Is caffeinate broken in macOS Sierra?

I'm running a late 2016 MBP with current level of macOS Sierra. While in clam shell mode and connected to power I'm not able to prevent the mac from going to sleep via the caffienate command. I've tried to use various different options: -i or -s. I leave the terminal window up and do not fork the task to background.

I've also tried various utilities from the Mac App store, most recently one called Caffeine. None of the these seem to work either.

My energy saver settings are:

Most of the time I want the behavior as detailed in the image. However, there are times I want it remain awake without having to modify these settings.

Is anyone else having this problem?

Don't know if Caffeine has been updated recently. It went dark for a while and I ended up switching to Amphetamine, which has done the job nicely.

Caffeine hasn't worked properly since maybe Yosemite and doesn't seem to be supported any more.

I've been using KeepingMeAwake, which is still under active development.

Ok. I'll take a look at Amphetamine. No one using the built in osx commandline though?

No, because they are not unique to caffeinated. The "&" in Terminal simply means that another command is to come and you can use man nohup to read about that command.

Caffeine is an older app from Lighthead software that the OP mentioned in the first posting.

caffeinated was an autocorrect error that I can no longer edit.

The one most relevant seems to be -S and it does not work.

Perhaps it will be fixed in 10.12.4?

I used the suggested "caffeinate &"and it works. Only thing I could find to use on Sierra. Very frustrating to discover this problem when I'd been using caffeinate with no problem on Yosemite.
