I do a lot of floppy imaging and some of my work on it has previously be discussed here[1]. I do not understand where they got the idea of "there are a number of disks that the Greaseweazle struggles to capture, namely the Apple formatted disks. If you have these disks in your collection, you may need to use an Applesauce controller."

The Applesauce is a macOS exclusive tool that has a contingent of dedicated users. While I have not imaged a wide sample set of Apple II and 800k Mac disks specifically, from my current experience the Greaseweazle is plenty capable of reading them. I would speculate the author was trying to use an included diskdef(a flux to binary decoding definition) for an incompatible disk. The Zone Bit Recording[2] Apple drives use is irrelevant when you increase the sample rate of the controller to accomplish the same thing. Similarly C64 disk drives are also ZBR but change the clock rate instead of media speed. So do not think that this means you need multiple drives and controllers when getting into floppy imaging, you can use standard PC drives with a Greaseweazle to read and write Apple II and Mac disks as well as almost anything else.

I have opened an issue on their github page for this site to seek clarification on this.
