Hello,
behind the 10.7.3 update the Boinc Client V.7.0.15 won´t reconice OpenCL of my NVIDIA Gts450.
I have to rollback the GeForceGLDriver.bundle to 10.7.2
NVIDIA GPU 0: GeForce GTS 450 (driver version 4.1.28, CUDA version 4.10, compute capability 2.1, 1024MB, 718MB available, 653 GFLOPS peak)
OpenCL: NVIDIA GPU 0: GeForce GTS 450 (driver version CLH 1.0, device version OpenCL 1.1, 1024MB, 718MB available)

The Install Pkg. of V. 7 won´t work in 10.7.3 too

I forwarded the info to the developer, he answered me:

Please note that there are various reports of corrupted 10.7.3 *delta* updates. I recommend you download and install the 10.7.3 *combo* update again (right onto your delta-updated 10.7.3 system) just to make sure.
Get the combo update here:

Also, I originally installed CUDA 4.1.28 at the same time as the OS 10.7.3 update, and BOINC crashed on startup. I then went back to NVIDIA's web site and downloaded and installed CUDA Driver 4.1.25. BOINC once again ran properly. I finally re-installed CUDA Driver 4.1.28 and BOINC ran normally. So there may be some significance to the sequence of updates.

hello, i used the final combo update 10.7.3 (11D50) and tried (11D50b) too.
behind used the latestest cudadrivers_4.1.28_macos (and 4.1.29), cudatoolkit_4.1.28_macos and sdk.

but Boinc 7.0.15 (and before) won´t find OpenCL with 10.7.3 GeForceGLDriver.bundle 7.18.11

but with GeForceGLDriver.bundle 7.12.9 from 10.7.2:
NVIDIA GPU 0: GeForce GTS 450 (driver version 4.1.29, CUDA version 4.10, compute capability 2.1, 1024MB, 889MB available, 653 GFLOPS peak)
OpenCL: NVIDIA GPU 0: GeForce GTS 450 (driver version CLH 1.0, device version OpenCL 1.1, 1024MB, 889MB available)

The GTS450 shows with Collatz3.06 openCL slot 0 and with BRBCuda32OSX slot 1 is this right ?

could it be that 10.7.3 has a different driver as version CLH 1.0 and won´t be recognized ?

ps: luxmark opencl benchmark find my gts450 with the 10.7.3 driverbundle
