15 Things You Didn't Know You Could Do With Your Macbook

15. Inverting Colours

Used by people that have difficulty seeing text on screen - or by kids that want their Apple devices to look cool and weird - inverting the colours on a screen is an important feature in any operating system to make sure that it can be used by as many people as possible. Unlike some OSes that would need users go through layers of system preferences, your MacBook as a quick shortcut to invert your screen. Holding down CMD + CTRL + ALT + 8 will immediately invert every colour, making reading books or long forum posts much easier on the eyes.
