GPU mining with Radeon 4850 on OSX 10.7
Is this at all possible? I can run GUIMiner with my GPU when I boot into Windows after installing AMD APP SDK, and get >50 Mhash/s, but When I run Phoenix on OSX, PyOpenCL crashes when I start mining. I'm using poclbm for the backend. Any suggestions? I have a strong feeling that the issue is with OpenCL. Some places say that ATI 4xxx chips require ATI Sream aka AMD APP SDK, but it does not appear to be available for OS X, is that because OS X has it built-in and my problem lies elsewhere, or am I out of luck?
Any help is much appreciated, Thanks!
