Over the years, Apple has introduced a number of screens which appear the first time you log into a Mac and sometimes also after an OS update. Apple added a new Software Update screen as part of macOS Sequoia 15.4.0.

One thing to be aware of is that if you’re already managing the Software Update settings using a profile, this screen doesn’t actually change any settings.

I have not found a way to suppress this screen using a defaults command, but it is possible to suppress the Update Your Mac Automatically screen on macOS Sequoia using a configuration profile. For more details, please see below the jump.

The relevant preference domain and key values are below:

• Preference domain: com.apple.SetupAssistant.managed
• Key: SkipSetupItems
• Value: SoftwareUpdate

The profile is available on GitHub via the link below:
