How to Fix Mds_stores Process Consuming High CPU On Mac

If you own a Mac or any operating system, you should be aware of how annoying it is when your system starts to stutter and slow down. Because it not only affects your productivity but, in some cases, directly affects the health of your device as well. 

Now, although there could be many reasons behind it slowing down in most cases, it is a process that is running in the background consuming a high CPU which is, in turn, slowing down your computer, making it barely workable at best.

In this article, we will discuss one of them and see how you can fix the mds_stores process consuming high CPU on Mac.

What is Mds_stores

Before we start discussing solutions, let’s first discuss what exactly mds_stores is and what it is used for. Mds or metadata server is an internet process that allows users to search for different files on the system, including any kind of documents, images, and other local files.

It executes this job by recording and tracking all the information about the current data on your system. Once it has all the information, it compiles it and then utilizes it to speed up the search feature available on the Spotlight.

In its absence, each time you search, Spotlight has to one by one go through all the files available on your hard drive, which can take an extended amount of time.

How to Know if Mds_stores Process Consuming High CPU

Although there could be numerous reasons that can slow down your Mac’s speed, if you suspect mds_stores to be the culprit, it’s better to make sure that it is actually the source of your issues. Luckily it can be done simply by checking the Activity Monitor.

In case you aren’t aware of this application, you can use the following steps to access it:

  • Navigate to your Launchpad and type Activity Monitor in the search bar.
  • Open the application, and start looking for processes with high CPU usage in the Process Name column.

In case you don’t see any process named mds_stores, then it is probably not the reason behind your Mac slowing down. But just to be sure, simply type it in the search bar on the top right corner of the Activity Monitor window to check its current CPU usage.

If the usage is above 50%, then there is a chance that it is affecting your Mac’s performance. On the other hand, if it utilizes the majority of your CPU, like 90%  or more, then you definitely need to take measures to tone it down or even eliminate it.

Just ensure that you are correctly shutting it down and waiting for it to finish instead of just shutting off the power completely.  This is because it will allow the system to finish all of its unfinished business, increasing the chances of lowering mds_stores CPU usage.

3. Restart Spotlight

Since mds_store is in a direct link with Spotlight, if you run into any issues with Spotlight, it will directly affect the mds_Store too. Luckily, it can be resolved most of the time by simply restarting Spotlight. To do this first, monetarily stop Spotlight and then restart it. 

Here’s how you can stop it.

  • Head to the Finder app and then to the Applications window.
  • Navigate to the Utility app section and then open Terminal

  • Enter the Admin password in the required field and tap Enter.
  • Now finally, restart your Mac.

To restart your Spotlight, follow these steps:

  • Open the Finder app and then head into Applications.
  • Click Utilities and select Terminal.
  • Paste the following commands “sudo launchctl -w/System/Library/LaunchDaemons/” and press Enter.
  • Insert your Admin password into the required section and tap Enter.
  • Finally, restart your Mac!

Once this is finished, head back to Activity Monitor and check whether mds_stores process consuming high CPU or not. In case it didn’t move on with the next step.

4. Limit Spotlight

If you are using a Mac daily, it is not uncommon that it has thousands of files and folders, and Spotlight forces mds_stores to go through all of them. But you can lower the burden on mds_stores by restricting it from searching unnecessary folders.

To do this, you can follow the following three steps:

Step 1: Delete Spotlight Database From Mac

  • Head to Finder and open Applications.

Effective immediately, you have deleted all Spotlight Database from your Mac.

Step 2: Re-Index Your Spotlight’s Database

Once you are finished deleting your data, simply restart your Mac, and Spotlight will automatically start re-indexing all of your databases on your hard drive. Just remember the process can take some time to finish, so make sure your Mac is connected to a power outlet.

Step 3: Restrict Spotlight From Searching Certain Folders and Locations

Once you finish the first two steps, it is time to restrict them from specific locations. Here’s how you can do it:

  • Head to the Desktop Menu and open System Preferences.
  • Click Spotlight and open the Privacy tab.
  • Now simply drag and drop all the folders you want to restrict Spotlight from searching (it should include folders like Dropbox, Crashplan, ViberPC, CrashReporter, MobileSync, etc.)

Now the system will prevent Spotlight from searching all of these folders. Finally, check the Activity Monitor to ensure your CPU usage has decreased.

5. Disable Spotlight

If any of the above methods does not fix mds_stores process consuming high CPU, you might have to disable Spotlight altogether. Here’s how you can do it.

  • Navigate to Launchpad, and type Terminal in the search bar.
