Products affected

• iMac (Summer 2000)
  

If possible, move your iMac computer to a different location to see if the condition still exists. This eliminates the possibility of environmental interference coming from objects such as metal desks/shelves, fluorescent lights, stand-alone speakers or electrical appliances.

If your iMac still has this issue, please take it to an Apple Authorized Service Provider for repair.

Note: The parenthetical product description (Summer 2000) refers to the summer of the Northern Hemisphere.
