I had also used the Macbook for a whole month before this issue arose. I understand beta software comes with bugs but as a user who uses Xcode to build applications I had a reason to install it. The second issue is that the activation lock got triggered after I was attempting to install the Big Sur beta software in the beginning of July. My whole gripe with this problem is that there was no previous person who we could contact to get the details to remove the activation lock since Apple never removed the lock when they refurbished it because the previous owner before me bought it sealed refurbished from swappa so he was technically the first user to attach his iCloud on the Macbook Pro after the refurbishment process. I had bought two Macbook Pros before this (2014 15” and 2007 15”). This was my first time purchasing a secondhand Macbook that was made after 2018. However before the T2 chips were introduced to the macbooks(2018 and later) All that was needed to make sure that the Macbook was safe to use was to make sure no iCloud account was attached. I understand now that I should have probably not bought on appleswap without the original reciept. The only way it was going to be resolved was with an official apple reciept. None of this was enough to remove the activation lock. I sent whatever information I had and the previous owner had from appleswap (swappa reciept showing serial#, paypal reciept, screenshot of the macbook being under my iCloud account. Spoke to Customer Relations and nobody was able to remove the activation lock. Wrote to the Apple Developer Team support. Went to the apple store and had a genius tech help me. I went through multiple senior apple advisors. So the original owner(person from swappa or whoever sold it to him did not have the apple reciept which was required by the activation lock team to remove the lock. I bought my 16” 2019 Macbook Pro here through r/appleswap and the previous owner bought it sealed refurbished through Swappa.

The removal of activation lock will only be resolved by submitting original Apple Store receipt.

This is a Public Service Announcement for everyone to make sure to obtain an original Apple Store receipt when buying a secondhand Mac.
