Subject: OS X Macbook problems trying to use GPU
I have tried both building both macosx-x86-64-opencl and macosx-x86-64-cuda builds of JtR to no avail. I did this with the latest 'bleeding jumbo' code base
Both versions build but they each have a different problem.
The macosx-x86-64-opencl just hangs cold as soon as I try to use an '-opencl' format (e.g. --forma=wpapsk-opencl). The system stops responding completely. I have to power the machine down using the power button.
The macosx-x86-64-cuda build tells me I don't have a CUDA compatible device.
Has anyone successfully built a GPU-enabled JtR on a system like this? I don't particularly care whether it's CUDA or OpenCL, I just would like to take advantage of my GPU if possible.
