savestate

I want to access the file that is created by SaveState manually (not from the app) to check some data saved by the game. Where do I find that file on Mac?

When I use SaveState() my App crashes. After a while, the message "APPNAMEHERE isn't responding. Do you want to close it? <Wait> <OK>" appears. Fun thing is: the state is saved correctly anyway. And can be loaded without any trouble. Does anyone know what could cause this? Or how to debug such...
