Dear Niall,
I'll update the Rcmdr macOS installation notes to reflect Simon's information about \
XQuartz causing a font cache to be built on first installation.
I'm glad that the Rcmdr is now working normally for you and your students. I wouldn't \
code this as "user error," but as a previously unnoticed (by me) consequence of \
installing XQuartz for the first time.
Best,
John
