“There must be a way to use DPS v1 on Mac OS 10.6 now fully.”
There is not. I believe that previously DPS version 1.0.6 was working on MacOs 10.6. However we have ended support for version 1.x and it is no longer possible to activate that version of the program. It might work for a few days, but then it will time out and stop functioning. Also, it is not possible to download any profiles for version 1.x since the server handling that functionality is no longer online.
