Although I cannot reproduce the installation problem on my local macOS and Ubuntu server, it may arise from gfortran not installed on your mac, which is required for installing Rcpp and RcppArmadillo. Please install gfortran installer first and restart R. The recent gfortran version can be obtained from https://gcc.gnu.org/wiki/GFortranBinaries.
