I typed Mac Help about "to operate the portable computer with an external monitor attached and the display closed. When I close the display of my Mac Book or MacBookPro, the external monitor such as my 50" Plasma monitor or video projector would go black. I read the Help and it said and required the USB Mouse and Keyboard to close the Macbook display and put computer sleep. My question is will the Apple blue tooth or wireless keyboard and mice will work with out using the USB? Has any one try that? I am not sure if I should buy wired or wireless to operate this. Thanks for your time and answer my questions.
