Hi,
problem solved:
By using BOINC Manager 7.1.15 CPUs usage is normal (full 8 or 16 cores/threads used)
Not sure issues comes from Milkyway application or BOINC Manager?

Hi Team,
on Mac (OS-X 10.8.4) N-Body 1.18 (mt) is only using One CPU instead of 8 or 16 CPUs
(100% cpu usage in activity monitor, even task indicated with 17 thread on my Mac Pro)
So not all CPU power is used on multicore Macs

v0.31 works well.
Checkpointing and progress are OK.

Thanks Travis.

Hi,
It seems there is an issue with checkpointing on Mac OS X.
Percentage complete has been stuck at 0.0% since tasks are started (18 hours)
As my MacPro is running 12 h a day, WU is running since 2 days.
below copy of astronomy_checkpoint file of same WU before and after machine restart
