A simple tool dumping active NSFilePresenters / NSFileCoordinators. Just build and run "filecoordination-dump" as root.
This tool is not needed on macOS 10.15+ up to macOS 14. To get a dump of all file coordinators, you can now use:
fileproviderctl coordinate -e
On macOS 14 this command will fail without an error. It's still unclear why, but in this case you can use filecoordination-dump on macOS 14.
