Hi-
I think if you update your AFNI binaries to the "10.12_local" from the "10.7_local" that you are using, your problem will be solved. To do this, run the following a terminal:
@update.afni.binaries -defaults -package macos_10.12_local
That will just: 1) update your AFNI version to the most recent, and 2) give you the new 10.12_local version in place of the 10.7_local (no paths or anything else need to be changed).
If that doesn't sort it out, then you might also have to do one of the suggested linking operations (written at the bottom of the afni_system_check.py output); that isn't bad to do, but it might not be necessary with the 10.12_local binaries.
