Unfortunately, Wes is on vacation and he would be the person to ask as
he understands Macs and I do not.
Do you have an /AIPS/DATA/LOCALHOST_2 area? Try it with that (on the
assumption that you can undo it without trouble) rather than _1 which is
rather special. I suspect that there may be real problems with
creating/writing new files, but perhaps not.
In fact I would recommend that you make a whole new data area with only
a few files in it copied from one of your existing areas - add it to
$AIPS_ROOT/DA00/DADEVS.LIST and then try it with that area.
