known issue with gpu performance tests on macs. If that doesn’t give proper results (thats usually the case ) opencl isn’t activated.
You can activate it yourself in ./config/darktable/darktblerc :
see: darktable user manual - memory & performance tuning
find the line: cldevice_v5_… and switch parameter h from 1 to 0
