Beautiful, solves our issue. Was that announced at some point? If so, where? For reference the R-on-macOS FAQ I consulted still talks about 10.13 at https://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html#Installation-of-source-packages CC = clang -mmacosx-version-min=10.13 CXX = clang++ -mmacosx-version-min=10.13 -std=gnu++14 FC = gfortran -mmacosx-version-min=10.13 OBJC = clang -mmacosx-version-min=10.13 OBJCXX = clang++ -mmacosx-version-min=10.13 so someone may want to refresh this. It is what I consulted as relevant info.
