Does darktable actually *use* the OpenCL? Best way to check that is starting dt with >darktable -d opencl (manual, section 10.2.5). Also, on MacOS, compiling the required opencl kernels can fail partway through the process. As the kernels that were compiled succesfully are retained, the (only) solution to this seems to be restarting darktable several times. Once all the kernels are succesfully compiled, opencl should work. If this is the case, you should get compiler error messages in the darktable output from darktable -d opencl.
