@hugg @asymco That absolutely is part of the experience that makes Chromebooks so popular in education. The other half of “cheap and easy”.
But I disagree *strongly* that macOS is a “long” way from that. With most of the device management services schools use (such as Jamf or Mosyle; analogous to Google Admin Console) provide single sign on tools that let you do *exactly* what you describe.
@djstarr @asymco I used Jamf. I've used Google Admin Console. I've even used Apple Business Essentials (shudder).
You can do most of the same stuff on a mac, but everything is 2-3 times slower, more likely to have a surprise issue, and more likely to change how it works with a new MacOS release.
Then you get the integration: Drive, Docs, Classroom, Backup have a smoother story. These things are all possible on Macs, but the 100% Apple solution is more limiting, and the hybrid Google/Apple solution is more complex.
