Thank you for reporting. I can confirm that Kdenlive crashes on Intel Mac after the splash-screen. It could be a certification issue.
Comment 2 Jean-Baptiste Mardelle 2025-03-14 13:32:40 UTC 
Not sure if it is relevant, but could you please confirm which MacOs version was used on the system that crashes ?
Comment 3 emohr 2025-03-14 16:33:05 UTC 
Mine is a Mac Pro with OS 13.7.3
Comment 4 qrhy 2025-03-17 13:40:55 UTC 
I can confirm emohr's suspicion that this is a code signing and certification issue since kdenlive starts up successfully after manually replacing the signature. Tested on 13.7.4 and 14.7.4
Comment 5 emohr 2025-03-17 16:03:03 UTC 
Thank you for the feedback. That is interesting. Let me know the steps you have done to manually replacing the signature. The I can test on my Mac as well.
Comment 6 qrhy 2025-03-17 20:09:33 UTC 
Of course! You can replace the signature using Terminal by running:
codesign --force --sign - "/Applications/kdenlive.app"
Comment 7 emohr 2025-03-18 18:14:18 UTC 
Success.

I had to login as administrator and run:
sudo codesign --force --sign - "/Applications/kdenlive.app"

Then I got the error:
/Applications/kdenlive.app: replacing existing signature
/Applications/kdenlive.app: Operation not permitted

On top right it appears the message: “do you want to give Terminal full disk access?” and I clicked on yes. Restart the terminal and run the same command again and it have replaced the existing signature and Kdenlive starts.
