Why does ATV2 wake up and put my Mac to sleep?

    I recently bought an ATV2 and I have home sharing enabled with my Mac Mini. I have been finding recently that if I have my Mini on and turn on the ATV2 (out of sleep mode), iTunes on my Mini opens up on its own and starts playing music by itself. In addition, I find when I turn off the ATV2 while the Mini is on, three Z's show up on my monitor and the computer goes into sleep mode. If the Mini is in sleep mode when I shut down the TV/Receiver/ATV2, the Mini wakes up.

    Can anybody tell me what is going on here and how to make it stop?

    Most likely that the Mac is picking up the remote as well, so it thinks you want to play music.

    You can turn off the remote detection on your Mac under System Preferences, Security and Privacy, General, Disable remote control infrared receiver.

    Thanks for the reply. I should have been more clear that I am using the Remote app on my iPhone for control of the ATV2.

    Usually when I go to watch the ATV2 it is already in sleep mode. The ATV is plugged in to my Onkyo receiver via HDMI, which then obviously goes to the TV. I use a Harmony remote to turn on the TV and receiver when I want to watch ATV. Somehow the ATV also turns itself on at that point. I am guessing it gets some sort of signal via the HDMI cable as the receiver turns on. As soon as the ATV turns itself on, iTunes on the computer either boots up or starts playing music if it was already open.

    When I turn off my receiver and TV via the Harmony remote (using the single "off" button), it ends up putting the ATV to sleep and that's also when the three Z's show up on my computer monitor if I'm using the mini. The mini then goes into sleep mode.

    Are you sure the ATV2 isn't programmed as a device on your Harmony?

    Nope. I have an ATV "activity", but it only controls the Onkyo receiver and TV. I I didn't realize that the ATV2 utilized an IR sensor. I figured it was only BT. I've been using my iPhone as the remote so it never occurred to me. That being said, the ATV2 isn't listed as a device in the ATV activity so in theory the remote shouldn't be interacting with the ATV at all, right?


    *UPDATE*

    Apparently this actually had nothing to do with the ATV2 at all. For some reason some IR signal being sent from the Harmony to the receiver/TV when turning on the ATV activity was telling iTunes on my Mini to open (if closed) and start playing music. When I would hit the "Off" button on the Harmony to turn off all devices it was sending a command to my Mini's IR receiver to put it into sleep mode.

    When I disabled the IR port on the Mini as described in the post above the problem went away. Definitely strange since I don't have the Mini listed as a device in my Harmony remote settings. Oh well, works now.
