this version always asks me for permission to access the files every time it compares a folder Generally, once permission is given, it should not be asked every time (over and over again)

Thanks for build @matthiasdiener. Build works nice also on Mac M2 . Thanks a lot. I would appreciate to get this official on Meld. I had just to uncheck "use system font settings" as text was not readable.

This build works great on my M2 machine! Just had to run xattr -rc /Applications/Meld.app to shut up Gatekeeper. ^u^

The dmg seems to depend on some libraries from homebrew. It seems to die because it cannot find libpng on a machine without homebrew:

Echoing what @fadeopolis posted, though in my case homebrew IS installed, but the paths are not standard on my system due to having an installation that I've just kept nursing since my user was on an x86_64 CPU...

$ ll /usr/local/opt/libpng*
lrwxr-xr-x  1 x  x  23 Nov 20 10:53 /usr/local/opt/libpng@ -> ../Cellar/libpng/1.6.40

$ ll /opt/homebrew/opt     
total 0
drwxrwxr-x   2 x  x    64 Jan  6  2022 ./
drwxr-xr-x  32 x  x  1024 Jan  6  2022 ../

Edit: Re-installing homebrew and then installing brew install pango brotli makes it work. Now I have the care and feeding of two homebrew installations: one arm64 brew and one x86_64, aliased as ibrew. Fun times :P

This solution work for me! And, for what I see, to a lot of other people, when do you integrate it on brew package manager? I love MELD! ❤️

[jerryOnlyZRJ]

It doesn't work on my M3 machine.I need to find an alternative solution.

[rsireland]

It does not work on my MacBookPro running Sonoma.

Seems like there's a path problem while importing libraries. It looks for libpng16.16.dylib and libbrotlidec.1.dylib in the homebrew path, even when they're included in the package.

It looks for them in /opt/homebrew/opt/libpng/lib/libpng16.16.dylib and /opt/homebrew/opt/brotli/lib/libbrotlidec.1.dylib but they're located in ./Meld.app/Contents/Frameworks/.

So I did a couple of soft links and it started working:

sudo mkdir -p /opt/homebrew/opt/libpng/lib/
sudo ln -s /YOURPATH/Meld.app/Contents/Frameworks/libpng16.16.dylib /opt/homebrew/opt/libpng/lib/
sudo mkdir -p /opt/homebrew/opt/brotli/lib/
sudo ln -s /YOURPATH/Meld.app/Contents/Frameworks/libbrotlidec.1.dylib /opt/homebrew/opt/brotli/lib/

Substitute YOURPATH for the path to Meld location.

Funciona en M1 con Sonoma 14.1.2 (23B92)

Muchas gracias.

Update: The best solution at the moment is described in a gist linked from https://github.com/yousseb/meld/issues/151#issuecomment-1849188969. It involves installing a prerelease (not the homebrew nor the Nix version) and running a couple of commands to patch it.

I wanted to share a couple of imperfect workarounds, adding on to the workaround in https://github.com/yousseb/meld/pull/148#issuecomment-1800158447 (that I haven't tried).

The Nix meld package does seem to run on Mac OS Sonoma on Apple Silicon. It does not run perfectly; there are some graphical glitches, but seems usable. I posted a few more instructions at https://gitlab.gnome.org/GNOME/meld/-/issues/804#note_1953154.

As another option, you can run XQuartz and lima, and install the Linux version of meld inside the VM (sudo apt install meld). Make sure to add the following to the lima YAML config file:

ssh:
  forwardX11: true

I think I got it to work, if a bit slowly. The QEMU emulation is better for graphical acceleration. I'm not sure whether there are additional necessary steps I forgot; I might update this post if I remember something.

This version works successfully for me on my M1 Mac. The version available from brew, as well as the most recent version available for download on this repo only showed the title bar for me.

what do I have to do with this message?

I've seen similar-looking errors when I used the system-installed python on Mac OS instead of the homebrew python.

Any update on this? Would be super useful to have an M1 release! And also bring it into line with the upstream GNOME version.
