I can not get the Harmony 1000 to communicate with a PPC iMac. I spent about an hour on the phone with tech support yesterday with no luck. I used my PC laptop to finally configure and get it working with my home theater with the RF extender and I love this set up. The 1000 work flawlessly with my theater. I have a Samsung LNS4696D LCD TV, a Pioneer Elite VSX-84TSXi receiver, a Motorola HD Comcast box, a Pioneer DVL-909 Laserdisc player, a Sony HDPS501P DVD player, a Sony SDP-E800 surround processor, and a Tivo DVR. Everything is being controlled with the RF extender because all of the components are behind doors in my cabinet. I will try to set this up using an Intel Mac and see if it works with it. No go on a PPC iMac, 1.8GHZ, 1.25GB ram, OSX 10.4.7.
