The mojave upgrade from 10.14.5 to 10.14.6 broke my old VLC install (already fixed by upgrading the VLC install) and I think it has also broken my Meld 3.19.2.osx6 build provided through Homebrew.

I don't find any build more recent than mine.

What's the different thought way to meld in macOS? (What's the alternative free (and gratis) program?)

Have you seen this fork? https://yousseb.github.io/meld/ Maybe that will work???

As for alternatives there is FileMerge that comes with Xcode. To open it from the terminal, run opendiff.

  • The fork, I'd seen it! I think it's staying in the same level as the brew build. opendiff didn't helped me much (I didn't know this before you) because it's a horrible UX compared to Meld (so you don't get the accept (yet)), but you definitely get the upvote. :)

    You may want to take a look at this... stackoverflow.com/questions/229142/…. This has a whole list of different alternative. I haven't used any but you might find what you are looking for. Commented Aug 16, 2019 at 21:59

    I think I turned to Meld years ago because of being much more pleasant than KDiff, but's definitely worth trying KDiff back!

    So KDiff just works, but is still really really rough compared to Meld. :/

I'm quite happy with DiffMerge, but I haven't tested it in Mojave.

DiffMerge comes with a command-line script that opens the GUI from the terminal, which is handy.

  • I had missed this one, and tried it now. Looks really really nice, I'm going to accept this answer, because I think that even KDiff is very nice, this might be the closest to the Meld niceness.
