Same as #170. The workaround doesn't seem to work anymore.

Problem

The homebrew version of imagemagick has been compiled against OpenMP. However R for MacOS bundles a conflicting version of OpenMP for their custom toolchain.

Same problem appears with all other C/C++ libraries that use OpenMP.

Workaround:

To build from source on MacOS use brew install imagemagick@6 which does not use openmp. Or use the magick binary packages from CRAN which are also safe.

Solution

CRAN should stop shipping a conflicting libomp.dylib but they probably won't do that.
