Remote Capture Using Eos Utility - Canon Wireless Transmitter WFT-E6A Instruction Manual

You can use EOS Utility to shoot remotely over a wireless LAN.
In addition to remote capture, all EOS Utility camera operations except
firmware updating are supported, because this option utilizes a wireless
network instead of a USB cable.
The WFT-E6 cannot be used with the Mac version of EOS Utility (as of November 2011).
Check the Canon website for the latest system requirements, including supported OS
versions.
