How do I delete a question

There is no Directly way.

They will remove questions of the question is deems as not complying with the Rules that Govern the usage of the Forums but generally a request to remove does not occur.

If you are the owner of the question and do not what to receive additional reply or advise - sometimes marking the question as Solved ( Green Badge) will alert others to bypass the question.

One the " Moderators " of the Apple Support Community can delete a question.

If and only If this it is so important to remove the posting - if you what to supply a link in that question - we can request the removal at the Moderators total discretion

You are welcome and thank you too.

Glad to be of assistance 

Do come back to the Apple Support Communities ( ASC )  in the future, if / or when additional questions may arise
