From Apple: “Besides changing the look and feel of your Mac, you can also let your Mac know how you prefer to work by using System Preferences. System Preferences controls system-wide settings (“global” settings), and … lets you adjust things like your screen resolution, keyboard control, mouse control, sound, printer settings, sharing settings, accounts, and more.” (While the Club has a few Macs, please bring your own Mac laptop if you have one.)

Platform: Mac.
