I would think the fact that they don't have an official bug bounty program makes it unlikely they have an unofficial one.
Why is that? It seems to me that there are a lot of ways to run bug bounties, although I haven't thought through the details of Apple keeping theirs official / unofficial, it seems one could have arguments for having none, both, or either, depending on who you are and what kinds of bugs you are trying to get people to tell you about.
