I just got a new computer so decided to start crunching again after not running for a while. This is the machine:

I'm seeing a lot more inconclusive results than I would expect so far. When they get sent out again, we'll see what the third wingman has to say, but I'm concerned that something is going wrong on my end with this many. The CPU is running pretty hot, though I've restricted it to use only 75% of the cores and 75% of the CPU time (so with HT this results in 6 threads running, plus the OpenCL app). All of the inconclusive WUs were on the OpenCL GPU. Anything to be concerned about?

If you were on Windows, I'd tell you to change the Intel GPU driver as a couple of older ones fare better than the latest one. On OS X though... not sure.

Can you do a search for 10.18.10.3621 for Intel HD drivers for your version of OS X?

I don't think there's any way to get updated Intel graphics drivers on OS X other than what Apple provides, sadly. Is that driver version known to cause problems on Windows?

No, that driver version, or perhaps the 15.33.37.4242 version are considered sturdy on Windows and preferred over the version the OS installs. If you have that possibility, that is. I suspect you do not with OS X.
