Hi Everyone! I've got a 2008 MacPro 3,1 (OSX 10.11.6) and a PowerMac G5 (OSX 10.2.7) which I would like to network together. Basically, I tried putting an Ethernet cable from the second Ethernet port on the MacPro to the Ethernet port on the G5, but I cannot get it to work. Is it because the G5's OSX is too old? The MacPro is the everyday computer (and home media server), and the G5 is something that I am holding on to so that I can play Macintosh games which were never ported to the newer Intel Macs. Any help or advice would be much appreciated!
