so, i have a macbook air running mountain lion, an apple tv & the iPhone 4s. what i'd like is way to wake my macbook when it's closed so that the ATV can access the home sharing itunes library for music. i have the app 'touchpad' on my iphone which will let me control the macbook. when i had a mac mini i could wake that with touchpad.. are the MacBooks just 'heavy sleepers' and it takes more than a nudge to wake them up? ..do i need a cup of cold water to wake it from it's sleep? any suggestions?
