SMART Screen share no longer works once a user has updated to MacOS14. When you have boards mounted to the wall, connecting the laptop using wires is a step backward and also a safely hazard. Our teachers need the ability use touchback which makes your suggestion of using airplay or googlecast worthless since they do not allow touchback. Holding back updating to the latest OS on our laptops is not possible. Consider updating the SMART screen share app, OR making SMART mirror functional on the 6000 series boards.
