I’m working on a video training series on how to use Termina.app on macOS. I would like to “simulate” typing large blocks of code into the terminal as video visual aids.

I woke up today to find my machine name in .zsh terminal changed. The machine name used to be xxxxx-Macbook-Pro
Upon opening my computer today, I got a message saying something along the lines that the original name was taken, and so the Macbook-Pro-2 is being used.
This is wierd. Any help would be appreciated.
