Wake On Lan Mac Os Terminal

Wake on LAN is a feature built into the NIC (the Ethernet card), and then the OS must support it too. This is one of the things, in the PC world, that determines one the differences between a manufacturer's home computer line (like Compaq Prosario), and business computer line (like Compaq Deskpro).

Hardware Requirements

First, confirm that you meet the hardware requirements for using Wake on LAN:

Wake on lan mac os x command line
  • Confirm that the computer is on a wired network (not WiFi). Wake On LAN is not supported for Mac hosts on a wireless network.
  • Make sure the host is in Stand-by, sleep, or hibernation (ACPI specification S3 or S4) mode.
  • You cannot wake a Mac that is powered off.

Adjust the Power Management settings in a System Configuration file

Check the Power Management settings on the Mac you want to wake up.

  1. Open Finder.
  2. Navigate to SystemConfiguration by going to Go > Go to folder and typing /Library/Preferences/SystemConfiguration/.
  3. Open the following file: com.apple.PowerManagement.plist.
  4. Set the <integer> Wake On LAN </integer> value to 1 for the following <keys>:
    1. <key> AC Power </key>
    2. <key> Battery Power </key>
    3. <key> UPS Power </key>
  5. Restart the Mac.

    Wake On LAN should be available.

Adjust the Power Management settings in Terminal

  1. Open Finder.
  2. Navigate to Terminal by going to Go > Utilities and double-clicking on Terminal.

    The Terminal window is displayed.

  3. Type pmset -g live.

    A table with settings and values is displayed.

  4. Look for the value womp and verify that it is set to 1.

    If it is not set to 1, you can set it with the command sudo pmset -a womp 1.

Further Resources and Information

Make sure the host is in Stand-by, sleep, or hibernation (ACPI specification S3 or S4). You cannot wake a Mac that is powered off.
