Latest Update Finally Made It Useful Again.

FINAL EDIT: The app now has both a visible scroll bar and a click-and-drag resizable height that fits my number of cores, so I'm happy.


NEW EDIT: Ok, the app finally shows all of my cores again. But it does so through an unintuitive (because there is no scroll bar) scroll view that I'm only able to access using my mouse wheel, that the developer had to tell me about.

But what if I didn't have a mouse with a wheel? Why can't I click and drag? What if I want to see ALL of my cores at once (and I do) while analyzing a program's usage of my processor instead of having to scroll back-and-forth through them? The old view of all 20 cores at once was perfect.

For five stars, this app needs both a scroll bar, and the ability to click and drag a corner to lengthen or widen the view to include all processors.

As for going to the "support page", this page was non-functional. Since it did not provide either an email address, or a simple way to send the developer a message. It demands that I tell it what I need help on first, and I'm not going to waste time with an auto-support rabbit hole in order to send him simple suggestions.

(EDIT: It looks as though the program has been updated, but now it only shows 8 cores, not the full 20 that it showed in the update that came after my last review that criticized it for only showing 16. Come on!!!)

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?

Hi kGoreham,

UPDATE 7Dec2019
I am glad you like the new update. Have a great day there. And all feedback is welcome at

UPDATE 3Dec2019
New version online! In version 1.0.9 you will see a visible vertical scroll bar inside the app window. So when you move your mouse inside this app window, you will see the scroll bar on the right side.
Also, when you have more than 8 threads, you can increase the height of this window.

If you have any further feedback, please let me know on


UPDATE 26Nov2019
No, the search is an option. But if you go to the page. And you scroll a bit down, you can choose the topic "Desktop App". And then "CPU Check", to get the FAQ list and the option 'I'm having a different issue'. If you click on this hyperlink, you can use my contact form.

I appreciate your feedback and concern. Let talk on this direct contact form. I am ready to build this app better.

The latest version should show you the correct core.
If you need any help please use the official support form:
And submit a screenshot of what you see. I am happy to help you. And solve this problem.

The app no longer works in the notification center as of OS 11. Also, the app lacks the ability to show processor frequency. iStat Menus integrated support for Intel Power Gadget to show processor frequency values, which is vastly more useful to me than processor use percentage alone. Otherwise, everything else is marvelous.

Hi pgcrowe,

The latest CPU Check Mac app version 1.0.11 and higher support the new macOS Big Sur widgets. And you can choose up to 7 best widgets, from a single progress bar to a multiple progress bar for each CPU. Or if you want to keep it simple, you can get the total CPU usage in percentage number.

If you like this big update, do not forget to rate this to 5 stars.

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.
