Corespotlightd uses high CPU because it’s indexing files for Spotlight search. This can happen after system updates or when many files are added or changed. To fix it, rebuild the Spotlight index or limit which files are indexed.
I once faced the corespotlightd high CPU issue after a macOS update. My Mac slowed down until I rebuilt the Spotlight index, which helped reduce the CPU usage significantly.
In this article we discuss about “Corespotlightd High CPU”.

Introduction
If you’re a Mac user, you’ve likely experienced times when your system feels sluggish, and the fan runs at full throttle. One of the common culprits? The corespotlightd process. You may have come across this in your Activity Monitor, eating up a large chunk of CPU resources. But what exactly is corespotlightd, and why is it causing your Mac to slow down?
What is corespotlightd?
Corespotlightd is a background service on macOS responsible for indexing your files for Spotlight, the built-in search feature. Whenever you search for a file or open Spotlight to find apps, it is this service that quickly pulls up results based on the index it maintains. This index includes your files, emails, apps, and more. While this feature is handy, when corespotlightd malfunctions or becomes overburdened, it can result in high CPU usage, which in turn slows down your Mac.
Why does corespotlightd cause high CPU usage?
The corespotlightd process uses your CPU resources to index files on your system. While indexing is necessary for fast searches, it can be CPU-intensive, especially if you’ve recently added many new files or connected external drives. Additionally, software glitches or bugs in macOS can make the process run inefficiently.

Common Reasons for High CPU Usage
File Indexing and Spotlight
How does Spotlight work?
Spotlight is macOS’s powerful search engine, indexing all the data on your system to provide real-time search results. When you search for something, whether it’s a document, photo, or app, Spotlight quickly scans its index to retrieve the information. It’s what makes macOS search so fast and intuitive.
Why is indexing resource-intensive?
Whenever you add new files, delete data, or make significant changes to your system, corespotlightd has to update its index. This process can demand considerable CPU power, especially if large files or external drives are involved.
Software Glitches and Bugs
Sometimes, bugs in macOS or specific apps can cause corespotlightd to behave abnormally. After certain updates or changes to your system, the process may get stuck, leading to continuous high CPU usage.
Hardware Limitations
If you’re using an older Mac or one with limited hardware resources (such as low RAM or a slow hard drive), corespotlightd might struggle to complete its indexing tasks efficiently, causing CPU spikes.
How to Identify Corespotlightd High CPU Usage
Using Activity Monitor
The best way to identify if corespotlightd is causing high CPU usage is by opening Activity Monitor.
Monitoring Processes
Navigate to the “CPU” tab and sort the processes by CPU percentage. If you see corespotlightd near the top, it’s a clear indicator that this service is consuming an excessive amount of CPU resources.
Checking CPU Consumption
Take a look at how much CPU corespotlightd is using. If it’s consistently over 50%, you’ve got a problem that needs addressing.
Other Indicators of System Performance Impact
Aside from checking Activity Monitor, other signs of high CPU usage by corespotlightd include a hot MacBook, loud fans, and sluggish overall performance.

Solutions for Reducing Corespotlightd CPU Usage
Rebuilding Spotlight Index
One common fix for corespotlightd issues is rebuilding your Spotlight index.
How to rebuild the index on macOS
To rebuild the index, open System Preferences, go to Spotlight, and then the Privacy tab. Drag your hard drive into the privacy list, then remove it. This will force Spotlight to reindex your files from scratch.
When should you rebuild the index?
Rebuilding is useful if you’ve recently added a lot of files or changed storage configurations.
Excluding Specific Folders from Spotlight
Another way to reduce CPU usage is by excluding certain folders from Spotlight.
How to exclude folders from Spotlight
Under the same Spotlight settings, you can manually add specific folders to the Privacy tab to prevent them from being indexed.
Why certain folders trigger high CPU
Folders with a high volume of files, such as Downloads or Documents, can cause intensive indexing. Excluding these can free up system resources.
Updating macOS and Software
Keeping your system up-to-date is crucial for avoiding bugs and optimizing system performance.
Importance of keeping macOS updated
Apple often releases updates that include bug fixes, which can directly address issues like high CPU usage by background processes.
Bug fixes and performance improvements
If you haven’t updated in a while, installing the latest macOS version can resolve many performance problems.
Restarting or Resetting corespotlightd
Sometimes, a simple restart of the corespotlightd service can resolve temporary issues.
Steps to restart the service
You can do this by opening Terminal and typing the following command:
Copy code
sudo killall corespotlightd
This will force the process to restart, often resolving temporary glitches.
Resetting if necessary
If restarting doesn’t help, resetting your Spotlight settings might be required, which would involve rebuilding the index from scratch.
Preventing Future Corespotlightd Issues
Optimizing Spotlight Settings
Regularly reviewing and optimizing Spotlight settings can prevent issues from cropping up again. Make sure you only index folders that you frequently search.
Regular macOS Maintenance
Importance of keeping your system clean
Maintaining your macOS system with regular cleanups, removing unnecessary files, and optimizing performance settings can help avoid future performance bottlenecks.
