Apparently the 'silent patch' dealt with Gatekeeper specs and thus applied to OS X well beyond the Lion version.

If such a 'silent' fix was indeed attempted, it would have to have been while I was online and it would have to have been downloadable at 1-4 MB/s and then installed. Unless the patch was tiny, in order to fit such constraints, it wasn't done.

Other than the downloads I've initiated/permitted, there is no sign of any such patch on my system.
