Activation lock removal
I have a MacBook that I purchased in September of 2019 from an Apple store in person. I've been trying to sell the MacBook, and I had a person come over and sign in to the MacBook but they decided not to purchase it. I am now stuck with an activation lock from this persons Apple ID, and they are not responding. Is it possible to take my MacBook in to the Apple store and have them remove the activation lock if I do not have the original receipt? The only proof of purchase I have is a bank statement from the exact Apple store on the day I purchased the device. Would the Apple store be able to look this up?
