I would love to try it because I recenlty baught a radio that I got attached to my iMac, but the installer has severe problems with its post-instlll script. I first downloaded it from download.com and then downloaded it again from the ambrosia site.
If i unpack it using stuffit deluxe it says: postinstall script allready exists in this location what do you want to do with it? Pressing cancel and running the app results in an installer that opens but does nothing and shows nothing.
Simply expanding the .sit archive with expander results in an error when opening it and the errormessage is: the postinstall script was either not readable or not executable.
