Thanks giladteller for your reply.
First, I have found a directory called Cities in Motion in Documents, that it has 4 files: control.keys; log_metro.txt; settings.script; state.gs.
Second, I have found a directory called Cities in Motion in Library, Application Support, where this directory has the maps and saves directories with the same 4 files that the first directory.
And finally, I have found a directory called Cities in Motion in Libray, Application Support, Steam, SteamApps, common, where it show the app and I do click the secondary mouse and show the properties and it show the tipic structure of one app in mac.
Any suggestions?
Thanks.
