There are two ways to address this problem. usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin The issue that many are likely to face is the /usr/bin comes before /usr/local/bin in their PATH variable which is where the new SSH client will be installed. By default the system SSH client is installed in /usr/bin/ssh. Now that we have OpenSSH installed using Homebrew we need to make sure it is the default SSH client.
