I used to have an Apple ID that I shared with my family, but it was becoming more and more obvious that I would end up needing my own. So I got myself an Apple ID, got family sharing set up, and switched everything out on my iPad. When I got to my computer, things got more complex. First, I logged out of iCloud and logged into my Apple ID instead. Then, I switched iMessage, FaceTime, Game Center, and a few other things. The problem is, my computer is still showing remnants of the old Apple ID. Is there a way to completely switch Apple IDs with one login on an iMac? Or do I just have to switch everything as I go along?
(Edit:) It would be too inconvenient to create a new user account because I have a lot of settings to applications adjusted and my computer too rigged up.
