i have a properly sandboxed and codesigned app for macOS in objective-c. On Sonoma (macOS 14) i keep getting the dialog " would like to access data from other apps". According to Apple Developer this is a new security related message on macOS 14.2.
See here: https://developer.apple.com/forums/thread/742147
My App is developed according to Apples guidelines. E.g. using Open or SavePanels, Security scoped Bookmarks and so on. It does NOT try to access anothers app AppContainer (so this is whats confusing me).
My app controls another one by the usage of Apple Events but i do not try to access the apps AppContainer to read/write data.
CodeSigning uses a valid DeveloperIDApplication signature, Notarization also succeeds every time.
I searched through Developer Docs, Forums and so on and I am quite lost, just seeing that others got this issue too.
Any hint towards the right direction is very much appreciated.
This message pops up if you try to read data frm any other app(s container) that is not in the same app group.
In my case i send a script to InDesign that includes a path to a screenshot inside my apps Container (where I stored the image).
Once InDesign processes the script it tries to access this image and voila.
The onliest workaround I found so far is to create a subfolder in documents folder (requires users acceptance) and store the images there. Then InDesign asks (once only) to access that folder.
