I think it is a MacBook Pro issue. I’m using a MacBook Pro (15-inch, 2018), R 4.0.3, MacOS 11.01 and it happens whenever R GUI accesses the Touch Bar, with fix() or load() in particular.
<div class=""><br class="">
</div>
<div class="">Unfortunately, I assumed it would go away so I didn’t take careful notes when I first saw, but I think it started happening with the final versions of Catalina and R 4.0.2. I googled the error message at the time and count find anyone else reporting
it.</div>
<div class=""><br class="">
</div>
<div class="">As far as I can tell the error is benign, the Touch Bar still works and there is no degradation in performance.</div>

<div class="">After a bit of git and google poking it seems this is happening to users<br class="">
of MacVim (<a href="https://github.com/macvim-dev/macvim/issues/1114" class="">https://github.com/macvim-dev/macvim/issues/1114</a>) and a few<br class="">
other FOSS projects.<br class="">
<br class="">
In various GH issues (like that one) the issue claims to be resolved by<br class="">
using the latest Xcode & SDK but that’s not likely to be a solution for R<br class="">
GUI (which I’m assuming you're using and where this error is coming up).<br class="">
<br class="">
Some of the threads I saw made it seem like it was happening especially on<br class="">
Touch Bar-equipped MacBook Pros (but that’s not confirmed).<br class="">
<br class="">
When I try R GUI on Big Sur (on the new M1 Mini) — either just plain R<br class="">
scripts or plotting — I do not see this, nor do I see this on my Intel<br class="">
MacBook Pro (both are on the latest Big Sur beta and R 4.0.3).<br class="">
