Hi John,

Where did you put your custom PGP file?

The default one is in "~/Library/Application Support/Autodesk/roaming/AutoCAD 2015/R20.0/enu/Support" folder, as usual.

If you want your custom PGP file to be loaded instead of the default, you need to put it to the folder which is on the top of "Support files search path" list in Application tab of AutoCAD:
