I am sorry to hear you are having this problem with the system.
Please note that the support on Mac units is provided by Apple only so my recommendation is to contact them for further assistance.
The problem is not with the systems or the hardware, but the software driver. So technically, you should feel sorry about THAT instead of my systems, And by the way, please note that just because the units were made by Apple doesn't automatically absolve Intel from its responsibilities. Bootcamped Mac systems may not get official support from Intel, but I'm not asking it, This is a support community and I appreciate any help from anyone. Unfortunately, your comment doesn't appear to be helpful, but thanks anyway.
