Using the optical drive The SuperDrive in your MacBook Pro 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 Pro contains glass components, including the 
display and trackpad. If they are damaged, don’t use your MacBook Pro until it has been 
repaired by an Apple Authorized Service Provider.

months, discharge the battery to approximately 50 percent. To maintain the capacity of 
the battery, recharge the battery to 50 percent every six months or so.
