When Apple finally added Night Shift to iOS there was a collective cheer from iPhone and iPad users. Night Shift changes the color temperature during the evening to lower the blue spectrum. This can be a help to some users in terms of making it easier to sleep.\nUnfortunately, Apple did not include Night Shift in macOS Sierra, and that has caused some irritation to Mac owners who expected the new feature to be available for the Mac as well as for iOS devices. It has also caused some to think that, once again, iOS gets a higher priority than macOS from Apple\u2019s developer teams.\nFortunately, there is a work around for Mac owners. f.lux is an app that you can download for your Mac for free, and it offers pretty much the same functionality as Night Shift in iOS.\nHere\u2019s the official description from the f.lux site:\n\nEver notice how people texting at night have that eerie blue glow?\nOr wake up ready to write down the Next Great Idea, and get blinded by your computer screen?\nDuring the day, computer screens look good\u2014they\u2019re designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn\u2019t be looking at the sun.\nf.lux\nf.lux fixes this: it makes the color of your computer\u2019s display adapt to the time of day, warm at night and like sunlight during the day.\nIt\u2019s even possible that you\u2019re staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.\nf.lux makes your computer screen look like the room you\u2019re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.\nTell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.\n\nI run f.lux on all of my Macs and it works beautifully. I never have to worry about my sleep being affected by day-time blue spectrum lighting. I\u2019ve been running f.lux for years and it\u2019s always worked very well for me.\nHopefully Apple will eventually get around to adding Night Shift to macOS, but until then I highly recommend that you download f.lux for your Mac. It might help you get much better sleep if you\u2019re someone that uses your Mac a lot at night.\n\nThis topic also came up in the Apple subreddit recently, and folks there weren\u2019t shy about sharing their opinions about it. So I\u2019ll leave you with this selection of comments about the lack of Night Shift in macOS Sierra:\n\nThrowaway359478: \u201cMac is always at least a major version behind in getting features. Heck, Siri was added to the phone 4 years ago and the Mac only just got it, in a cut down form.\u201d\nError_Loading: \u201cSeems obvious to me. It was much harder to do on the iPhone before they added it. Mac its very easy.\u201d\nSuchUserHasBeenTaken: \u201cOne thing I like about f.lux that Night Shift doesn\u2019t have is a third mode at around midnight that makes the screen a ton more warmer than it normally is.\u201d\nFrankPapageorgio: \u201cI just assume they hold back features so they have something for their next annual release.\u201d\nMarino4K: \u201cMaybe we\u2019ll see it in a 0.1 release.\u201d\nDydegu: \u201cIt might come in a dot release along the elusive new Macs.\u201d\nMore at Reddit\n\nDid you miss a post?
