Question: Q: high cpu usage even without apps running Dear Guys and Gals, I am experiencing a strange problem, my computer was incredibly slow in the last days, after a little troubleshooting, I decided to simply format everything and proceed with a new, clean system. See real-time CPU, network, or disk status in the Dock. It’s easy to keep an eye on your system status without even looking at the Activity Monitor window—you can monitor your CPU, network, or disk usage as a live graph right in the Dock. How to see your system status in the Dock. To explore the Activity Monitor User Guide, click Table of Contents at the top of the page, or enter a word or phrase in the. Use the fsusage command line to trace SymDaemon file activity instead. To install Instruments, you must install Xcode, the Macintosh development tools. Xcode is free and can be obtained via the following means: The Mac App store (in Mac OS X 10.6.8 and later - requires registration with the App Store).

Most of the time, the processor on your Mac uses only a small percentage of its processing power. When you use apps that require intensive calculation, the processor uses more of its capacity. View CPU activity on your Mac in the Activity Monitor window.

To enable viewing in the Dock, choose View > Dock Icon, then select the Show CPU option you want to view.

In the Activity Monitor app on your Mac, do any of the following:

  • To view processor activity over time, click CPU (or use the Touch Bar). The following percentages appear in the bottom of the Activity Monitor window:

    • System: The percentage of CPU capability that’s being used by processes that belong to macOS.

    • User: The percentage of CPU capability that’s being used by apps you opened, or by the processes opened by those apps.

    • Idle: The percentage of CPU capability that’s not being used.

  • To view current processor activity, choose Window > CPU Usage.

  • To view recent processor activity, choose Window > CPU History.

  • To display more columns, choose View > Columns, then choose the columns you want to show.

I prefer SystemPal. IStat itself consumes too much CPU and RAM. SystemPal is quick, tiny, configurable, neat, and powerful. It's available on Mac App Store. Firefox is is a multi-threaded app. App Cpu Usage Mac Os; Cpu Usage Define; This problem occurred to me when I was contributing with [email protected] project of Stanford University. Their application (also known as fahclient) was using all my computers CPU and the temperature of my Mac’s graphic card was around 89 degrees centigrade.

Why wouldn’t you want to know what’s going inside the center of your Mac? Yes, you want it. Download CPU Usage Meter Pro for macOS 10.8 or later and enjoy it on your Mac. ‎CPU Meter New is a small application which resides on your status bar and provides useful information about your computer's processor usage, allowing you to optimally utilize your PC resources.

This problem occurred to me when I was contributing with [email protected] project of Stanford University. Their application (also known as fahclient) was using all my computers CPU and the temperature of my Mac’s graphic card was around 89 degrees centigrade. So I tried to limit the CPU usage of this application within it’s preferences menu, but it was not working at all, so I searched Internet and I found that this is a common problem an the solution was not that well-known ! So in this post I’m going to describe how to limit application CPU usage in Mac OSx. In this tutorial I’m going to use cputhrottle which is a small OS X command-line utility designed to limit the CPU usage of a process to which it attaches.

First of all I should say that I used this solution for OSX 10.8.3 and it is working perfectly.
These are the steps you should go through to get this done:

  1. Download cputhrottle application
  2. Almost setup the cputhrottle application
  3. Limit the process using cputhrottle

1. Download cputhrottle application

In this step you should download the cputhrottle from it’s website:

You have two option to download, but I prefer the binary version (cputhrottle.gz), and I’m describing the binary version in this tutorial.

>>> Update: the willnolan website is down at the moment, <<<<
>>> so you can download the application from the link below <<<<

2. Almost setup the cputhrottle application

First open the terminal and navigate to your download folder, in my case:

You can follow the instructions from it’s website and I’m just copying those instruction here:

You must run “chmod +x cputhrottle” after running “gunzip cputhrottle.gz”, in order to make the program executable. Otherwise, it will not start correctly. Some folks have noted that gunzip says that the file is not in gzip format. In that case, try renaming the file to “cputhrottle” and running as-is.

In my experience, I got the gzip error:

gzip: cputhrottle.gz: not in gzip format

so I just renamed the file by the following command:

Then it is time to set the execution permission for this file:

3. Limit the process using cputhrottle

Mac Os Cpu Usage

What is best version of microsoft office for mac. This step is the only step you should do whenever you want to limit some process CPU usage. first use the following command to get the PID of your desired process:

which will result this:

PID COMMAND %CPU TIME #TH #WQ #PORT #MREG
13004 top 5.4 00:01.80 1/1 0 24 31
13000 mdworker 0.0 00:00.05 3 1 55 66
12983 LKDCHelper 0.0 00:00.00 3 1 34 45
12981 com.apple.iC 0.0 00:00.08 4 2 55 67
12980 taskgated 0.0 00:00.03 3 1 31 60
12897 ocspd 0.0 00:00.11 1 0 25 45
12870 mdworker 0.0 00:03.48 4 1 57 95
12842 bash 0.0 00:00.01 1 0 21 26
12841 login 0.0 00:00.02 2 1 33 67
12837 cputhrottle 0.1 00:02.80 1 0 17 22
12789 FahCore_a4 200.3 15:15.36 5 0 26 205
12786 FAHCoreWrapp 0.0 00:01.29 2 0 23 74
12782 FAHControl 0.5 00:23.38 6 3 104 354

You can also use the following command to see the most demanding running processes in your computer:

so now finding the PID is not hard due to the massive amount of CPU usage. In this case the file named FahCore_a4 is using 200.3% of my CPU and the PID of it is 12789. So I use the following command to limit it’s CPU usage to only 25%:

So in the command above, the first number is the PID of your desired process and the second number is the percentage you want this process to use.
The only step left is typing your administrative password because you used sudo command.

4. Optional step – Keep the software running

As you can see in the comments, some users face this problem that the cputhrottle terminated out of sudden after few hours of running and their cpu usage were uncontrolled after that, so one of the folks was kind enough to write a shell script to check the status of this software and run it again if it was terminated.
The shell script can be accessed from Maui’s githup:

Just get the code and put it in the same directory as cputhrottle, then open it in you favorite text editor (I personally use nano)

Now you can configure the settings you like, then you should set the permission so that the code can get executed:

and now everything is good to go and you should run the shell code so it do it’s job:
