This is indeed a translocation problem. My app is an audio app that need to access some Impulse Response wav files to create reverberation. I have a preset folder next to it where the users can put their own wav file to have it available in the app and create their own reverbs. that is why I need this folder. Also the app should be able to copy paste some files in its own folder, like the license file. What I don't understand is exactly what is not documented on Translocation. what is also weird is that for the previous versions, it worked perfectly. Is there a way to scan what triggers this translocation ?

@eskimo Thank you for your help, the threads you mentioned were very helpful I finally managed to distribute it cleanly by packaging the application in a dmg. It also eased the notarization and stapling process. As I'm developing the app with Max/MSP (a graphical real time audio framework allowing to package audio application), I was forced to keep the same architecture as I don't have access to all convenient functions and method for the file management of the app. It seems that using a dmg and forcing the user to drag the app in the application folder disables the translocation. Here are some resources that also helped me to understand translocation : https://eclecticlight.co/2022/09/06/dont-run-that-app-where-it-landed-how-translocation-can-cause-crashes/ https://eclecticlight.co/2023/05/09/what-causes-app-translocation/
