Last, but Not Least

Carrying your MacBook If you carry your MacBook in a bag or briefcase, make sure

that there are no loose items (such as paper clips or coins) that could accidentally get

inside the computer through vent openings or the optical drive slot or get stuck inside

a port. Also, keep magnetically sensitive items away from the MagSafe power port.

Using connectors and ports Never force a connector into a port. When connecting a

device, make sure the port is free of debris, that the connector matches the port, and

that you have positioned the connector correctly in relation to the port.

Using the optical drive The SuperDrive in your MacBook supports standard 12 cm

(4.7 inch) discs. Irregularly shaped discs or discs smaller than 12 cm (4.7 inches) are not

supported and can become lodged in the drive.

Handling glass parts Your MacBook contains glass components, including the display

and trackpad. If they are damaged, don't use your MacBook until it has been repaired
