Bonjour, depuis le nétoyage de mon imac, de fines traces violette sont présentes sur mon écran. IL est impossible de les enlever avec la chifonette apple. Comment faire ?

  1. Shut down your Mac.
  2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.
