I have a macOS app which uses FinderSyncExtension. From the MainApp, I'd like to know if FinderSyncExtension is enabled. For that, there is isExtensionEnabled class property in FIFinderSyncController, however it always returns false.
Does anyone know correct usage of FIFinderSyncController.isExtensionEnabled or in which case it would return true?
It works correctly for me when running OSX 11.6.1. I'm using it just as you show, if !FIFinderSyncController.isExtensionEnabled {}.
However, I'm just now investigating why I always get false on a system running OSX 12.2.
I'll probably go post on the Apple Developer forums, hopefully Eskimo will answer.
