I have a Logitech Harmony universal remote, and it supports control of the iMac. The only problem is that when i switch "activities" on the remote, to "watch tv" for example, the remote shuts off anything that isn't used in that activity. So what it does for the iMac, is it puts it to sleep (via the IR port). Previously, I didn't even know this was possible, but it is. A icon comes up on my iMac that is a picture of the remote with some zZZzzz over it. Is there any way to disable sleep via remote on the iMac? It is kind of driving me nuts because when my gf wants to watch TV, it sleeps the computer, even if i am working on it!!
