How to Renew DHCP Lease on macOS 13

Renewing your Dynamic Host Configuration Protocol (DHCP) lease on macOS 13 Ventura refreshes your Mac’s local IP address and updates its connection settings with your router. This process is an effective troubleshooting step for resolving common network conflicts, IP address collisions, and unexpected internet drops without requiring a full computer or router restart. This guide provides step-by-step instructions to release and renew your DHCP lease using either the macOS System Settings interface or the Terminal.

Method 1: Using System Settings

  1. Click the Apple menu () in the top-left corner of the screen and select System Settings.
  2. Click Network in the left sidebar.
  3. Select your active network connection from the list (typically Wi-Fi or Ethernet).
  4. Click the Details... button located next to your active network connection.
  5. In the network configuration window that appears, select the TCP/IP tab from the sidebar.
  6. Click the Renew DHCP Lease button.
  7. Click Apply if prompted, then click OK to save the changes and close the window.

Your IP address will briefly reset and establish a fresh connection with your router.

Method 2: Using Terminal

For a faster method or to troubleshoot headless setups, you can renew the lease via the command line:

  1. Open Terminal (press Command + Space, type Terminal, and press Enter).

  2. Type the following command to release and renew the lease for your primary interface (usually en0 for Wi-Fi) and press Enter:

    sudo ipconfig set en0 DHCP

  3. Enter your Mac’s administrator password when prompted and press Enter.

The network interface will immediately request a new IP address configuration from the local DHCP server.
