Does It’s Job Well… But there is one thing to fix...

Simple app that does what it says. My only complaint is that it only shows up to 16 core threads, and I’m running it on my new 10-core (20 thread) iMac Pro. Can we get please a resize option for the app window?

Works Like a Champ

Simple and to the point. If you want to know how the cores of your CPU are being taxed at certain times, CPU Check will let you know. It’s just like the picture above, works beautifully with the most up-to-date system as of this writing: 10.11.6 (El Capitan). As a Logic Pro X user, it’s good to be able to turn certain things on and off to see what the impact is and how many more processor intensive plug-ins and instruments I might be able to add. I couldn’t be happier with this simple app.
