Please share what worked for you as an answer, with enough detail so that someone else can repeat what you did. For example, "factory reset" is not necessarily clear to many people.
@digout First, this might help someone in some kind of related situation, but your comment is short and doesn't give context as to the exact problem it is solving. The OP mentions the problem survives a reboot, for example. So it is unlikely that killall will solve the question. Second, as a guiding principle, it is preferable not to ask people to just "try" typing various commands in their terminal without explaining what it will do. Third, your comment would be better as a separate answer. In so doing, you have plenty of space to explain, get votes, allow edits, and invite comments.
First, the term "factory reset" does not mean the same thing across various online resources. Second, the factory reset process can vary across Macs of different models. So I would request that you (a) describe your Mac model and year; (b) give a summary of you did (startup keypresses, and so on); and (c) linked to an official Apple page if possible. Part (a) gives context; (b) guards against link rot; part (c) provides more detail if the reader needs it.
