Screenshots are discouraged here - it's best to copy-paste textual info right into messages - and besides many image files are automatically stripped from messages because some people tend to have images as part of their signatures.

As an exception to the no-screenshots preference here, I took a look at your screenshot (that didn't make it through to other list members, but was available to us list moderators). In there, you appear to have the full pathname listed after "Where:". You need to do something like this: 1. Download and extract e.g. john-188.8.131.52-jumbo-macosx_sse4.zip (already done?) 2. Take note of where you extracted it to. 3. Open a Terminal. 4. Type a "cd" command with that pathname, putting the pathname it into apostrophes because otherwise you'll run into issues with its embedded whitespace characters. The command might be: cd '/Macintosh HD/Users/smorg5127/Documents/Research/Research' Hopefully, it's correct and will succeed. If not, split it into several "cd" commands - one directory at a time - to see where it fails. Omit the leading "/" before directory names on commands other than the first. 5. Once you're in the correct directory, type: /path/to/john-184.108.40.206-jumbo-macosx_sse2/run/dmg2john 'GWS Research.dmg' > mydmg.txt You'd need to replace the "/path/to" with the actual pathname you noted in step 2. If successful, this will produce file called mydmg.txt near your .dmg file. You can take check its size with: ls -l mydmg.txt or/and use any file manager app to access it. 6. Try actually cracking the password with: /path/to/john-220.127.116.11-jumbo-macosx_sse2/run/john mydmg.txt Alternatively to the above, you can "cd" to the directory with dmg2john and then use simply "./dmg2john" (no full pathname to it anymore, just a dot in its place) and specify the full pathname to your .dmg file as dmg2john's parameter. I hope this helps. Alexander
