Spotlight begins the indexing process when a user first logs in to their macOS. After wiping the respective SSD, you either buy a new Mac or have a fresh option of macOS. The spotlight will begin indexing immediately once you log in.

The metadata server keeps track of the indexing of files. The metadata server is abbreviated as “MDS“. It’s a procedure that runs in the background on the Mac.

As a result, it can index almost everything on all the files on the SSD. Moreover, it can connect any other external drives you’ve connected to the respective computer.

What Makes mds_stores on Mac Consume Heavy System Resources

MDS stores usually finish indexing quickly. It consumes some CPU resources during the indexing phase. However, once the initial indexing is complete, it uses only a little CPU power.

Unless your Mac has had a lot of data removed and added to it. This method is used to index files. Nevertheless, the time it takes will differ based on the data the computer already has.

It continues to index the files and consumes significant CPU power. In other words, that could lead to mds_stores high CPU usage.

Due to a Spotlight issue in a few rare instances, MDS stores keep the indexing process running for weeks. This has been reported by a large number of Mac users.

Now that you have a basic understanding of Spotlight, its indexing mechanism, and why it uses so much CPU. Finally, we’ll go through all potential solutions for resolving this vexing problem.

Once you have done that, you should hit the “Enter” key to execute the command.

Once you have done that, you will be required to enter your password on the PC. You will need to do it because the system wants you to check if you have administrator privileges. So, just enter the password and proceed.

As a result, Spotlight will be stopped. Once you have done that, with all the other processes, the system will close everything related to this. You can use the computer for some time now and open Activity Monitor.

That will display the processes that consume the CPU resources. Once the Spotlight is closed, mds_stores on Mac will not be there. You can restart the Spotlight feature and see if the error is gone.

If You Don’t Know How to Restart Spotlight, You Can Follow the Steps Mentioned Below.

  • First, you should open the “Finder” option and go to “Applications” as well. After that, you should go to “Utilities” and choose “Terminal“.

  • Once you have done that, you can perform a restart on the MAC and continue using it. You can take a look at the activity monitor now. Then, check if the Mac mds_stores are using extensive resources.

If you still see mds_stores high CPU usage, the reason could be uncompleted indexing. Such scenarios can happen if a huge amount of data is indexed.

So, in such a situation, you can delete some of the directories in the spotlight index. By doing that, you can reduce the size of the index size. Then, mds_stores on Mac might complete the respective indexing process pretty faster.

If You Are Not Know How to Delete Those Directories, You Can Follow the Steps Mentioned Below.

First, you are supposed to launch “System Preferences“. To do that, you can click on the “Apple Menu“. Then, you are supposed to select it from the Launchpad.

  • You should click on the option called Spotlight. You will now see a screen with Search Results & Privacy as two options.
  • Go to “Search Results“, and you can define the categories you intend to view. That means the options that should appear in search results. Also, under “Privacy“, you can add folders you don’t want to index with Spotlight.

Hopefully, this method should work. If not, you shouldn’t worry, and you can proceed to the next method to fix the error.
