This is not a scam, it is a purchase of a macbook with sats using an intermediary to swap sats for fiat.
The triangulation scam is when the scammer opens an offer to buy sats and another one to sell an item. The buyer of the item pays to the btc seller. The scammer gets the sats, the btc seller gets fiat, and the buyer gets nothing. Then the buyer reports the btc seller.
