range for color scaling

I’m using mac OS 10.12.2.
I cannot adjust the range for color scaling in overlay window,
AFNI also crashes when I close one of axial, sagittal or coronal windows (push red x button).
I installed lastest version, macosx_10.7_Intel_64.

You should have the “local” version installed for Mac, as described here:
As part of following all those instructions, please make sure you have the DYLD_LIBRARY_PATH set (it’s explained there).

You can check the status of your installation with Rick’s handy “afni_system_check.py -check_all” tool (also described in those pages).
