I'm curious why he did it. To impress people who work at the apple store? OK, ma...

I just read this on Wikipedia (https://en.wikipedia.org/wiki/Yes_(Unix)#Uses):

> In 2006, the yes command received publicity for being a means to test whether or not a user's MacBook is affected by the Intermittent Shutdown Syndrome. By running the yes command twice via Terminal under Mac OS X, users were able to max out their computer's CPU, and thus see if the failure was heat related.

Ahh interesting, maybe he did have a legitimate reason for it.

I always assumed it was busywork to make the customer feel better.

Now if I could just prove to Apple that my computer randomly shuts down all the time... problem is, it doesn't appear to be heat related.

Mine just freezes, the last 0.3 second of sound is just repeated until it reboots by itself.

For reference, I had that exact same issue on my MBA - went on for years. Many times while watching youtube or doing something Garageband related.

At the time I had 10.11 on it, but that OS had itself been upgraded from 10.10.

When 10.12 came out, I decided to install fresh - so I backed everything up and installed onto a new SSD drive. The issue has now gone away completely....

Funny, I've seen that multiple times on my homebuilt Fedora system.

You know the system keeps logs, right?

Open console.app and look at the timestamp of log files when the crash occurred.

Hm, my old Dellbuntu laptop does the same. It's been dropped a few times in its 10 years of service, and now sometimes will shut down if I tap it too brusquely, regardless of the temperature. The BIOS will report it overheated, and i don't know what's going on.
