Hi, Selene-
We no longer update the 10.7 binaries for Mac-- therefore, it is just one somewhat old version of it that exists.
You can still just migrate to the 10.12_local binaries, which I presume should be fine for your Mac (I think from 10.11 and upwards they actually work, if I recall, but I may be misremembering... definitely from 10.12 upwards):
@update.afni.binaries -defaults -package macos_10.12_local -do_extras
--pt
