As detailed in https://bugs.python.org/issue33725, starting new processes with 'fork' on Mac OS is not guaranteed to work in general. As of Python 3.8 the default process spawning mechanism was changed to avoid this issue. Spack depends on the fork-based method to preserve file descriptors transparently, to preserve global state, and to avoid pickling some objects. An effort is underway to remove dependence on fork-based process spawning (see #18205). In the meantime, this allows Spack to run with Python 3.8 on Mac OS by explicitly choosing to use 'fork'.
