Reply To: How do I reset my Apple MacBook? December 1, 2018 at 12:21 am #1336 Susie MorarParticipant@msusieI took backup of all mac book data. After backing up I did a scan with https://us.norton.com/macintosh-antivirus but nothing found. Even after scanning its running terribly slow.I think I should reset my mac-book now. Please tell me the easy step that I can follow.
