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 firstname.lastname@example.org” 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"
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."
Make sure you have an automatic emergency defibrillator handy.
