According to Apple, the only way to remove an unknown firmware password from a MacBook (2011 and later) is to take it to the Apple Store with the original proof-of-purchase. However, I've found that there is another way, which I've been successful with for the unibody MacBook Pro--it's essentially just modifying a couple bytes in the EFI ROM, which should be simple. What's not simple, however, is figuring out how to read and write to the EFI chip. In this post, I'll talk about the process that I figured out and what worked for me.
Apple's method of resetting the firmware password is not reproducible, as Apple generates an SCBO file that unlocks the EFI using their private key. You can read more about this process here. The problem with this system is that, if you are in the unfortunate situation of neither having the firmware unlock pass
notice: Wii U linux is not production ready! Proceed at your own risk. Written on 2/3/18
Quarktheawesome and rw-r-r_0644 have released an early version of Linux for Wii U!
The PowerPC side of the Wii U requires a custom linux kernel, which can be found here. The ARM side of the Wii U requires a custom fw.img file to load that kernel, which can be found here.
Once the kernel is up and running, the first repo is configured to automatically try to load programs from /dev/sda1 in an inserted usb. The first partition of an ext4 USB stick should contain a root filesystem for a linux distribution. See here for more information on a prebuilt PowerPC image
