I have just received a 2019 MacBook Pro, sealed in the box. During the installation, I chose to "Setup Later" my Apple ID. When it came to the Find My screen, it said:
Find My will use the Apple ID "email@example.com"
That looked suspicious, so I took a picture and finished installation. Post installation, no apple ID was seen in System Preferences > Internet Accounts and consequently Find My was not active.
The installed OS version was 10.15.4.
I figured this was another Catalina bug, but paranoid of the worst, I restarted and command-R, went back to the installer, erased the drive, switched networks, then reinstalled the OS from the network. Again, following the steps, I didn't enter my apple ID and when I got to the Find My screen, it still showed this random email address.
I installed 10.15.4 on a different device earlier today, a MacBook Pro 2016 model and it did not have this behavior.
Is this a bug or infection at the source (Apple) or an issue local to this new MacBook Pro 2019 hardware? What should be my next steps?
Update: Reset the NVRAM and now the MacBook shows an activation lock, which is consistent with this machine not being new and instead being refurbished.
