Hey Leander! Good to hear you are still using darktable.
* "I'll spend three hours getting things lined up in real life instead
of spending five minutes in post."
I also prefer to get things right in camera, but that isn’t always an
option.
* "Leaving aside OpenCL, I think latest dt (2.0.5) uses a GTK version
which doesn't work well with Mac (bad perfomance and usability
problems)."
I think this is another big issue for me. This is why drop down menus
(new instance, duplicate instance, etc.) hang or don’t work at all.
Let me know if you have any luck with gfxCarStatus app. I’ll try
reverting to 2.0.4 and see if that helps.

Hi, I have a similar problem with my old canon eos-300d in dt. The higher Iso
images suffer a green cast. The problem is caused by the raw black levels being
incorrect. For some reason dt sets the levels to high. May be your nikon
problem is related. Try checking the raw black levels for the green images in
dt and use Image-ExifTool to check what the values should be.

Sounds like we have basically the same machine. I have the issue with
the green photos too (Rafa García was just telling me about it off
list). Our MBP model does have the dedicated Radeon M370X card but it
seems Darktable doesn't cause the OS to automatically switch, at least
on mine.
On that tangent I also just discovered that the person who writes
gfxCarStatus has updated their application to work with newer versions
of OS X. It's a little menubar widget that lets you override the OS and
manually force the dedicated card into service. I'm going to give that a
go and see if forcing Darktable to use the Radeon helps any. You may
want to give it a shot too: https://gfx.io/
Just a quick update, I tried version 2.0.4 while forcing the Radeon M370X on
and the green image problem persisted. Darktable also seemed to run slower
than with OpenCL off but it’s late I didn’t do any extensive testing. I did
notice that only some my Nikon RAWs were turning green this time. The Fuji
RAF files seemed fine. Could be nothing. I’ll look at it more in the
morning.
