To many iCloud accounts error on a brand new MAC?

I had the same reaction as ku4hx—someone fraudulently sold you a pre-owned computer as new. Those reports are very common in this time of shortages, production delays, and high demand.

to see the warranty information. It won't show past owners but, if it shows no warranty coverage, you know the computer is not new. This is what the report for a covered Mac looks like. Not the expiration of coverage dates.

The date of coverage expiration, if shown as in the above example, can allow you to approximate the date of original purchase but not former owners.

The second example shows haw the reprt will indicate no coverage available; the warranty has expired and the device is over a year old:

There is too much fraud involving pre-owned Macs sold as new for me to buy from anyone but Apple. In some countreis tou cannot even trust the resellers.

Where did you buy it? It sounds to me you bought a used machine thinking it was new.

Your situation is not hopeless necessarily, but you need to know if it's used or not if for no other reason than to possibly confront a questionable seller..

My wife's first MBP, a 2020 intel model, showed up broken right out of the box. We immediately, that day, took it to the local Apple store and they exchanged it immediately.

I say that to say this, Apple does every now and then send out a defective product ... we got one.

I suggest you take it back to Apple with Apple receipt/proof of purchase in hand and demand, nicely of course, they make it right.
