Mac users interested in Crowbarkc dictionary generally download:
crowbarKC is a dictionary attack tool for Mac keychain files. It is completely free, so enjoy. Be sure to read the included PDF readme file. I address an issue if you use strings to pull out a dictionary from a disc image. Some control characters need to be scrubbed else it will crash crowbarKC. Give it a shot if you need to recover a password for a Mac keychain.
