How do I adjust the settings on my MacBook so it doesn't automatically open things when I turn it on?
Open up System Preferences then search for Login Items


Then find the list of items and delete the ones you dont want to open.


Note: You must click the subtract button or else the item will still open up. I don't know what the tick does but the item will still open even if its not ticked. The application must disappear from this list or it will continue to open. (eg. Docker, Thor and Kawa are not ticked yet they still open on startup for me)
