Have you ever been running a few days behind where you thought you should be on the calendar? Normally, I like a Friday Freebie but completely missed it last week thanks to an embedded hair regarding how powerful a Mac we need these days. It’s been awhile since I had a really good Friday Freebie that I could easily recommend to any Mac user. More power is better, yes, but there is a price tag limit. So, I missed the Friday Freebie experience. Sorry. My bad.
Allow me to start the week with a nifty utility called f.lux, a tool which alters the color of your Mac’s screen based upon the time of the day. Say what what? Why? Remarkably, the light from the sun actually changes based upon the time of day, and that often changes the light wherever we’re using our Macs (home, office, school, on the road) which then changes how the Mac’s screen is viewed. How our eyes react to light depends upon where we are, what light is around us, the time of day, and what’s on the Mac’s screen. And they’re not all in sync.
f.lux makes the Mac’s screen match the time of the day. Think warmer at night when light from the screen can be glaring, but more like sunlight during the day.
Open f.lux, adjust the simple setting, and watch the screen’s color hue change as the day wears on. The first thing that happens, though. is f.lux checking your current location. Apparently, that matters to sunlight.
But don’t think that f.lux is a simple one-trick pony. If you need to disable the default settings all you need is a click to the Options menu. Also built in to f.lux is an option that answers the question that many of us who work into the late hours of night ask, “How much sleep will I get if I go to sleep now?”
Not every Mac user prefers the default settings for color in mac OS, so Apple provided a few options. f.lux gives you more so you can expand daylight which is good for those who love the onscreen warmth of daylight. That’s also in the Options menu.
f.lux also lets you control what a day is and when it begins, rather than just following the sunrise and sunset for your particular location. It even handles weekends where you might want to sleep a little longer.
The Mac App Store has two or three such screen-modifying utilities, usually priced at a few dollars. Apple builds into iOS 10 a function called Night Shift which does something similar, too, and according to a schedule. If you’re a Mac user who uses your Mac at all hours– morning, daylight, afternoon, evening or even late at night– then you’ll appreciate what f.lux does for free. Highly recommended and you cannot beat the price. There’s also a version for Windows, Linux, Android, and iOS (which requires a jailbroken iPhone or iPad, though).
