There's absolutely no way that'll work as it's a WiiU accessory, not a PC-compatible one.
The best option for Wii games is to buy a pre-TR Wiimote Plus (such as the gold one from Zelda Skyward Sword) for Wii games, and a real GameCube pad and Ulao's BlissBox to connect it to your computer. This, however, could set you back a reasonably large lump of money.
Another option is to buy something like the XBox 360 pad (wired version) as this is compatible with computers out of the box (although I'm not sure on what you'll need driver-wise to make it work on Mac) and has all the buttons and analogue inputs that a gamecube pad has. It'll be enough for a lot of wii games too, but a lot will be a massive pain in the backside, and some are impossible without a real wiimote.
