Hi, I have worked out a setup for my two macs so they both have backups and external file storage (see diagram). I have decided that I will need to set up some kind of network between the two macs but I am not really sure what to do. View attachment 91652 I have two questions regarding setting up the network connection: 1. I believe it is possible to set up a network between the two macs using just a firewire cable. How do I go about setting this up and is there any draw backs / things I should be aware of? 2. Someone suggested setting up a Gigabit ethernet switch. Could someone please explain this in detail, tell me what it is all about, (I have very little knowledge on this) the advantages and how to set it all up. If this is the way to go could someone please tell me what I will need or give some recommendations on products. Also any other suggestions / adjustments I could make to the above diagram to make it more efficient or faster etc.
