Turning on your Mac mini Never turn on your Mac mini unless all of its internal and
external parts are in place. Operating the computer when parts are missing may be
dangerous and may damage your computer.
Carrying your Mac mini Before you lift or reposition your Mac mini, shut it down and
disconnect all cables and cords connected to it. If you carry your Mac mini 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.
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 Mac mini supports standard 12 cm
(4.7 inch) discs. Irregularly shaped discs or discs smaller than 12 cm (4.7 inches) are
not supported.
Storing your Mac mini If you are going to store your Mac mini for an extended period
of time, keep it in a cool location (ideally, 71° F or 22° C).
Cleaning your Mac mini When cleaning the outside of your Mac mini and its
components, first shut down your Mac mini and unplug the power adapter. Then use a
damp, soft, lint-free cloth to clean the computer’s exterior. Avoid getting moisture in
any openings. Do not spray liquid directly on the computer. Do not use aerosol sprays,
solvents, or abrasives that might damage the finish.
