In 2012 I wrote a document, for Mac users, that noted that changes in Shell Escape (not relevant here) and also in installing fonts that noted the difference between installing in TEXMFLOCAL and TEXMFHOME and updmap-sys and updmap. It is something that has come up too regularly in the Mac community. And here we are in 2017 still living with the same, difficult to anallise, problems
