Enjoy the audio and tactile feedback of soft keys on the compact 4 Pro Mechanical Keyboard for Mac from Das Keyboard. The full-size keyboard features all the Mac-specific keys you are used to, as well as a convenient, large volume knob. The extra-long 6.5' cord plugs into a USB port on your computer, which also provides power for the two USB 3.0 ports on the keyboard. Use this USB hub to transfer files, sync your phone, and attach peripherals. An unexpectedly handy feature is the footbar that raises the keyboard, which is magnetically detachable and scaled on both sides so it can double as a 16" ruler when not in use. A designated sleep key on the 4 Pro puts your computer to sleep, helping you save energy and get back up and running faster than if you had to shut down and restart. Sturdy construction will keep your 4 Pro running for a long time.
