Can you provide a log file? GCN injects have never worked on my Wii U, so it's the one part of UWUVCI I don't touch since I'm unable to test it. I guess that the tool that's used for nkit doesn't work on Mac, but if you provide the log file, I'll truly be able to know.
The error message tells you where to find your log files C:\users\ryanharmon\AppData\Local\UWUVCI-V3\Logs If you do the same thing and get an error message than go to that Logs folder and grab the most recent log file, and paste it here.
