I had a Macbook pro retina(late 2013, intel iris graphic cards). I did some tests with darktable-cli and OpenCL. I saw performance improvements (some modules took less than half of the time). But the green output did it useless.
I don't remember were I read it but previous intel graphic cards were working right in Mac. 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). Regards PS: I had to downgrade to 2.0.4 to use happily dt 2016-08-17 19:10 GMT+02:00 Brandt, Riley <[email protected]>: > Hi Leander, > > I am also experiencing disappointing performance in darktable on a new > Macbook Pro.
