Please help!
A friend of mine logged in with their Mii onto my Wii U. I want to delete it from my system.
If I select "change user" it won't let me select the Mii because I don't know the password! And, of course, my friend won't tell me what it is.
I've tried blocking the Mii in the Miiverse - but that doesn't do anything.
I just want this Mii off my system - anyone know how I do it?
