Title says it all. I just installed the Apple OSX 10.8.5 supplementary update, and now the NVidia web driver doesn't work. See link here. The good news is that the OSX driver for my GTX 580 / GT 120 combo GPU setup allows OpenCL, since both cards (and the CPU) report OpenCL 1.2. Finally I can run LuxMark and OpenCL_OceanWave benchmarks!
