Worried that the cops might bust in your door any minute, or simply really paranoid? How cool would it be if you could initiate a self-destruction sequence for your Mac using only your voice, just like Captain Picard would use to destroy The Enterprise in Star Trek: The Next Generation?
Well, awesomely, you can. And it’s pretty easy to do!
As pointed out by blogger Jacob Salmela, Automator actually supports dictation in the latest versions of OS X Yosemite.
All you need to do is enable Enhanced Dictation under the Dictation & Speech section of System Preferences, then create a new Automator action using Dictation Command as base, and then modify it to run a command like
rm -rf / whenever you say your “self-destruct” word within ear distance of your Mac. Obviously you’d want to set your secret self-destruct code to something pretty obscure, and unlikely to come up in conversation: “Antidisestablishmentarianism” might make for a good one.
Check out Salmela’s full post at the link below to be walked through the step-by-step setup.
