I had the same problem (it is with the R GUI, Big Sur and a Mac with Touch Bar).
The Mac R GUI: "R-GUI-7903-4.0-high-sierra-Debug" works fine. Those warnings disappeared with this R GUI (with a 16-inch MacBook Pro 2019, Big Sur 11.0.1 operating system and R 4.0.3). You can download the last R GUI at this address: https://mac.r-project.org/ The last version is now the 7905. It will probably work fine too. > El 5 ene 2021, a las 11:05, Univ-Rouen <aurelie.hu...@univ-rouen.fr> escribió: > > Thanks for your response, > I saw the discussion but I hoped that maybe, there would be new solutions… > Regards, > Aurélie > >> Le 5 janv. 2021 à 10:50, Dr Eberhard W Lisse <e...@lisse.na> a écrit : >> >> Aurélie >> >> This has been discussed here on the list recently and I think the >> short term fix is to use Rstudio or R from the command line. >> >> I am sure this will sort itself out over time. >> >> el >> >> >>> On 2021-01-05 11:01 , Univ-Rouen wrote: >>> Dear all, >>> I have change my MacBook Pro since a few months and now, I have a >>> MacBook Pro 16 with a Touch Bar.
