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

Also that very first use may involve more system preparation to generate the font cache, so it may run more slowly until that is complete. I'm inclined to think one or both of these explanations underlay the issues and that we can mark this as User Error, but Resolved!

So I wouldn't be surprised if that was actually happening, unrelated to any setttings. If you start XQuartz later after the cache has been built, it will work fine immediately. So if that is what it was, the issue should not re-occur if you were patient enough the first time.

>> John, thanks also for responding (not at all an Rcmdr issue, I think - that's just what happened to show the problem). Tech details:

>> 2.6 GHz 6-core Intel Core i7
>> 16 GB 2400 MHz DDR4 memory

>> R 3.6.3, new download of Rcmdr etc (reinstalled everything from scratch before realising X11 was the reason Rcmdr wasn't working and downloading XQuartz). I'm almost certain I would have rebooted before trying to run this - I saw that warning somewhere (CRAN FAQ maybe?). I certainly have since, but perhaps that's why it is now appearing to function correctly? I should say that 2-3 students have reported the same problem over the last 3-4 days, so it isn't just me.

One of my students suggested reducing Output Colors option from the default “Millions” setting. That seems to deal with the problem, thankfully.

>> It might help to have some more information. I assume that you're using the most recent versions of R, the Rcmdr package, and other packages, and a recent version of macOS. What Mac do you have, and did you reboot it after installing XQuartz? If you updated R, did you reinstall XQuartz?
