How to Fix: Mds_stores Process Consuming High CPU on Mac

We all like it when our computers are working smoothly and without any irritating issues to contend with. However, we do sometimes run into issues with our technology products, just like we do with any other technology product. These problems are typically depressing.

These problems affect everything from our hardware to our software. On rare cases, we come across software issues that have an impact on the hardware, such as the mds stores problem on the Mac and excessive CPU utilisation.

When this problem happens, you will no longer be able to enjoy the fluid browsing that you were used to, and your computer will significantly slow down. The majority of the time, your system overheats, increasing the strain on your cooling fan.

If you find yourself in this situation, don’t be concerned; this article will teach you how to resolve that irritating issue, but first, let’s learn more about it.

What is the mds_stores process? 

A background process known as mds, which stands for MetaData Server, is often connected with the Mac’s Spotlight feature. While it is undeniably beneficial, the mds stores process sometimes goes above and beyond its intended purpose, using 90 percent to 100 percent of the CPU process and causing your Mac to slow down needlessly as a consequence of the extra load.

What occurs is that Spotlight by default makes searching on your Mac computer simple; what it does is that it indexes all the data stored on your hard drive with the aid of three processes: the mds, the mds stores process, and the mdworker process. As a result, with a simple search on Spotlight, you may quickly locate everything you are looking for.

Why does it take long to index?

We can all agree that Spotlight is a one-of-a-kind and indispensable feature of the Mac, and enabling it to continue to operate is perfect. However, it is inconvenient when a supposedly background activity prevents you from doing any action, so will we allow it to prevent us from using our computer entirely? No.

By default, the indexing process should take between 15 and 45 minutes; however, the length of time it takes will vary depending on a number of criteria, which will be discussed more below. Checking the Spotlight icon, which is generally found in the top right corner of the menu bar, will let you know whether MDS and Spotlight are currently indexing. Spotlight is represented as a magnifying glass.

If you see a dot in the middle of the Spotlight symbol, this indicates that indexing is taking place. When you click on it, Mac will display the index duration for you to see.

What makes the mds_stores on Mac to consume a high CPU? 

You can configure the Spotlight index to start manually or automatically. However, it usually comes on when you restart your computer. The spike is often due to large deletion or addition of data on your hard drive. 

You could be having this considerable spike when Spotlight is indexing locations and folders you likely won’t need, such as your TimeMachine’s backup. It could also increase CPU usage when an app or multiple apps are continually changing some folder contents. 

  • Hard disk size
  • Size of your directories
  • Last date Spotlight indexed your device
  • Your Mac’s speed

You can confirm the high CPU usage by launching your Activity Monitor. You should see the amount of resources mds_stores on mac uses, now proceed to the part for solutions. 

How to fix the mds_stores process error

The sooner you address the problem, the better; if your computer’s CPU resources are overloaded, it may become useless, freezing, deteriorating, malfunctioning, hanging, and failing to react to orders, among other things. If the problem continues, your Mac may overheat and the fan will continue to run, which is not recommended. You may choose from the following options:

  • Reboot your Mac
  • Disable Spotlight
  • Temporarily stop and restart Spotlight
  • Reduce Spotlight indexing data

Most of the answers on this page may need Administrator authorization, which will be requested by asking your Admin Password. In the event that you are presently logged in as a guest account, you should switch to the Administrator account immediately.

 1. Reboot your Mac

Many difficulties, including the mds stores process on Mac, have been known to be resolved by rebooting the computer. If you detect any of the symptoms of the mds process problem and can confirm it using the Activity Monitor, your first line of defence should be to restart your computer.

Restarting your computer is as simple as following the normal procedures. When you return to the computer, check the Activity Monitor to see whether the massive resource use has been decreased; if the issue continues, go to option two.

 2. Disable Spotlight

mds, mds stores, and the mdworker processes are all background processes that are coordinated by Spotlight, therefore removing Spotlight should resolve the problem.

  • The Finder application may be found and used from your computer’s Desktop menu.
  • To make the Applications folder larger, select it and then click on it.
  • To access the applications in the utility category, go to Utilities > Utilities.
  • To start the Terminal application, just click on it.
  • The following command should be used in the terminal: sudo mdutil -a -I off, followed by the Enter/Return key.
  • When asked, type in your Admin Password to complete the process.
  • To continue, press the Enter/Return key once again.
  • Check to see whether the mistake continues to occur.

Spotlight may be enabled by repeating steps 1 through 5 above, but this time inputting the command sudo mdutil +a -I on, and then following the rest of the instructions on the screen.

 3. Temporarily Stop and Restart Spotlight

It is possible to temporarily disable Spotlight from running; this is different from the approach described above, but it still requires Spotlight.

  • Launch your Finder application and choose the Applications section from the drop-down menu.
  • Select Terminal from the Utility applications on your device.
  • Press Enter after entering the command sudo launchctl unload w/System/Library/LaunchDaemons/com.apple.metadata.mds.plist and then press Enter again.
  • Press the Enter key after entering your Admin password in the given space.
  • Restart your Mac and check to see whether the problem still exists.

To restart Spotlight 

  • Launch Finder app > Applications > Utilities and select Terminal
  • Type in sudo launchctl -w/System/Library/LaunchDaemons/com.apple.metadata.mds.plist then hit Enter
  • Input your Admin Password in the field provided. 
  • Go ahead and restart your machine and check the Activity Monitor if there’s an improvement. 

 4. Reduce Spotlight indexing data

If the issue remains after attempting all of the remedies listed above, we should minimise the amount of data stored in Spotlight’s indexing. It is our intention to remove several folders and places from the Spotlight indexing in this section, however first, we will;

  • Delete Spotlight database 
  • Re-index the Spotlight database 
  • Prevent Spotlight from indexing some locations and folders

Conclusion 

Despite the fact that we did not anticipate any of the difficulties that we encountered, we were able to resolve them without having to take our Mac to an Apple store. The mds store on the Mac is critical to the operation of our devices.

However, when it starts consuming too much CPU resources, we may need to either Reboot our Mac, Disable Spotlight, Temporarily stop and restart Spotlight or Reduce Spotlight index data. Please make certain that you follow the directions to the letter and that you share with us how you resolved the mistake. Thank you for taking the time to visit.
