I currently have a Mac setup in my home office. I have an Ethernet connection at the wall currently connected to my Mac Mini. I’m going to be adding a PC to the office for work related stuff. I also want to connect it to Ethernet, but I just have 1 line coming from the wall (The router is in the garage) do I need a switch or a splitter, or are they the same? I want to be able to jump from either computer as needed without having to change settings or make a change to the plug. Any advice would be welcome.
