This is exciting. I wish I would have heard about this before signing up for a different MacOS management tool (Kandji) my main thing was the fact that SSO integration and management of built in administrator accounts was not there. Intune already had MacOS App management but it was confusing regarding how the Intune Company Portal worked. I was always wondering if the portal was going to be deprecated, there was previously no way to integrate Microsoft SSO for the user login process.
I do admin that Kandji's "Autopilot" for MacOS is really slick and certainly is nice for the remote end user during laptop deployments. I will be following this thread closely as Microsoft continues to make progress on MacOS management.
One thing that I would love across the board is a status screen that we could brand that shows MDM/MAM steps that are taking place in the background. Currently I tell users to login, plug in the laptop and leave it connected and running for at least 2 hours so it can completely update and download all the applications. It would be nice to have an initial setup status screen that shows the current remaining steps/policy updates to the end user.
