Purchased in April 2023 (see shipping label) Ended up getting the new 2023 MacBook Air 15.3 model which had a diff charging port. Hence, I have no use for this now. It is authentic. Idk if the shipping label helps prove that? I purchased straight from Apple as a backup for my 2015 MacBook Air because I’m too afraid of the Amazon knock offs that catch on fire lol Make sure it is compatible with your model (see pics or go to Apples website). Feel free to ask questions, make an offer, etc. 😊
