Hi Tush58,
If you're seeing a Remote Management screen as soon as you connect to Wi-Fi, your M1 MacBook Air is owned by a school or business. Do NOT proceed with setup.
In this case, contact Schoolmint or the company/insitution that owns (or used to own) the Mac. If they sold or gave away the Mac, they will need to complete these steps on their side. Be sure to provide them with your Mac's serial number.
- In a web browser, log in to Apple School Manager or Apple Business Manager.
- In the left sidebar, select Devices.
- Select your device and click Release. Confirm the warning.
Once the company or institution releases your Mac, you will need to erase it and reinstall macOS. At this point, the Mac will be wholy yours; the company or institution cannot re-enroll your Mac unless they have physical possession of it AND it shows the Setup Assistant.
