This article will delve deeply into identifying the ‘mds_stores’ process and its functionality. It will also outline some of the necessary steps you need to take to reduce the CPU utilization of the process.
What is the ‘mds_stores’ Process on Mac?
On Mac, “mds_stores” stands for “metadata server,” and it is a process in macOS that simply helps Spotlight Search work more efficiently and faster. It does so by indexing and creating a database of all the files stored on your Mac.
↪ What is Spotlight Search on Mac?
Spotlight Search is the built-in universal search tool used to find files, documents, applications, etc., in macOS. So, mds_stores basically helps Spotlight function more effectively. Without this, the search would have to scan every file on your drive, which could be time-consuming and taxing on the hardware on its own.

Why is mds_stores Consuming High CPU Usage?
Typically, mds_stores runs in the background and doesn’t consume a lot of resources. However, there are times when this consumption could reach upwards of 99.5% CPU usage, making your Mac almost unusable. This could happen for a number of reasons.
How to Fix mds_stores CPU Overuse?
While most of the time, using large amounts of your CPU isn’t necessarily an issue, it’s always good to take precautionary measures just to be sure. For this purpose, your plan of action should be isolating the cause first.
1. Upgrade to the Latest Version of macOS
Upgrading to the latest version of macOS can help to prevent problems with the Spotlight index, which causes mds_stores to use high CPU. When you upgrade to a new version of macOS, the Spotlight index is automatically re-indexed, which can help to fix any problems that have occurred. Moreover, if there is a known bug causing a certain process to chug up those precious resources, Apple would address the problem via an update, so it is important to always be looking out for new updates since most of the fixes are addressed in those.
2. Turn off File Indexing
If updating didn’t do the trick or you are running the latest version of macOS, you’ll probably have to completely disable indexing, and this can be done by turning off Spotlight file indexing using the Terminal commands. Here’s how you do that:
3. Exclude Certain Files from Spotlight Indexing
Excluding specific files from indexing will not necessarily stop the mds_stores process immediately, but it will surely reduce the frequency with which it uses large portions of your processor’s resources.
4. Restart Your Mac
Sometimes, the most complex problems are easily resolved with a simple restart. Most of the times, doing this will clear up any glitches or software issues that may have been contributing to an increase in CPU consumption via mds_stores. Restarting your Mac can help to clear out any temporary files or processes that may be causing Spotlight or mds_stores to use a lot of CPU resources. If your PC is totally unresponsive, hold down the Command (⌘), Control (Ctrl) and Power keys till the screen is blank before the device restarts.
5. Wait for the Indexing to Complete
If you do not want to disable file indexing and are not in a hurry to free up your hardware resources, the best course of action is to simply wait for file indexing to complete. Whenever you add or delete a large number of files or add in any external disks, the Spotlight starts logging the changes. All of this indexing process can take several minutes to sometimes hours on end, depending on the size of your changes or external disks. Once indexing is complete, CPU usage will drop on its own.

Conclusion
The mds_stores process is a normal part of macOS that helps Spotlight Search work more efficiently. However, there are times when it can consume a lot of CPU resources, making your Mac slow down. It’s best to simply wait for the indexing to complete if you believe that the high CPU consumption is not part of a system bug.
