@Andreas_Hegenberg I'm not sure if you are using the MediaRemote framework to get now playing information, but if you do, would you mind sharing your findings on how you got it working again?
I'm developing an app that uses the MediaRemote framework and it's been non-functional since the macOS 15.4 beta. I'm considering to use AppleScript to get now playing information, but I'd like to hold off on that until I'm sure the MediaRemote framework is actually inaccessible for user apps.
Thanks a lot!
