Hi Lukas
sorry, I'm out of my depth on the mac. Perhaps Zeke knows what's going on?
Does OpenMP have to be enabled somehow?

Hi Bruce!
I just run: recon-all -s ernie2 -autorecon2 -openmp 4
mri_ca_register uses 100.9% CPU at most ...
Any idea? Should I try to recompile FS for the current MacOS release? If
so, do I have to take care on special librariwa in order to enable the
openmp option?
Best wishes,
Lukas
