Broken with new models?

[QuentinRoy]

The package does not work on my laptop (MacBook Pro 13-inch, 2017 on macOS High Sierra). ambient() always returns 0.

It seems I am not the only one, c.f. Exelord/dark-mode#3.

A possible (though surprising) lead might be an incompatibility with MacBooks with a touchbar.

Indeed it seems to be broken on the touchbar series of mac.
I'll take a look shortly.

just let me know, if I can help, looks like they are dropped support of AppleLMUController
Probably now it's inside FaceTime Camera ioreg -f -b -r -c AppleBacklightDisplay

And looks like Apple not provide any API for getting light sensor data now

All ideas are welcome 👍
After a quick search, it looks like the AppleAmbientDisplayAgent falls back to HID notifications when AppleLMUController can't be found.
That seems to be yet another private API, however.
