Something is extremely wrong with OSX. Its saying its executing kernels, but then not, and then doesn't emit any errors.
DM will wildly spin like that when kernels take zero time to execute. Problem is, the implementation MUST emit errors.
I so very much hate OSX.
Well, yeah, OSX is special. I am experiencing the same problem with the master of DiabloMiner. Strangely enough, a previous version (the one packaged as a Mac App) works nicely! Playing around a bit, I found the problem seems to have occurred between these git commits:
commit 354b53286af2e982e5c8aa030784a785ebc5032b

Switched to an unholy union of the current kernel and phatk. Dear Lord,
forgive me for I have sinned.
commit 2d0ed8523c17d011ae5e755936baab01becab171
Date: Fri Jun 24 01:22:45 2011 -0400
Move execution threads to 2 down from 3 since getwork can no longer
block execution threads
I branched from the "pre-phatk" checkout and patched all later non-kernel changes into it. Works great!
So the new kernel must at least be part of the issue. Figures, poclbm with phatk actually freezes my WindowServer, grrr.
But you're right, OSX really should do a better job at error reporting. With the way it behaves now, I have no idea how to fix this.
Oh well, praise git. I'll stick with my branch for now.
