This is the unfortunate truth. I'm still using El Capitan with my Mid 2011 Imac, even though Sierra was introduced just five years after the machine was built (September 2016). I haven't been bothered to run the update.

Almost none of the new features of Sierra work on on a Mid 2011 machine. At first I figured that they had to throw us a bone with Night Shift, as there was no technical reason to deny it. However, apparently they're not going support a five year-old machine with OS features anymore. Having used Imacs for a long time, this is the fastest I've seen them try to make a particular machine obsolete in the post PPC era.
Weird, Sierra works fantastically on my mid 2010 cMP. (Haven't tried the night shift update).
Either way, obsolescence is an ever-changing idea. If I was stuck on my cMP for 3 more years I think I'd be fine (maybe I'll flash a new graphics card, or put 64gb of ram in, but that's all). So honestly running El Capitan on a 2011 iMac doesn't sound too bad to me, especially when many people I know refuse to update to Windows 10 and still Run 7.
 
Did you try the steps listed here?

Yes and made the 06 to 05 change through Xcode.

Night Shift "installed" completely fine the first time and after one restart. However, for some reason it is not 100% reliably present after another restart or when switching users/accounts. Change was made to the system library (not user library) and this is a 100% authentic mid-2012 5,1 MacPro - not an upgraded 4,1 or 3,1 or a purchase from 2010.

May change that 05 to a 04 when I get a chance to see if it makes a difference.

Primary monitor is a 27" Apple Cinema LED.

A late 2011 Imac was four and 1/2 years old when Sierra was released, and, while I understand them not providing support for any of the new features, denying us Night Shift is just greedy. There is no technical reason that it shouldn't be supported. Indeed, people have already written hacks to force it to work with these machines.

I'm glad that Sierra works well on your 2010 machine. I simply went through the long list of new features and, as none except Siri were supported, I decided against the update. I may try to hack Night Shift for my machine at some point, but I'm sure that Apple will simply disable that loophole with the next update.
 
Its a effin joke that it doesn't work on my Mac Minis 2011 and 2012 with external monitors.. so I caved and got F Lux. I waited a long time for Night Shift mode by Apple.. disappointed. I am not comfortable with coding/terminal and stuff.

I can agree with this, there's zero technical reason nightshift should be denied. Dunno if it's outright greed or Apple simply saying "**** it, we aren't testing this on old Macs, so we'll just disable the feature so there's no problems", ****** behavior either way.

There's always f.lux anyway.

It works with the external monitor on my 2012 Mini (can it be anything other than external on a Mini??)

And.. Im probably going to disable it again. All it does is make my monitor look about 10 years older than it actually is. I'll give it some more time to see if I can get used to it, but so far, it's crap.
 
It doesn't give me an option in the Display menus for Night Shift. I have a mac mini (2014) connected to a Samsung TV. Are only 4 external displays supported for night shift, really? Trash update.

Weird.. I didn't even notice those displays in the requirements.. I don't own any of them, just an inexpensive generic Samsung 23" LCD monitor, and yet, it works!?
Still, you are not missing anything. It just makes your monitor look like its had a multitude of smokers sat in front of it for years. Really.

Well its a TV (top end) connected to my 2012.. but the Night Shift option doesn't come up, seems like its restricted to pure computer monitors.. f.lux works just fine with my TV.
 
I've been using night mode on my phone and iPad now for a few months and I do think it makes a difference.
About a year ago I changed all my bedroom lights to have a really warm temperature, but most importantly I bought an LED reading lamp with a remote control to change the colour. Since I started using it I found myself feeling more tired before bed and I'm now getting an uninterupted 8 hours where previously I'd get 4-5 before entering restless sleep. I think this "warmer lights before bed" is going to be found very important in time.

Hmm, so if I understand correctly, night shift is supposed to make the screen more warm hence reducing blue light? I guess this is similar to those "glasses" that promotes to filter blue light from LCD screens?

Yup. Blue light is close to sunlight in terms of temperature, and it's believed that the body tries to stay awake while exposed to it. Warmer lights promote restfulness. Or something. Either way I'm slightly freaked out over how effective it is.

I've been using F.lux for 3 years, tried Night Sift...
It feels like a lazy clone, no optimisations for different locations (I live in the north so apples implementation means it will probably never turn off in the winter). The range of "orangeness" is very limited in comparison to f.lux.
Also lacking option for automatically disabling in graphic centric apps, video players, Photoshop etc...
I'm back in F.lux now. Probably biased, but hey I'm happy ;).
