Eberhard, Thanks - I'm also an RStudio user, but am trying to use Rcmdr as a gentle introduction to R for a course (building up to RStudio use later).<br class="">

John, thanks also for responding (not at all an Rcmdr issue, I think - that's just what happened to show the problem).<br class="">

I of course have an interest in getting the Rcmdr to work well on all platforms. Most problems are on macOS. It's hard, however, to address an issue that I can't observe, and I've never seen this one.

As I would have guessed, your new Mac has more horsepower than my relatively old one, so other things equal it should probably display dialogs more crisply.<br class="">

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?<br class="">

I wish I knew, but it's rather strange that the problem went away by itself.<br class="">

<br class="">
To be clear, I never thought that you were hallucinating. It would be nice to know why the problem occurs so that, depending on the nature of the explanation, I could potentially advise users to avoid it. In particular, did you ask your students to reboot their
Macs and try again?<br class="">

Dear all,<br class="">
<br class="">
I’m relatively new to MacOS and have only recently started trying to use XQuartz to enable me to run Rcmdr. Are there any common issues/ tips for getting good performance out of it (or should it usually run well with default settings)?<br class="">
<br class="">
On first installation, I found there was a very long lag in menus being populated (i.e. the menu shape was generated, but no usable options were added), to the extent that Rcmdr was then effectively useless (not Rcmdr’s fault, I don’t think). One of my students
suggested reducing Output Colors option from the default “Millions” setting. That seems to deal with the problem, thankfully.<br class="">
<br class="">
Is that typical of XQuartz, and is there anything else I should be doing to get the best performance from it?<br class="">
</blockquote>
<br class="">
I haven't observed the problem you describe on my Mac, which is a three- or four-year-old MacBook Pro (that is, the Rcmdr dialogs display reasonably crisply for me), and I haven't done anything special to configure XQuartz. Here are the specs for my Mac:<br class="">

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?<br class="">
