I am trying to install Hashcat using the instructions on Brew: https://brewinstall.org/install-hashcat-on-mac-with-brew/
When I enter the first command: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null on terminal, it says: Need sudo access on macOS (e.g. the user myname to be an Administrator)!
However, I am already an administrator when I check in Users&Groups in Systems Preferences. Typing sudo whoami
also gives me back root
Can someone please help me out with this?
