Can't get wbfs to show on Wiiflow or USBloader

Hi there all

I recently bought a Wii with all the software to play retro stuff etc. which works fine downloading or ripping the games i have off to play :) But I have an old copy of Tiger woods 12 on Wii but it has a dirty scratch on it & wont play, tried to install no luck eiter. So downloaded a wbfs copy & put it into the folder wbfs under a separate sub folder tiger woods 12 & it doesn't read in wiiflow or usbloader :(

I have a macbook so cant get a wii manager either, any suggestions?. one of the main games wanted to play again with the wiimote was tiger woods 12 the masters. but to buy the same copy i got here with a massive scratch on is like £65 on amazon haha

Thank you :)
