Every Monday, we'll show you how to do something new and simple with Apple's built-in command line application. You don't need any fancy software, or a knowledge of coding to do any of these. All you need is a keyboard to type 'em out!
If you've ever had an issue with your Mac that only happened when the computer was under stress (or if you just have the sudden urge to give your Mac a stress test), then there's a Terminal command for you. Apple technicians often use the "yes" command to instantly begin utilizing 100% of your CPU and its cores. This is great for when you need to burn in or stress a Mac (or other Unix machine). Let's take a look at how to use it.
One of the big stories from the general tech sphere yesterday centered on Ars Technica's discovery that Samsung artificially inflated the CPU speeds for the Galaxy Note 3, leading the normally Twitterphobic Apple executive Phil Schiller to tweet "shenanigans" in response. But as Anandtech reported today, the rabbit hole goes far deeper than that. According to the site's research, almost all smartphone manufacturers--with the exception of Apple and Motorola--employ GPU and CPU tweaks to cheat on benchmark tests to make smartphones appear more powerful than they are.
