Disabling "Turn off WiFi"
Is there a way to keep someone from turning off WiFi? I have an elderly relative with an iMac running OS 10.9.5 (cannot be updated further), connected to the Internet by WiFi (too far from the router to use Ethernet). I think she inadvertently turns off her WiFi and can only reconnect by rebooting. Is there a way to prevent this? Can it be done by setting her up with a guest account that logs in automatically and cannot change settings? Thanks for your help.
