We use a Mac airport and have a Snow Leopard Mac, and we've connected in the past, but now the screen says that we need an update that can't be downloaded. Initially, we downloaded the update directly and tried to install it onto the xbox from a cd. Now we are being told that a system update is required to sign in to Xbox Live, but that the update is currently unavailable. I've tried all of the support page's suggestions, and nothing has worked.
Thank you for your help.
