Want to freak out your wife/husband/kids?

On a mac that you have access to:

Go to ‘System Preferences’. Under ‘Internet & Networking’ there is a ‘Sharing’ icon. Run that. In the list that appears, check the ‘Remote Login’ option.

Then ssh into your mac remotely by downloading putty if you’re on a pc or launch a terminal on another mac and run “ssh username@ip.address” without quotes to ssh to the mac while someone is working on it.

Once you’re logged in:

Crank up the volume by running:
sudo osascript -e "set volume 10"


Then run:

sudo osascript -e 'say "I am watching you." using "Zarvox"

Or if that doesn’t work, try:

sudo osascript -e 'say "I am watching you." using "Cellos"'

Make sure you have an automatic emergency defibrillator handy.
