I'm new to Mac OS, and still trying to find my way around. This evening I was working from home, and needed to ping one of our servers. For love or money, I couldn't find a command prompt (equivalent). After search on Google, results shows it should be in Applications \ Utilities and Network Utility. Well, on my MacOS Sierra 10.12, that isn't the case. I had to search deep in the System folder. Once found, I placed an icon on my desktop. But, what is the better way to find apps like this?
