Used Macbook. Find My associated with another account.

And who is this "reputable refurbished Macbook seller online" ?

They obviously did a very poor job of prepping the machine—it makes one suspect.

However, I'm now the recipient of this laptop that was not disassociated with the device. I went through all the steps already but it still does not help my issue. My Macbook is associated with another Find My account and I'm trying to figure out how to disassociate it.

Maybe Kurt Lang is correct—useless.

Otherwise In your case—maybe trust to your luck at some point, the previous owner disassociates from that Mac.

As long as you can get it up and running: ie AppleStore, itunes etc.

You would be at risk getting locked out or data wiped. Having a good backup plan.

Have you talked to the "reputable seller" loosely as they have 1000s of positive reviews" and ask them?

The seller should've done this before sending it to me.

That's exactly what leroydouglas said - They obviously did a very poor job of prepping the machine…

Without the necessary Apple ID and password, the device is useless. Return it for a refund.

As a "reputable" seller, I'm very surprised they didn't check for this before putting the item up for sale. But then, you never know what they're going to do with used equipment.

I bought a used 2010 Mac Mini a few years back since I needed a Mac that can run PowerPC software to drive a high end, prepress scanner. It came from an Amazon seller (who likely bought it from a local owner). They had lots of high praise and remarks for the items they sold. Got it, works fine, but no one had wiped the Mac back to factory condition. The former owner's life was on it. Family photos, tax returns, bank statements, and lots of other information that would have allowed a criminal to take over his life.

Fortunately for the previous owner, I'm not that kind of person. I stuck a Snow Leopard DVD in the Mini and erased the drive.

Yes...I've actually returned 2 laptops already with the same issue and am on my 3rd laptop being sent out to me.

At least the "reputable dealer" is consistent in their incompetence.
