my boyfriend is having problems with his mouse. he has an imac computer with snow leapord and he is using a laser mouse by dell. that mouse always worked for him but for some reason it isnt moving at all, it's been doing that the entire day. i told him to unplug the mouse and replug it back in. he did that and it doesnt work. i don't have a mac, so i dont know much about troubleshooting it.
he does have a wireless mouse, but it needs batteries. how can he troubleshoot his mouse for his mac computer? if someone could gimme the steps ill tell him on the phone how to do it.
