PS. Best intentions notwithstanding, I have never had any kind of solution from a community response.
I think we can help with that part a little. The forum section you found is, although totally unclear from the title, for Apple hardware mostly made before 2006. This section gets painfully few views.
We can ask the Mods to move you either to the OS 12 forums or the forum for your specific Mac computer model if you tell us what that is.
Either will get you more exposure from the really sharp people who like to help. LEt us know!
