    Clamshell Mode Performance Issues: A Myth?
    A while back, I remember hearing a theory floating around that running a Mac in clamshell mode forced OS X to throttle the processor to save on heat. There is a tiny bit of anecdotal evidence to support such a claim (here)which ultimately suggests that something about clamshell mode might be slowing down the performance of the machine. As someone who runs his machine in clamshell mode quite frequently (the compulsive neat freak in me loves that it saves me space on my desk), I decided to put this to the test

    Nice work there and quite timely for me. I may be purchasing a new Mac in the near future depending upon whet happens with the Mac Pro line. If I do that I'll probably turn the MacBook Pro into a media machine, connect it to the TV, and run in clamshell mode.

    Interesting. Do remember the WiFi Antenna is usually in the LCD Lid. When it's all the way down like that maybe it's shielding it in a way and lowering WiFi signal reception strength. Only thing I can think of this late!

    I use my MBP almost exclusively in clamshell mode at home and I don't have a problem with network connectivity. Is it only in clamshell mode that this happens?

    The antenna for the airport card is located in the lid along with the LCD and various cables. Have you recently changed out your LCD? Any disturbing or moving of the antenna wires can cause poor reception - especially when the lid is closed.

    My 2006 MacBook (that is now retired and will be sold along with other macs very soon)

    Is too slow to even use in Clamshell mode.
