Hi,
Is it possible to unregister (or hide) an app extension (i.e. audio unit) from the system, such that only the app it comes bundled with can see/load it? If so, can this be done at run-time by the app it came with? For instance; for a list of plug-ins that comes with the app, can I selectively choose at run-time which plug-ins are exposed to other applications (i.e. Logic)? Much like the plug-in manager inside Logic, only for visibility outside the app.
A possible candidate for registering and unregistering is the 'pluginkit -a' and 'pluginkit -r', but the man-page states that it may get added by automatic discovery procedures, so I reckon there must be a better option.
