Did you purchase this notebook new directly from Apple or used from a third-party source? If the latter, that source did not properly prepare this device to be sold and potentially still has the original owner's apps/data on it. Are you still able to contact them? If so, provide them with the following article: What to do before you sell, give away, or trade in your Mac - Apple Support
