Thanks again ! In fact App Review approved my app with the temporary entitlements, yesterday ! I guess they know that the target groups are a mess ? 😅 In any case, thanks and if in the future I find the time to debug and perfect, I’ll try your suggestions ! 😊

Hey, thanks for the answer. No I didn't try the Photos framework. At the beginning, I wanted something quick and easy, calling osascript but that didn't work, so I implemented it in objective c using NSAppleScript. I've spent so much time trying to understand what's not working for the sandbox, it's really annoying. In the end you're right, it might've been easier to use another approach 🤷‍♂️ I mean, it works now, using the temporary exception entitlement. But I'm still wondering what is wrong with the indicated, "Apple Approved" entitlements of scripting targets ...
