14 DAY TRIAL // Magic Screen is a free Mac app that lets you mess around with your screen’s color, brightness, contrast, and other adjustments to achieve the perfect mood.
Similar in many ways to F.lux, Magic Screen comes with a much richer interface with loads of options and sliders and some cool screen lighting tweaks.
Depending on your state of mind or the lighting in your room, you can use Magic Screen to bring your Mac’s display up to par for a relaxing experience. Magic Screen is primarily designed to tweak your display colors for low-light conditions, but you can use it in any way you see fit.
You can download Magic Screen for free on the Mac App Store and install it on any system running OS X 10.6.6 or newer.
