Meld For Mac

There are alternative solutions to installing meld on OS X: Use a different package manager, like Fink, which is mentioned in meld's installation manual, or MacPorts, mentioned in the issue in Homebrew's issue tracker. You can probably also compile from source, but need to get the dependencies yourself. With Meld for Linux, you can compare two or three files and edit them in place. You can compare two or three folders and launch file comparisons. There are many alternatives to Meld for Mac if you are looking to replace it. The most popular Mac alternative is Beyond Compare. It's not free, so if you're looking for a free alternative, you could try KDiff3 or FileMerge. If that doesn't suit you, our users have ranked 40 alternatives to Meld and many of them are available for Mac so hopefully you can find a suitable replacement. If you start Meld from the command line, you can tell it what to do when it starts. For a two- or three-way file comparison, start Meld with meld file1 file2 or meld file1 file2 file3 respectively.

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 for creating Meld.
  • To the Gnome project
  • 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.


  • Get rid of the Meld wrapper shell script (this should get rid of all the wrappers needed to run Meld from the terminal)
  • Support Meld localizations (currently only English works)

Suggestions / Issues

I'm not currently accepting donations for the development of this fork. I just missed a proper implementation of Meld on Mac so I thought of creating this fork. If you want to donate, please donate to the original Meld project.

What is Meld?

Meld is a visual diff and merge tool targeted at developers. Meld helps you compare files, directories, and version controlled projects. It provides two- and three-way comparison of both files and directories, and has support for many popular version control systems.

Meld helps you review code changes and understand patches. It might even help you to figure out what is going on in that merge you keep avoiding.
