Paid, but it has the best looking UI of any diff tool I've seen for Mac. Kaleidoscope also does a very nice job of breaking down which words differ inside lines and nicely wrap long file formats like html so the atomic changes are more graphically evident. Compared to line based diff tools, this is a nice step up.

Why Meld for Mac/OSX and not Macports/Homebrew

Top reasons behind using this fork over Macports or Homebrew builds:

  • Retina support (check the screenshot!)
  • Latest 3.x series
  • No hassle install (drag/drop like any other app)
  • Integrates with OSX menu
  • Supports standard OSX shortcuts (cmd-c/cmd-v instead of ctrl) (Merged to upstream)
  • Note: Homebrew now installs Meld for OSX


Special Thanks

  • To Kai Willadsen http://meldmerge.org/ for creating Meld.
  • To the Gnome project https://www.gnome.org/
  • To Alex Kras whose web page (How To Run Meld on Mac OS X Yosemite Without Homebrew, MacPorts, or Think) served as my reference for tracking Meld for OSX usage and issues when I had absolutely no time to maintain this.
