To do this, simply select the disabled connection, click on the Settings icon in the bottom-left corner, and click on ‘Make Service Active’.)

(Note: If your system does not connect using any one of the alternative methods, you might need to enable the connection in the Network Pane in System Preferences. Once you’ve done so, OS X will re-establish an ad-hoc connection using one of the available alternative methods. However, if you’ve opted for Ethernet, Firewire or Thunderbolt, you’ll need to first disable Wi-Fi in System Preferences or in the Wi-Fi menu bar. Continue by skipping to the next paragraph. If you’ve chosen to transfer your files simply over Wi-Fi, then no setup will be required for you to connect your Macs. How To Connect Your Two Macs Via Ethernet, Firewire or Thunderbolt Also, this option may not be available immediately, so you might need to add it by clicking on the ‘Plus’ button in the Network pane in System Preferences and adding ‘Thunderbolt Bridge’ as an interface. Keep in mind that Thunderbolt is only available as a networking option in OS X Mavericks, so you’ll need to have that installed. Your third and final option is Thunderbolt, which is the fastest of all. Like Ethernet, Firewire is being phased out of Apple’s Mac systems but can be added using a Thunderbolt-to-FireWire adapter. Your second option is to transfer your file through FireWire. All you need to do is connect the both Macs via an Ethernet cable. If that’s the case with your system, you can buy a Thunderbolt-to-Ethernet or USB-to-Ethernet adaptor, although the former will be faster than the latter. Most new Macs don’t include an Ethernet port. However, you can make sure that this (and any other connections) are enabled in the Network pane in System Preferences.

Ethernet connections are standard and enabled on nearly all systems.
