Suggested January 2024 Configd: Fixing High Cpu Usage Problems With The Configd Process In Mac Os X

configd is a system configuration daemon that runs behind Mac OS X, most users will never notice or see the core OS X process running in the background of their Macs. With that said, configd can sometimes act up and cause unusual CPU spikes and fan activity making your Mac sound like a wind tunnel. Odd configd behavior is easily diagnosed by launching Activity Monitor, sorting by the “% CPU” option, and seeing the ‘configd’ root user process sitting at the top taking up somewhere between 20-95% CPU. If that behavior lasts for a minute or so it’s usually not a big deal, temporary spikes can be normal so just let it run and ignore it, but there are times where configd can go inexplicably errant and it’ll sit around 50% CPU utilization or more for hours for no obvious reason – that is what we’re looking to resolve here.

Resolve configd High CPU Usage with Force Relaunch via Terminal

We’re going to forcibly relaunch configd by giving it a swift kick in the pants using the all-powerful ‘killall’ command. Because configd is a system process, it will instantly relaunch once it has been killed, and in every instance where configd is going crazy with processor utilization this trick solves the problem.

Launch Terminal (sitting within /Applications/Utilities/ as usual) and type the following command:

sudo killall configd

You’ll need to enter an administrator password to execute the command as super user, thus the sudo prefix. Running the command without sudo is ineffective because the process is owned by root (super user).

If you kept Activity Monitor open and sorted by CPU, you’ll find ‘configd’ disappears and when it relaunches it’s no longer sitting at the top of the list and no longer eating up inordinate amounts of CPU. Searching for the process should now find it consuming somewhere between 0% and 1% of CPU.

If you still have problems with configd after using the killall command, jump to the bottom of this article to learn more about troubleshooting configd issues.

Dealing with configd without Terminal

If you aren’t comfortable with the command line, there are two other options:

Quit all running Mac applications, which you can do manually or by using this self-made app to quit everything in OS X

Reboot the Mac

Rebooting the Mac has the same effect as killing the configd process directly, though it’s obviously a bit more intrusive to your workflow. Quitting every application can help if the configd error is caused by an apps errant behavior, more on that in a moment.

Diagnosing specific configd problems and learning about configd

Apple officially describes configd as follows:

The configd daemon is responsible for many configuration aspects of the local system. configd maintains data reflecting the desired and current state of the system, provides notifications to applications when this data changes, and hosts a number of configuration agents in the form of loadable bundles.

That excerpt is taken from the manual page on configd, which can be accessed by typing the following into terminal:

man configd

You can read that directly on your Mac through the command line, or through the web using the Developer Library link here.

If you want to attempt to diagnose why configd went crazy in the first place, you can look around in the following two locations for configd bundles and plist files, which may provide some hints as to what is going wrong and why:


Another option is to choose to re-run configd in verbose mode with the following command:

sudo /usr/libexec/configd -v

This will export verbose information to the OS X System Console, which can be read either from the Console app or through the command line as well. Comparing that information to what is found in the aforementioned system directories can be very helpful in diagnosing a precise cause.

General experience has shown that some apps and processes cause configd issues more often than others, some of which may include Java and Java based services like CrashPlan, certain printers where there are unresolved printing errors, and improper network configurations where a network connection is repeatedly attempting and failing. This is why sometimes quitting all apps is effective at resolving the issue, because it may end the failing repetition which is causing configd to go haywire, and in some cases where killing configd doesn’t solve the problem then removing the culprits plist file can resolve the issue once and for all. Your individual experiences and results may vary.

If you’re a longtime Windows user, you’ve probably bumped into one or more system processes that tilt CPU to sky limits.

Some are less common, some are almost automatically implemented with the system (Windows Update process in Windows 7).

One of the rare ones that can occasionally take hold of your CPU in Windows 10 is Client Server Runtime Process better known as chúng tôi .

This process is an essential piece of the Windows platform and it usually takes minimal resources. Well, not in this scenario.

Users reported that, upon inspection in Task Manager, they bump into a strange process that takes 80 – 100 % of CPU usage.

It’s fair to say that this is a grave issue, so you’ll need to address it as soon as possible. The solutions we provided below should be helpful, so make sure to check them out.

How can I resolve high CPU activity of chúng tôi in Windows 10? 1. Scan for viruses

Let’s start by addressing the sporadic cause of this inconvenience. It’s fairly rare for system processes to start misbehaving in this manner.

There are indeed various possible reasons why one of the essential Windows services starts hogging on your resources, especially CPU, but most of the time it’s due to an external factor. Or, to be exact, a malware infection of some kind.

Since the scanning procedure differs, taking into consideration all available software, we made sure to explain how to scan your system with Windows Defender.

It’s always there, even if you don’t want it to be, so make sure to check the steps below:

We also strongly recommend using professional antivirus software in order to be sure that any virus threat will be scanned, found, and deleted from your PC.

2. Delete current user profile

Expert tip:

Since Client Server Runtime Process is partially related to a user profile, CPU spikes are nothing uncommon.

Now, the reasons for this unwelcome occurrence are to be found in a malware infection, which tends to corrupt system files or even clones them.

So, even though your PC isn’t infected at the moment, the damage might be already done.

That should be a good enough reason to delete your user profile and try a new one.

Yes, you’ll need to backup your data and reconfigure some minor things, but the problem should be resolved. Here’s how to do it in a few simple steps:

3. Reset this PC

It completely restores Windows 10 to its initial values, while preserving your data in the process.

Of course, you should back up everything from the system partition to an alternative partition, cloud storage, or external storage.

Here’s how to do it and hopefully resolve the issue at hand:

How To Fix Zoom High Cpu Usage?

How to Fix Zoom High CPU Usage? [7 Quick Ways]




Zoom has increasingly become popular since the start of the pandemic in providing remote support to businesses.

While for the large part it has been instrumental in business continuity, it is not without some drawbacks.

If you use Zoom often, it can tax your CPU and cause high CPU usage in browsers.

Struggling with various browser issues? Try a better option: Opera One

You deserve a better browser! Over 300 million people use Opera One daily, a fully-fledged navigation experience coming with various built-in packages, enhanced resource consumption, and great design.

Here’s what Opera One can do:

Optimize resource usage: Opera One uses your Ram more efficiently than Brave

AI and User Friendly: New feature directly accessible from the sidebar

Gaming friendly: Opera GX is the first and best browser for gamers

⇒ Get Opera One

Zoom is a video conferencing platform that is used by millions of people every day. It has an amazing feature set, but there are some limitations to the free version of Zoom. Sometimes you may have trouble detecting your microphone but we have a guide on how you can fix the issue.

Although it is a useful tool for businesses, the Zoom application can be resource-intensive to use and sometimes lead to your browser’s high CPU usage. This can affect both your browser and computer performance. 

When this happens, you may experience slower browsing speed and other issues such as freezing or crashing.

Why is the CPU usage so high in Zoom? 

Zoom uses a lot of CPU because it’s doing a lot of things at once. It’s encoding video and audio, capturing your webcam feed, and running voice recognition software so you can talk with people on the other end of the call.

Other reasons include:

Your computer is low on memory – If you have less than 2 GB of RAM on your computer, it will be difficult to run Zoom without causing high CPU usage. 

The computer hardware is not powerful enough – Zoom is a highly resource-intensive application. You may need a faster processor, more RAM, or a better graphics card if you want to use other programs while using Zoom at the same time.

Background programs – If you have other programs running that are using up your CPU, they could be competing for resources.

Poor internet connection or limited bandwidth capacity – If your internet connection is slow, you may see high CPU usage by Zoom. This is because Zoom uses more CPU power when the connection is slow.

So, What does it mean when your CPU usage is affecting the meeting quality? The Zoom meeting experience is highly dependent on your computer’s performance. For example, if you have a slow computer or low-quality internet connection, you’ll notice that the video and audio are unclear or keep stuttering. 

Quick Tip:

As a practical solution, we present an optimized browser like Opera that offers faster navigation without consuming high CPU resources.

Plus, you have integration features with social apps that allow you to interact on different platforms directly from the homepage.


Connect with your colleagues on Zoom from this light-resource browser.

How do I reduce Zoom power usage?  1. Close unused applications

If you’re having trouble with Zoom’s CPU usage, it’s a good idea to close any other applications that may be open on your computer.

You may be running other resource-intensive applications while using Zoom on your Mac, Chromebook, or Windows 11. If possible, close out any applications that might be using a lot of RAM or processing power such as Microsoft Word or Excel.

The first thing to check is whether or not you have the latest version of Zoom. If you’re running an older version, you need to update your software. Zoom browser 100% CPU tends to occur when running outdated programs.

Expert tip:

3. Use a wired connection

If you have a slow internet connection or are using Wi-Fi, switch over to a wired connection using an Ethernet cable to maximize performance. 

This will eliminate any interference with your network and allow you to connect to Zoom without any problems.

4. Adjust video quality 

If you are using a high-resolution video stream (such as 1080p), this will consume more resources from your computer than if you were using a lower resolution stream (such as 720p).

The lower the quality, the less processing power it uses. If you’re having issues with high CPU usage when using Zoom, try lowering the video quality first.

6. Use the web version

If you have an older device or one that doesn’t have a lot of processing power, this can cause issues with making audio and video calls. To avoid these issues, use the browser version of Zoom instead.

The browser version of Zoom uses significantly less CPU than the desktop application because it doesn’t have to render graphics and audio locally.

7. Upgrade your computer hardware

If all else fails, it may be time to upgrade your computer hardware. Running a very old version of Windows may be the root cause of the problem.

Most applications are usually updated to function well with the latest operating systems. If you are using Windows 10, it may be time to upgrade to Windows 11 and see if the problem persists.

How do I turn off hardware acceleration in Zoom? 

Some computers have a setting that enables hardware acceleration for the video and display functions. This can cause problems with video games and other software, including Zoom. 

To disable hardware acceleration in Zoom, follow the steps below:

And that’s how to efficiently manage Zoom’s high CPU usage on your browser. Should you encounter any other related problems such as Zoom video not working, refer to our comprehensive guide for quick fixes.

How To Spoof Your Mac Address In Mac Os X

A MAC address is a unique identifier assigned to your network card, and some networks implement MAC address filtering as a method of security. Spoofing a MAC address can be desired for multiple reasons, and it is very easy to spoof your MAC address in macOS Monterey 12, macOS Big Sur 11, macOS Catalina, macOS Mojave 10.14, macOS High Sierra, Sierra 10.12, El Capitan, Yosemite 10.10, Mac OS X 10.4, 10.5, 10.6, 10.7, OS X 10.8, and OS X 10.9. For the purpose of this article, we are going to assume you want to spoof your Mac’s wireless MAC address, meaning your wi-fi card.

Without further ado, here’s a three step process on how you can spoof and change the MAC address in macOS and Mac OS X.

1: Get the Current Network Interface 2: Retrieving your current MAC address

You’re going to want your current wireless MAC address so you can set it back without rebooting. Launch the Terminal app and type the following command:

You’ll know see something like:

ether 00:12:cb:c6:24:e2

And the values after ‘ether’ makeup your current MAC address. Write this down somewhere so you don’t forget it. If you do, it’s not the end of the world, you’ll just have to reboot to reset it from a change.

Note, it’s possible that your Mac has the wi-fi card on en0 or en1, so you may need to adjust the string according to your network interface as detailed above.

Spoofing a MAC address in MacOS

To spoof your MAC address, you simply set that value returned from ifconfig to another hex value in the format of aa:bb:cc:dd:ee:ff. You can generate a random one if need be.

For this example, we will set our wireless MAC address to 00:e2:e3:e4:e5:e6 by issuing the following command:

sudo ifconfig en1 ether 00:e2:e3:e4:e5:e6

If the wi-fi interface is en0 the command would be like this instead:

sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx

The sudo command will require that you enter your root password to make the change.

Again, you need to make sure your network interface is identified correctly, so if you run into any issues you can confirm that wi-fi is using en1 or en0.

Verifying the Spoofed MAC address worked

If you want to check that the spoof worked, type the same command as earlier:

Now you will see:

ether 00:e2:e3:e4:e5:e6

Meaning your MAC address is now the value you set it to. If you want to further verify the spoof, simply login to your wireless router and look at the ‘available devices’ (or attached devices) list, and your spoofed MAC address will be part of that list.

If you want to set your MAC address back to its real value, simply issue the above ifconfig commands with the MAC address that you retrieved in step 1. You can also reboot your Mac.


other readers point out that Dee Brown’s trick works in 10.5.7 and above too. Thanks Dee!

Update: If you’re still having problems with MAC address spoofing in Leopard or Snow Leopard, the above method still works but try disassociating with any wireless network BUT keep your wireless Airport on (as mentioned above) – an easy way to do this is to type the following in the command line:

airport -z

Note that you have to have the ‘airport’ command setup to work for users, you can do that by copy and pasting this command into the Mac Terminal:

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport

Once disassociated from the network you should be able to spoof your MAC address as usual

Updated 2/28/2012: For Mac OS X Lion, the Airport interface is now called “Wi-Fi” and thus the command to spoof a MAC address in OS X 10.7, OS X 10.8 Mountain Lion, and OS X Mavericks, is:

sudo ifconfig en0 Wi-Fi aa:bb:cc:dd:ee:ff

For some computers Wi-Fi may be the interface but you spoof by specifying “ether” instead.

sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff

Remember to disassociate from any network beforehand with “airport -z” while keeping the card active. If you continue to have problems or receive a “bad value” message, try turning the wireless NIC off and on again using the following:

sudo ifconfig en0 down

Now re-enable the NIC:

sudo ifconfig en0 up

Then proceed to spoof the MAC address:

sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff

Reenabling the network card may cause it to join the last available wireless network.

The MAC address should stay spoofed until reboot, but you can always check what your MAC address is in the GUI or command line with networksetup -listallhardwareports if you’re curious about the current status.


Watch Network Traffic In Mac Os X Via Command Line With Nettop

nettop has a wide variety of uses, but it can be particularly helpful when trying to determine what is using the Macs internet connection and networking interfaces, what is communicating with what and how much data is being transferred, and it’s also just a great utility for network troubleshooting. Command line tools aren’t for everyone though, and for users who would like to view similar network information in a more traditional OS X app format, the free Mac app

Using nettop to Monitor Network Traffic & Connections

Mac OS X includes an excellent command line network utility called “nettop” that allows users to monitor all network activity, traffic, and routes from a Mac to the outside world, both through local (LAN) and wide area (WAN) connections. If you’re unfamiliar with networking tools like this, you can think of nettop as a network centric task manager, displaying active networking connections, sockets and routes, their respective names and process id, the state of the connection and whether the connection is established, waiting, or listening, and information about individual process data transfer. It’s a bit like the standard ‘top’ and ‘htop’ commands which show process and resource information, but rather than showing CPU and RAM usage, it will show live network transfer information like packets sent and received, packet size, and total data transferred.nettop has a wide variety of uses, but it can be particularly helpful when trying to determine what is using the Macs internet connection and networking interfaces, what is communicating with what and how much data is being transferred, and it’s also just a great utility for network troubleshooting. Command line tools aren’t for everyone though, and for users who would like to view similar network information in a more traditional OS X app format, the free Mac app Private Eye is an excellent GUI tool that provides similar information.

Getting started with nettop is easy enough. Open Terminal from /Applications/Utilities, and at the command prompt, type “nettop” to immediately see active network connections and traffic:


Use the down arrow key to scroll down and you’ll soon start to identify processes that you’ll recognize by name, coinciding with apps or processes that are currently in use.

To see the most amount of information, you’ll want to increase the size of the window as large as possible, hit the green maximize button and consider decreasing the font size of the terminal window if you can’t see all that you want to. Hitting the “p” button to put the output displayed by nettop into human readable format is also very helpful for most of us.

Once in nettop you can adjust the output a bit to see more or less information for specific processes and their network communications. Basic nettop commands are:

p – changes to and from human readable format (i.e.: kilobytes and megabytes rather than pure byte count)

d – show delta count (i.e.: active change in packet count rather than total packets

Up & Down arrow keys – navigate up and down in the list

Right & Left arrow keys – expand or collapse specific process or routing groups

q – quit out of nettop

Formatting is easy to follow, despite what the pasted sample block looks like below:

You can also use nettop to just view routing table information if you don’t want to see specific sockets and processes

nettop -m route

The routing information will show the connections from hardware to destination IP, for example, you may see en0 (wi-fi) to the local network IP to a remote server, and you will also see loopback information.

Using the -m flag you can also limit nettop to only show TCP or UDP sockets, with nettop -m tcp and nettop -m udp

There are other ways to see similar information from the command line, including lsof, open_ports, and then, branching away from the command line a bit you can use GeekTool with lsof to have a list of live network connections printed directly over the OS X desktop wallpaper.

For the mobile world with iOS, you can find some similar information with the free networking scanning Fing app, it’s quite a bit more limited but still useful enough to have around on the iPhone and iPad.
