Go to Applications in your Finder menu as done below. Find AirServer. The icon should show up in your dock.
Right click on the icon in the dock (control-click on a Mac). Choose Preferences > General. Choose:
- Fixed Password: If you don’t want students to access your AirServer at all.
- Onscreen Passcode: If you want a random code to be generated each time you activate AirServer. Recommended if you are having students project their work.
- Ask Me: If sends a message to your laptop asking if you want to have someone mirror their device.
I would recommend using one of these three options. They can use a QR code as well (new option).
