Hi Alan,
Somebody reminded me that there was an issue with drag-and-drop to Chimera on Catalina, as discussed in this post from a year ago:

There is no fix for Chimera, but it works fine in ChimeraX.  Our group's development efforts are all on ChimeraX now, and you may want to consider switching.  It has many of the same features (fitting, segmentation, etc.) and many advantages (better on large data, many usability improvements, and several entirely new features).


Salient features that are still missing are listed in a section on the download page (click the triangle to expand the section), and certainly you can install both programs and mix-n-match usage as needed.

I hope this helps,
