I followed an installation video for installing Rcmdr on Mac OS and received the following error message after installing the Rcmdr package and choosing a CRAN mirror. I am using R GUI version 4.0.2. I am new to the software and am unsure what the issue is here. Any advice is appreciated.
Edit: I also have just updated the software to the newest version and the problem still persists.
