[Richard Koch]

Folks,

Ghostscript 9.26 was released on November 20, 2018. There is an install package for this distribution on my web site:

Older versions of Ghostscript are also available there. In case of trouble, install an older version on top of this latest version,

Thanks to Bruno Voisin for noticing this release and testing it. Bruno also provided the precise method used for this and earlier releases for the Mac to make them maximally effective with LaTeX.
