I have an iMac, an iPad 3 and an iPhone 4S. I was assuming that after updating the iOS devices to iOS6 and my iMac to Mountain Lion 10.8.2 that any messages I receive on my iPhone would be seen on both my iPad and my iMac? This is not happening for me. Only messages that are sent via an Apple phone can be seen on the other devices, I thought that ANY message received would be seen. Is this the case or have I interpreted the new update features wrong? Or is something not set correctly in the message settings?
