Wanting to run Pd -nogui I've been thinking that such a feature for osx would be great (heard it's possible on Linux, but no idea which flavor what so ever), since the laptop becomes solely the audio (or video) engine and you're no longer 'checking your email', and found this: http://semaja2.net/insomniaxinfo
It lets you close your laptop's lid and the computer keeps running. Just thought of sharing it since others might have similar thoughts..
