• AutoPkg recipe override inputs and updated trust info

    What can be the issue with recipe override inputs?

  • Some basics on switching from DEPNotify to swiftDialog

    DEPNotify is a program that allows you to display a little progress screen while a Mac is getting set up via MDM and/or Munki (or some other scripts).

  • Terminal Secure Keyboard Entry and sudo with Touch ID on macOS

    At one point or another, you may have discovered that you can enable Touch ID for sudo in the macOS terminal.

  • launchctl “new” subcommand basics for macOS

    launchd For services running in the background (or foreground), macOS uses launchd (think cron jobs on Linux or scheduled tasks on Windows). Legacy Subcommands If you’ve been managing Macs for a while, you may be familiar with a particular syntax for loading launchd.

  • Using Touch ID for sudo on macOS… even after installing an OS update

    For a while, you were able to use Touch ID for sudo on macOS by editing the /etc/pam.d/sudo file to have a line like auth sufficient pam_tid.so In previous macOS versions, that file would get overwritten when you updated (say, from 13.6 to 13.6.1), but in macOS 14 (Sonoma) and supposedly in future versions, you…

  • Comparison macOS versions using Python

    At some point in a Python script, you may want to compare macOS versions (or, really, any software versions) to each other. Back in the day, you could use Python’s LooseVersion from distutils.version, but that’s now deprecated: >>> from distutils.version import LooseVersion >>> LooseVersion(‘14.0.0’) > LooseVersion(‘14.0’) True >>> LooseVersion(‘14.0.0’) == LooseVersion(‘14.0’) False >>> LooseVersion(‘14.0’) >…

  • UseAdditionalHttpHeaders preference for MunkiReport 5.8.0

    Extra preference to consider If you use authorization headers for your Mac clients to communicate with your MunkiReport server and are upgrading from MunkiReport 5.7.1 (which still uses Python 2) to MunkiReport 5.8.0 (which uses Python 3), be aware that there is an additional preference to set if you want your headers to be used:…

  • Notes on connecting a Cloud Function to Cloud SQL

    Caveat I’m not a Google Cloud Platform expert, and this isn’t a tutorial. I’m just hoping that if people run into the same errors I ran into and search for those exact error messages, that they’ll find this blog post, and maybe it’ll be helpful to them. What I found Making the connection Google’s documentation…

  • How to use Google Apps Script to get data from a connected data sheet

    Regular sheets are straightforward For a regular Google Sheets spreadsheet, it’s fairly easy to use Google Apps Script to get the data contained on a worksheet:     var spreadsheet = SpreadsheetApp.getActive();     var regularsheet = spreadsheet.getSheets()[0];     var range = regularsheet.getDataRange();     var values = range.getValues();     for ( j = 0; j < values.length; j++ ){         Logger.log(values[j][0] + ':…

  • Using Munki to “nudge” for Rapid Security Response updates (like 13.3.1 (a))

    For many MacAdmins, Nudge has been an amazing tool for bothering users to update their Macs to the latest patch. Apple threw a wrench in things by the way it implemented the 13.3.1 (a) Rapid Security Response update, so Nudge doesn’t currently (as of this writing) support Rapid Security Response updates. There would be challenges…

  • Extracting icons from Assets.car on macOS

    Acknowledgements Thanks to Karen Garner for bringing this problem to my attention, and thanks to Mike Lynn for showing the solution.

  • Testing a local timezone deadline in Nudge

    In the past year, there have been several requests to have Nudge support local time zones instead of UTC: Feature request: Support the local timezone UTC vs Local Time Feature request: use system local time instead of time for a specific time zone (e.g., Z / GMT) Turns out, as Kevin M. Cox explains in…

  • Enforcing an older force_install_after_date when importing a new Munki item version

    Problem Munki has the ability to force updates to install by a certain date, using the force_install_after_date flag, but what do you do when you have an older version you want enforced, but you also want to import a newer version into the Munki repo? If you have Slack 4.29 you want force-installed in two…

  • “Origin checking failed … does not match any trusted origins” CSRF errors in Crypt Server

    Recent changes to Crypt Server have included guards against cross-site request forgery (CSRF) attacks. If you don’t have your Crypt Server configured correctly, you may run into issues when trying to view a secret (Get Key). You can get an error like: Forbidden (403) CSRF verification failed.

  • Using the distribution-style flag in munkipkg for PreStage Enrollment in Jamf

    Even though Jamf has its own package creation tool (Jamf Composer), there are lots of great reasons to use munkipkg instead for creating custom packages, as Elliot Jordan outlines in You might like MunkiPkg. One of the keys munkipkg has is the distribution-style key (more details in the munkipkg README), which is usually fine to…
