Help with debug

[sylman4]

I'm really new at this but I'm trying to dedrm a textbook I've downloaded for school through the Kindle App. I would really appreciate it if you could look it over for me and figure out what I'm doing wrong. Thanks! I've pasted the debug code below:

First, I recommend using noDRM's DeDRM because it has some Kindle for Mac related improvements. Then I recommend avoiding KFX format if possible. Take a look at method 2 in this post: https://www.mobileread.com/forums/showthread.php?t=283371

And also this post: https://www.mobileread.com/forums/showpost.php?p=3819708&postcount=508

ok got it. I think I'm getting somewhere with the KFX but I'm still having trouble with the DRM. Here's what I have now:

It looks like you're still using the older DeDRM v7.2.1. This version has a typo in the Mac key retrieval script.

Try the latest DeDRM v10.0.2.
