On your iMac, go to System Preferences > Network. Select your active network connection (e.g., Wi-Fi or Ethernet). The IP address will be displayed in the network information panel.

What type of cable do I need for Target Disk Mode?

The required cable depends on the age of your iMac and MacBook. Older models may use FireWire, while newer models typically use Thunderbolt. Ensure you use a compatible cable.
