Download them with ``wget --level=1 --cut-dirs=5 --mirror --convert-links --adjust-extension --page-requisites --no-parent https://opensource.apple.com/source/security_certificates/security_certificates-<latest>/certificates/roots/``. Then: ``for f in \*.cer \*.der \*.crt; do echo $f >/dev/stderr; openssl x509 -in $f -inform DER -outform PEM ;done >/tmp/Apple.pem``
