My Mrs is an Astrophysicist and she is exactly the same. In her case she is terrified that Apple will move stuff around and break her paths rendering her EMacs setup unusable. Curious to know how to manage all her pipelines, iraf, python, R, Fortran and general fits processing and sundry as well without it breaking every. Single. MacOS. Upgrade. She only upgrades OS’s every time her funding gets her a new machine. Which is infrequently. Like every three years or so. She uses MacPorts.
