My Mac keeps renaming itself by adding a (2) to the sharing name. I have 3 Macs on on a network (no Windows) and this happens after the Macs wake from sleep. Each Mac has a unique name and each time I take off the (2) or whatever number it has added to the name, it happens again randomly later. I think part of the problem is each Mac connects to the network via Ethernet and wifi. I need Ethernet for speed, but Apple's "Find my Mac" feature only works with wifi so I need that on too. Any ideas if there is a workaround for this? I've trawled the forums for days and can't seem to find any answers.
