Hi Partha.
My macbook pro is recent (< 6 months) and I use the very last OS (High 
Sierra 10.13.4), but nevertheless it works with 1 thread. I have tried 2 
and 4 threads (the default), with or without OpenCL, and it crashes.

Thanks for all (especially your builds). Maybe it is a bug to address 
with high priority. 2.8 was ok in multithread.
