Hi Volker, Marc, I can confirm, that opencl is not working any longer on Big Sur. Just in the days before the update to Big Sur I made some opencl benchmark tests (https://math.dartmouth.edu/~sarunas/darktable_bench.html <https://math.dartmouth.edu/~sarunas/darktable_bench.html>). Opencl worked fine that time. Now I have repeated the test (after upgrade to Big Sur) and I see, that opencl is not working at all.
0.047200 [opencl_init] could not find opencl runtime library '/System/Library/Frameworks/OpenCL.framework/Versions/Current/OpenCL' 0.047209 [opencl_init] no working opencl library found. Continue with opencl disabled 0.047213 [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system. 0.047216 [opencl_init] initial status of opencl enabled flag is OFF.
