MacOS Blueprint Updates Confusion

Ninyo did a fantastic little article on update management with Blueprints. I just was hoping for some clarification on the process. 

I had setup a test blueprint just as spec’ed from the article and it doesn’t act the way I would expect. 

 

I am using the Software Update Settings payload. It is configured with deferrals just like the article. I then go to “Computer Software Updates” and select the test group, select update, select “Download and Install” and “Install latest version based on device eligibility”. 

I can then see the update start to be queued on the devices Management pane.

After 10 minutes an error appears on the management pane.

OSUpdateStatus The client requested cancellation completed. 12 minutes ago

 

 

And it fails.

I am able to update the device easily and instantly with the “Software Update” payload. 

I am a bit confused on what I am doing wrong. Other combinations in the Software Updates pane fail the same way.

Well, for anyone else. I came back to it the next day and it started working on three separate test devices. I used the “Schedule Update” option in Software Update and “Install Based on Device Eligibility”. It was able to correctly choose macOS 26.1 based on my deferrals set in the Software Update Settings blueprint.

 

I guess the moral of the story is to be patient.
