I sent this to Ron Reeder as well but maybe I can get my problem solved in the forum.
Couldn't open /Library/Printers/QTR/quadtone/Quad7800/UCmk-EpsEnhMatte-Sepiacopy.quad for writing: Permission denied
The other thing that is puzzling to me is when I follow your instructions to see if it is in the Library there is no QTR in the library only the Epson listing for the printers. I've deleted and re-downloaded Quadtone but it never shows up in the Library only Applications.
Reading your book Digital Negatives and building curves for QTR as you teach them. I duplicate the file and rename it plus make sure it is a .txt file. My problem is getting them installed. I put them in the proper printer profile and with the printer attached run the installation but they never show up. I've removed the printer from the print list before running the installation. Tried everything I can think of with no success. I've tried on both my R3000 and my 7800.
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.

Hope you can help thanks.
