Change MacBookPro M1

We haven’t gotten to June 26. Did you mean May 26th? If you have not received your Mac, you can cancel, and re-order. If you have received the Mac within the last 14 days, you can return it to Apple for a refund. If you have had the Mac longer than 14 days, you will have to sell it privately, and purchase new

Today is 14 days past the date of purchase. You would need to return the laptop if you already have it no later than today.

You have 14 days: Returns & Refunds - Shopping Help - Apple

Within that window, you will have to return, and can then re-order.
