You can use MDM commands to tell macOS clients to download updates in the background, to install previously downloaded updates, or to send a default instruction that allows the client to take appropriate action based on its current state. macOS Big Sur adds new options to give you even more control over install actions. If you need to deploy updates while a delay is active, MDM commands allow you to download and install specific updates on demand without changing delay settings.

More information about delay expirations for Apple updates is available in the manage software updates documentation in Apple Device Deployment. Your macOS clients will receive updates automatically when the delay expires. By default, updates are delayed for 30 days when these options are enabled, and you can delay the update for up to 90 days. In macOS Big Sur and later, you can also delay updates to apps like Safari.

To configure delayed software updates for macOS with MDM, use the Restrictions payload. You can still use softwareupdate -ignore on macOS Catalina 10.15.7 or macOS Mojave 10.14.6 clients to prevent installation of macOS Big Sur or macOS Monterey, but the -ignore option is no longer available in macOS Big Sur and later.
