If I erase a computer I no longer own will it erase new owners data

"If I erase a computer I no longer own will it erase new owners data: Yeah I kind of figured that. I aim positive I signed out of Apple ID before I wiped it. But apparently apple still leaves fragments around. I have learned that you need to sign out of every single thing that connects to iCloud and Apple's ecosystem. One major sign out from your Apple ID does not do it."

Removing Devices:

So, can you get in from of this Mac again? If you are able to log In to it, then remove the device. It's no more than a matter of Security & Privacy. Seems simple enough of a solution. Go Here: View and Remove your Associated Devices for Purchases - Apple Support

90-Day Limit:

A device can only be associated with one account at a time - once every 90 days. So, if it is not going throgh, then they may have to wait until they can assist it to their own account.

Call Apple and Screenshare:

So, get infront of the computer once more, and perform all of this. If need be, contact Apple Support once more, and have them run you through the fix. This time, however, perform some screensharing, on an iPhone and your Mac.

Screensharing with the Apple Rep:

To easily perform this over the phone with the Apple Rep, screenshare the camera of your iPhone and screenshare your Mac's screen. Ask a friend, or family member if you may use their phone, if you do not have none handy. This will allow the Apple Rep to see this firsthand from your perspective.

Why Calls are a Bit of a Wait:

Phone calls are taking a bit to go through at the moment, due to lots of calls. And, that makes sense because with the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple Support. So, just stay on the line, and you will get through :)

Try This: Turn off Find My on your devices - Apple Support

As it reads: If you no longer have the device, you can remove it from your account using Find My iPhone on iCloud.com.

The only choice I have it to erase it, but will that also erase the new owners dad? [...]I don't want to erase it either because I am afraid it might erase his data. So somehow I need to get my Apple ID off of that computer.[...]So if I can get in touch with him, how would I go about getting my ID off of it without messing any of his data up? I"

Contact them:

The only way to do this would be to do so in-person with the device in front of you. Don't share your Apple Credentials with anyone, as they might be able to purchase something (or confiscate it).

You can do a time machine back up of the new data, before factory system reset.

or log on https://appleid.apple.com/ and remove it from your account.

Ok... I understood what you were talking about. Try and logon to your Apple ID and try to remove it off your account.

oh, whoa... yeah. Any other way would erase it and we don’t want that.
