Connecting Wii to iMac 10.6.2

Need steps on how to connect my Wii to my iMac.

If you don’t have the i-mac 27inch monitor with external video input then your only choice is to use something like this Elgato device to plug your console on your Mac


The Elgato hybrid works well with no time delays, but the picture quality isn’t the greatest from what I have heard.
