Just installed DAZ Studio 4.9 (64bit) on my Mac with OSX 10.8.5. It loaded fine, but when DAZ Studio opens I get error message "A valid PostgreSQL CMS connection could not be established." I checked and installer did create "DAZStudio4 64-bit" folder and "PostgreSQL CMS" folder in application folder and "My DAZ 3D Library" in Users/Shared.
This is a Mac, so there is no anti-virus or firewall software. Any ideas what what might be causing the problem?
