This question came from our site for professional and enthusiast programmers.

It is part of the Mac OSX Developer tools which shuold have been included on the CD which came with your Mac. I believe you can also download it from the Apple Developers Site after registration.

Once it is installed you'll find it in /usr/bin/opendiff

opendiff is a command line tool. So, you should be able to open a terminal, then type opendiff -h. If it's installed, you should see a help file. If not, you'll get a 'opendiff: command not found' error message. I think opendiff is part of Mac OS X - I don't know that you can get it outside that.

If you're not wedded to some specific feature of opendiff, maybe GNU 'diff' will serve your needs? – dublev Jun 18 '10 at 19:56
