3.21.0 (r4) Sonoma (pre-release) won't open on M1/Sonoma

[TonyFarAAO]

Hi,
I have an M1 mac updated to Sonoma 14.1.2. I tried installing the latest version. The App won't open - reporting "You can’t open the application “Meld.app” because this application is not supported on this Mac."

Rosetta 2 is installed and other intel 64bit software does run ok.

I tried running the program directly by executing "/Applications/Meld.app/Contents/MacOS/Meld" in a terminal window (which works for me in the previous version). With the latest version I get "Meld.app” cannot be opened because the developer cannot be verified."

This later message is normally dealt with by opening the App via the control-click menu, but the first problem stops that working.

Something about the packaging might be wrong!

I can confirm the same issue on Sonoma 14.2 Beta on an M2.

[hardyoyo]

Can confirm as well, M2 on Sonoma

Systems Settings --> Privacy and security --> at the bottom will show the latest failed to open app (meld).
you can now choose to open it.

I'm on Sonoma 14.1.1, regular intel old mac. Meld opens for a second then crashes.
It might be a differnt thing, and I can open a different bug in that case, but it seemed the above users didn't do ^ first.
The meld app receives a SIGSEGV according to the stack trace

Please do not assume that we didn't do basic troubleshooting. I did, this app doesn't open on Apple Silicon. I have found an alternative app that works.

Good to hear

It wasnt clear from the original issue.

It would be interesting to know if M1 /M2 chip Mac's also generate the SIGSEGV, in which case the issue is uniform and not specific to chip-setup

[TonyFarAAO]

On my m1, if staring by double clocking, the console shows

error	19:22:59.451145+1100	Finder	LAUNCH:Application cannot be launched because its unsupported bit is set, org.gnome.meld node=<private> status=-10661

A dramatic change today when I tried to launch it from the terminal. Instead of what I got above, I got this (more useful) mess:

See the py2app website for debugging launch issues

Notice the reference to "/usr/local/opt/libpng/lib/libpng16.16.dylib" (which I don't have)

Using "otool -L", I traced this to libfreetype.6.20.0.dylib and libfreetype.6.dylib in /Applications/Meld.app/Contents/Frameworks. So that is at least one issue.

[stevejordi]

Same for me.. Sonoma 14.1.2 on Intel and it doesn't work. I don't think it's really M1 related but much more system related

Meld 3.21.0 (r4) Sonoma at 14.1.2 with Apple silicon

Hope this snippet can help everyone; I've successfully used it myself and wanted to share it with all of you.

Still crashing on Sonoma 14.2.1 with M2. Crashes when opening from command line with two folders as parameters. I have seen it run if I opened it without any input for comparison.

[jonatan-ivanov]

With meld 3.21.0.osx3 and macOS 14.2.1 (23C71) (Sonoma, Intel), I'm getting:

/usr/local/opt/git/libexec/git-core/mergetools/meld: line 172: 19388 Segmentation fault: 11  meld $LOCAL $REMOTE

I'm using meld with as a git difftool:

[diff]
	tool = meld
[difftool "meld"]
	cmd = meld $LOCAL $REMOTE

But it does not matter, it crashes purely through the UI too.
