I don't know if this is the right place to post, but it may be useful to people using applications with embedded Finder Sync extensions. For some reason (maybe imminent deprecation and discontinuation), Apple removed the Finder Sync extensions configuration interface from System Settings in macOS 15 Sequoia. Managing these extensions on Sequoia is possible only using the command line tool pluginkit. FinderSyncer enables the same functionality, but in the neat user interface.
