Uninstalling Mono on Mac OS X

remove-mono.sh

#!/bin/sh -x

#This script removes Mono from an OS X System.  It must be run as root

rm -r /Library/Frameworks/Mono.framework

rm -r /Library/Receipts/MonoFramework-*

for dir in /usr/bin /usr/share/man/man1 /usr/share/man/man3 /usr/share/man/man5; do
   (cd ${dir};
    for i in `ls -al | grep /Library/Frameworks/Mono.framework/ | awk '{print $9}'`; do
      rm ${i}
    done);
done

Look at this script https://github.com/gurza/cli-toolbox/blob/master/dotnet/mono-uninstall.sh

Thanks. I can't remember why I was interested in this. I think I had installed Visual Code for Mac and that caused me issues building something else. The pain and memory have been cleared from memory. Thanks for letting me know about this.

Modern instructions are simpler it seems:

sudo rm -rf /Library/Frameworks/Mono.framework
sudo pkgutil --forget com.xamarin.mono-MDK.pkg
sudo rm /etc/paths.d/mono-commands

@king-of-poppk thank you sir, just save my day !
