Managing macOS updates in Intune

The countdown isn't configurable by MDM currently - that would be a feature request to Apple.

I do want to highlight that enforcing an update is a very powerful action. My personal recommendation is to configure the automatic download/install update actions so that the update will attempt to install overnight or when the device has been inactive for a little bit, and then enforcing updates when absolutely necessary i.e. addressing a vulnerability, users delaying updates too long and you need to ensure device compliance, etc., outside of work hours of course
