How to remove greyed out and incorrect apple ID and replace with correct one?
When I try to sign in to the apple store to download from the App Store off of my computer it has an incorrect apple ID in the place where I need to write my apple ID in this spot or erase his ID (it is greyed out also). The apple ID is that of someone who worked on my computer in the past. Therefore I can not download anything from the app store. I have tried to reset the system by telling it I have forgotten my apple ID and password, but after I go through the process and go back and click on apple store again, it is still showing me this techs apple id where I need to write in my own. Meanwhile I am not updating anything related to apple, so I need to figure this out.
