You may had heard of this free tool from the Mac App Store, iClapper pro. I find it pretty useful for playing iTunes songs. Just a little problem: I want to use it when the Mac is on standby. I mean when I come home or use walk near my Mac, I often want listening to some music, but turning it on needs some time. Is there any option for letting iClapper wake up my Mac and playing iTunes music just with a single clap?
