What do you mean by 'set up'?
You can use an iPad or iPhone to set up the AppleTV via Bluetooth...that process will use the settings from your iDevice on the AppleTV... And if your Mac is set to use the same network as the iDevice, and you've set the iTunes on the Mac to use Home Sharing, everything in the iTunes library on the Mac will be available to the AppleTV... You can also enable AirPlay on the Apple TV so compatible devices/apps can use the AppleTV to display content. There are lots of step by step instructions on Apple's support site...
