# The `find` line is required as a result of https://github.com/actions/runner-images/issues/9966.
# This is a bug in the macOS runner image where the pre-installed Python is installed in the same
# directory as the Homebrew Python, which causes the build to fail for macos-13. This line removes
# the symlink to the pre-installed Python so that the Homebrew Python is used instead.
