I get this during the Terminal installation process but I get it on all of the profiles. I made a copy of one to show you my issue. Couldn't open /Library/Printers/QTR/quadtone/Quad7800/UCmk-EpsEnhMatte-Sepiacopy.quad for writing: Permission denied Make sure you are using the most recent version of QTR, including the profiles. El Capitan and later versions of OS X prevent you from writing to many system areas that used to be available. I think the latest QTR update resolves the issue. At any rate, there was considerable discussion on this group about the problem a while back. Myron __
