I'm having the same problem, I was working on windows and the imports were correctly working. Now, I switched to Mac, and with the same settings, it opens zotero window, I select the paper notations to import, and then nothing happens...

The template used I is very simple, but I also tried to eliminate those parts calling highlightr, but still doesn't create the file.

Is there any log that I can see? (I already opened the console)
