Yes, the pandemic has made teaching very difficult. As a general matter,
it's been my experience that almost all Rcmdr installation problems are
on macOS. It's usually easy to help students get going in person, much
less so remotely.
Please let me know whether your students solve their problems, and if
so, how, so that I can update the Rcmdr installation notes, if necessary.
Also please keep the conversation on r-help so that others are able to
follow it.
Best,
John
