Sadly, first I don't have the expertise to prove what I found is indeed a bug and secondly I really don't know how to report them to Apple and rather try to find a solution to my problem(s) instead of trying to figure out how to do so for Apple, what Apple should do for me (i.e. providing me with an easy way / instructions to report bugs!).
So the title says it already: Can I post a question related to an issue that is clearly not supposed to happen and of which I assume can't be solved by a simple answer?
Additionally I wonder when / if it is OK to use the "wording" and the tag bug at all? What are the Stack Exchange or Ask Different community guidelines for using it?
