11 months ago As you are installing GalSim through pip (rather than conda), you will need to have fftw already installed (as pip cannot install fftw). See https://galsim-developers.github.io/GalSim/_build/html/install_pip.html#installing-with-pip for details. I think fftw should be available on macOS through brew or macports

Hello, I have tried to install GalSim (actually Romanisim) on my Apple M1 / MacOS 13 but was not successful due to FFTW failure. Do you have any resolution for this issue?
