That's what I thought originally, I think...

I remember the discussions of it but was never affected by it. However,
googling discovered instructions for clearing it.

At least, I removed /Library/Caches/com.apple.ATS, rebooted,
re-disabled bunches of fonts in Font Book and re-resolved duplicates. I
then re-typeset the file in TeXShop. I forgot to delete the old output,
so I did that and typeset again.

Still the same weirdness.

I also remembered that the file ought not to have typeset with the
usual XeLaTeX engine because I used External Location but it didn't
complain and still typesets the line which specifies the file location
correctly (bar missing characters) but not the line where the location
is not specified. (Claim that it shouldn't work is based on the
fontspec documentation which states this works only with xdvipdfmx and
that this isn't the default on OS X.)

So now I have some things working which shouldn't & some things not
working which should?!

Problems you never knew you had always turn out to be especially
