Hi, I wondered if anyone had any input on what the minimum requirements in a new iMac would be to operate to live stream toggling between 2 USB webcams? I attempted to run two with my existing (older) iMac with High Sierra OS and naturally the VTDecoderXPCService just drags it down too much. Keeping in mind that it is a 2009 iMac that I attempted it with. Also I started playing with the basic settings but ultimately figured I was fighting a losing battle with an old computer. Any information or ideas would be great.....Please & Thanks
