add in a Picture attribute, but that seems to have broken somewhere between October 2018 […]
