Can I use a 24 inch (early 2009) Imac as an additional display with the latest (2013) Imac??
Welcome to the Apple Support Communities
Only 27-inch iMacs and Mid 2011 and newer iMacs can be used as a monitor. However, you can use ScreenRecycler to use your 24-inch iMac as a monitor, but it works through the network, so it will be slow
