I’m getting this error message everytime I launch Rapidweaver:

**RapidWeaver failed to load some plugins**

**RapidLink: Couldn’t obtain plugin principal class**

**RapidMaps: Couldn’t obtain plugin principal class**

**RapidViewer: Couldn’t obtain plugin principal class**

At the very least, I would like to remove them from Rapidweaver but can find any reference to the files.

Any suggestions on how to delete them so the message will go away?

You can enable Rosette mode for Classic in macOS to make these old plugins work, here’s how to do it:

Excellent. Thank you for the solution. I’ll see if It works on my M4.
