Hello~ Okay, let me start with a little background info. I have a MacBook (4 months old). My husband has an iBook (an early 2005). We have a family .mac account, and my husband also has an individual account. We bought my MacBook and the .mac family account because everything was supposed to work so great together. I am in Hawaii using two different types of connection, depending on where I am. T-Mobile HotSpot when not at home, and Clearwire at home. My husband is in Iraq, using who-knows-what. We do know that the other two people, using the same connection, video chat with their wives on PC's using Yahoo with no problems. We can text chat on both programs with some fairly frequent problems, but on an acceptable level. We cannot audio or video chat on iChat at all. We can video chat on Yahoo, but only one at a time. And it moves so slow you'd think we were using a decade-old technology, and it pulls the POOF! vanishing trick every couple minutes. Needless to say, it gets old fast. Does anyone know any REAL possible solutions? I have read some of the threads of similar issues, and it seems that everyone glosses over the fact that there is a real problem with Mac and iChat. I don't need anyone to stick up for the Mac movement. I am in general pleased with the computers. It's just that this is an important feature for us right now. Thanks for your help!
