I've tried several things. I had it set up and working in CS4 with FileMerge. When I went to CS6 I tried just copying the path from CS4 and using it, but it didn't work. And when I upgraded to Mountain Lion, the File Compare in CS4 stopped working also. Right now, in CS6 I just used the browse button and located FileMerge in my Applications directory. But that path doesn't work.
I have tried using /usr/bin/any3rdpartyShFile
I have tryed 3 different progrms but none load.
The file to compare from sevrer downloads from the server but the 3rd party file comapre program does not launch.
What has succesfully worked as a 3rdparty compare tool and what file path was used on MAC for cs6 dreamweaver ?
I prefer opensource (free) software but this feature is important to me and would pay if I knen it would really work.
BeyondCompare is Windows only.
On a Mac, install TextWrangler (free from barebones.com), and make sure you install it with the utilities. You can then set the path for the file comparison utility to /usr/local/bin/twdiff.
I've just tested it on Mountain Lion, and it works.
