Not sure where to post this as it really applies to the Apple Online Store itself. On my iMac running 10.6.3 I can't check out on the Apple online store. I can add items to my cart (doesn't matter what it is: i've tried various items). But once I go to check out it asks me to login and when I do I get taken to a page that says "An error has occurred during your session. Please return to the Store Menu to continue shopping." No matter how many times I try to checkout, I'll get the same error. However, if I login to the Apple store from my Macbook Air running 10.5.8 (which recognizes me as the same account as the same items will show up in the cart) I can checkout fine with no problems. So same network, same firewall settings, same Apple account, but one computer won't let me check out without error and one will let me checkout just fine. I have no clue what could be causing this. It's a very curious problem as it doesn't seem to make any sense. Any ideas?
