Is there a terminal command within Mac OSX that will allow me to use WOL (Wake On LAN) to wake up other computers? Windows has wolcmd, is there an equivalent within OSX?

I am trying to wake a computer from my rMBP, within my network. My rMBP is connected via WiFi normally, but can also be connected via Thunderbolt GbE connector. The target computer is a Windows machine that I want to wake up before I connect to it using a remote desktop connection.

@Buscar, On my mac (OS X 10.8.4), I get -bash: /Users/Dygear/bin/wakeonlan: No such file or directory. – Mark Tomlin Jun 30 '13 at 10:11

wolcmd is available for Mac:

GUI version for $1.99, terminal version is free. Usage is just the same as its Windows counterpart.

The wakeonlan command for command-line can be added to OS X using the homebrew package manager.

Install the wakeonlan package using Homebrew:

$ brew install wakeonlan

(It's a Perl script for waking up computers via Wake-On-LAN magic packets.)

When installed, you can send a "magic packet" from your Terminal to any device using its IP (Internet Protocol) and MAC (Media Access Control) address.

Here's an example of a typical use:

$ wakeonlan -i -p 1234 01:02:03:04:05:06

The scripts takes 2 arguments, the MAC address of the NIC, and an IP address.

Note: The IP address argument is tricky and isn't what you'd think.

For a NIC on your local subnet, use the broadcast-address of this subnet. (e.g. subnet with netmask, use

For example, I have a Synology NAS manually configured with the IP address of with a subnet mask of and a router address of

The correct IP address to use is not that of the device, but instead the broadcast-address of the subnet.

Continuing on my example, I used the following command to successfully wake up my Synology:

$ wakeonlan -i -p 7 01:02:03:04:05:06

(Naturally, substitute the actual values of your device and network for your situation.)

You can get more information from the wakeonlan man page, man makeonlan, or a quick glossary of commands from wakeonlan -h.
