When I turn iSight on I only see 1 green light on the right side of it.What's the little dot on the left side for ? Only 1 side has the green light or both sides ?
The green light is to show that the iSight is turned on and is usually on the right of it. The hole on the leftshould be the mic. If you have an iMac or a MacBook it is probably the mic. If you have a MacBook Pro the mic is inside, near the speakers (MacBook Pros don't have the hole on the left side of the iSight).
