Application icon changes via NSWorkspace.setIcon no longer being reflected in Notification Center in macOS 26.4+

Standard
https://xkcd.com/1172/

Bit of a wordy title, but since macOS 26.4 the rebranding options in both Jamf Auto Update and Notifier have stopped working, at least as far as the icons being shown in Notification Center for notifications.

This post’s header comic nods to the fact that I’m not 100% sure that the way I have been using NSWorkspace’s setIcon to update an application’s icon (and then its notifications), is an Apple approved workflow or just a happy accident.

Below, the method and madness are detailed, along with what’s broken and the ID of the feedback I logged with Apple.

PSA: Upcoming Updates to Full Disk Access in macOS

Standard

On October 2nd, Apple posted a news article on developer.apple.com, stating that:

Some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systems—including files, mail, messages, and even browsing history—without users’ full knowledge and understanding.

And:

Going forward, we will introduce additional controls to ensure that users who genuinely wish to grant an app this extraordinary level of access can only do so with very explicit user action. 

This has been posted on a few places, but I just wanted to post in case folks have missed it.

If you’re a Mac Admin, you’ll need to keep an eye on this and any changes. I’d also urge you to file feedback on this, with many fellow Mac Admins having already submitted feedback and posting it to the #apple-feedback MacAdmins Slack channel too.

Adobe Admin Console Packages – 3.0

Standard

Only 3 months ago, we announced Adobe Admin Console Packages – 2.0. Well, there have since been some changes which have required a rewrite and as new version, hence 3.0.

The primary changes are:

  • The Adobe installers are now installed locally, with the locally installed application being queried to get the required metadata.
  • Due to the above, the script AdobeAdminConsolePackagesImporter.py, now needs to be run under sudo.
  • Additionally, two new flags have been added to AdobeAdminConsolePackagesImporter.py:
    • –extract-icons: Extracts the applications icon to the recipes %RECIPE_CACHE_DIR%
    • –uninstall: Uninstalls the applications from the Mac running AdobeAdminConsolePackagesImporter.py, one the have been processed for the required metadata.
  • With macOS 15 no longer supporting bundle packages, bundle package support has been removed.
  • Recipes for 2021 and 2022 titles have been removed.
