Fix Mono No certificates found error on MacOS

run.sh

#!/bin/sh

# The error was:
# No certificates found, you can install some with one of these commands:
#     cert-sync /etc/ssl/certs/ca-certificates.crt #for Debian based systems
#     cert-sync /etc/pki/tls/certs/ca-bundle.crt #for RedHat derivatives
# Read more: http://www.mono-project.com/docs/about-mono/releases/3.12.0/#cert-sync

# From here: http://www.mono-project.com/docs/about-mono/releases/4.8.0/#tls-12-support
# The fix was:

curl -L -o /tmp/cacert.pem https://curl.haxx.se/ca/cacert.pem
cert-sync --user /tmp/cacert.pem

Thank you !
