Every time I try to connect to Xbox live, I need to update my system. It comes up with the error message xxxx-xxxx-xx8x-xxxx-8007-2741, I've tried updating it with a CD but it does not work. I only have a Mac and not windows so I hope thats not why it won't read the CD. I have also tried updating it with a USB before using windows to upload the update to the USB, and it still does not work. Is there any way to see if I can connect to Xbox Live without updating the system first, just to see if it is the xbox or the internet itself.
