How to Use Night Shift in macOS Sierra

  • MORE

If you're having trouble sleeping, and wondering if constant exposure to your MacBook is to blame, you might want to download macOS Sierra 10.12.4. This update includes the Night Shift feature, seen previously in iOS, which is meant to help users get better rest at night.screen shot 2017 03 28 at 6.15.39 am

Just as with Night Shift on iOS and Night Light in Windows 10, Night Shift makes your Mac's display emit a warmer range of colors, removing blue light. This became a popular feature after studies showed that exposure to blue light wavelengths makes it harder to fall asleep by increasing attention and reaction times, as well as altering your mood.

    Being MacOS centered, I use Mail, Messages, Safari, iCloud, Preview, etc. but was disappointed being locked out of Night Shift. Mac users not wanting to use Sierra or having older Macs (like my mid 2010, iMac i7, 3GHz,16GB ram) are not limited to Apple's decision not to include Night Shift in previous OSX versions. I've used f.lux, a free application for some time blocking blue light before Apple released Night Shift. Fortunate for me, others build what Apple fails to do for its older customers these days.

    Now if we can get them to license MacOS on better hardware than they have been releasing lately.....
