Apple’s ordering system is absolutely useless. Every year it is the same problem and it seems they don’t care. I tried on the app and on my MacBook and couldn’t get into the store until 6 minutes after the original time. I was able to order the 17 and 17 ProMax to deliver on 09/19 but they were not available to pick up at any of the 6 Apple Stores around me. WTF 🤬
