<p><span style="font-size:13.0pt;color:black">I had similar issues when I installed FLASH 4.8 on macOS Sequoia version 15.3.1. I uninstalled OpenMPI, HDF5, and Hypre, then reinstalled OpenMPI from Homebrew and Hypre and HDF5 (with OpenMPI support) from source.
Make sure that when you configure Hypre and HDF5, you specify the correct path for OpenMPI.<o:p></o:p></span></p>
<p><span style="font-size:13.0pt;color:black">Mine is working now without any issues. I don’t know if this will be helpful to you, but I wanted to share it.<o:p></o:p></span></p>
