I second this request. Dropping OpenMP support in R v4.0 on Mac is unfortunate. My R package is highly parallelized via OpenMP, and many of my end-users take advantage of the excellent speedups. It would be much appreciated if user-level instructions could be provided for how to enable OpenMP support on the Mac.
