Spotlightknowledged macOS High CPU

What is spotlightknowledged on Mac?

Spotlightknowledged is a background process in macOS that works alongside Spotlight and Siri to improve how your Mac gathers and displays contextual search results. From our experts’ observations, it’s part of the Core Spotlight framework that analyzes and indexes data such as documents, messages, photos, and app metadata to make searches faster and more relevant.

 

When something goes wrong, like a corrupted index or continuous re-indexing, it can lead to spotlightknowledged macOS high CPU usage, which slows down your device and drains battery life.

 

You can test your Mac performance to locate the process in Activity Monitor by opening Applications > Utilities > Activity Monitor, then searching for spotlightknowledged in the CPU tab. If it’s consistently using more than 50–60% of your processor for extended periods, your Mac may need optimization or a cleanup to restore balance.

Why spotlightknowledged causes high CPU usage?

Spotlightknowledged may cause macOS to show MacBook Spotlight using significant energy when it scans or reindexes files. The process reads large volumes of metadata to update Spotlight’s search database, which can temporarily raise CPU load. This usually happens after system updates, disk changes, or when indexing external drives.

A note from our experts: 

 

From our experience, when spotlightknowledged causes high CPU load or your MacBook shows the MacBook Spotlight using significant energy warning, redundant background processes are often the reason.

 

Instead of quitting them manually, which can risk interrupting essential system tasks, our team suggests using MacKeeper, developed by Clario Tech, which offers the Memory Cleaner feature. It safely identifies memory-draining services like spotlightknowledged and clears them without affecting your system stability.

 

Here’s how to do it:

  1. Download MacKeeper from our official website and install it on your Mac.
  2. Open the app and choose Memory Cleaner from the left sidebar.
  3. Click Open to review current memory usage and see which processes consume the most RAM.
  4. Select Clean Memory to close unneeded background services and free up resources instantly.
  5. Keep MacKeeper running in the background to automatically maintain optimal memory balance.
Open MacKeeper and select Memory Cleaner from the left-side menu bar to view active processes and manage your Mac's memory usage efficiently.
Step 1. Choose Memory Cleaner from the left-side menu bar
Click Open in Memory Cleaner to display detailed memory consumption data and identify which apps or processes are using the most RAM on your Mac.
Step 2. Click Open to see memory consumption information
Press the Clean Memory button in MacKeeper to release unused RAM, close background processes, and instantly free up disk space for smoother performance.
Step 3. Hit the Clean Memory button to free up disk space

How to fix spotlightknowledged high CPU usage on Mac?

You can fix spotlightknowledged macOS high CPU usage by checking which processes are overloading the system, rebuilding the Spotlight index, and clearing unnecessary background tasks. From our tests, these steps help stabilize CPU performance, reduce fan noise, and prevent overheating without affecting normal search functionality.

1. Check system activity and confirm the CPU spike

When your Mac slows down or fans get loud, you need to check how to see how much CPU is being used on the Mac to verify that spotlightknowledged is responsible.

 

Try the following:

  1. Open Activity Monitor from Applications > Utilities.
  2. Click the CPU tab to display live processor usage.
  3. Sort by % CPU and locate spotlightknowledged at the top.
  4. If it constantly exceeds 60% for several minutes, close unnecessary apps and keep your Mac plugged in while Spotlight completes indexing.
Open Activity Monitor from Applications > Utilities to check active processes, monitor CPU usage, and identify tasks causing high load on your Mac.
Step 1. Open Activity Monitor from Applications > Utilities
Click the CPU tab in Activity Monitor to view real-time processor usage and identify processes consuming excessive CPU resources on your Mac.
Step 2. Click the CPU tab to display live processor usage
Sort the list by % CPU in Activity Monitor to quickly identify which apps or background processes are using the most processing power on your Mac.
Step 3. Sort by % CPU
Locate spotlightknowledged at the top of the Activity Monitor list to confirm it’s the process currently consuming the highest amount of CPU resources.
Step 4. Locate spotlightknowledged at the top

2. Rebuild the Spotlight index to stop mds_stores Mac high memory issues

If both spotlightknowledged and mds_stores Mac high memory occur, the Spotlight index may be corrupted. Rebuilding it forces macOS to start fresh and resolve continuous CPU load.

 

Here’s how:

  1. Open Terminal from Applications > Utilities.
  2. Type sudo mdutil -E / and press Return.
  3. Enter your admin password to confirm the command.
  4. Keep your Mac plugged in while Spotlight rebuilds its database.
Open Terminal from Applications > Utilities to run system commands that help rebuild Spotlight’s index and reduce high CPU or memory usage on your Mac.
Step 1. Open Terminal from Applications > Utilities
Type sudo mdutil -E / in Terminal and press Return to force macOS to erase and rebuild the Spotlight index, resolving ongoing CPU or memory issues.
Step 2. Type sudo mdutil -E / and press Return

3. Review startup and background items to reduce hidden load

After rebuilding, it’s important to learn how to see what is running on your Mac and stop redundant background tasks that restart automatically.

 

Follow these steps:

  1. Open System Settings, then go to General > Login Items & Extensions.
  2. Remove unnecessary apps that start every time you log in.
  3. Revisit Activity Monitor to confirm reduced CPU activity.
  4. Run MacKeeper’s Memory Cleaner to close leftover system processes safely and keep CPU usage balanced.
Open System Settings, navigate to General > Login Items & Extensions, and remove unnecessary startup apps to reduce background load and improve Mac performance.
Step 1. Open System Settings, then go to General > Login Items & Extensions and remove unwanted apps
Press the Clean Memory button in MacKeeper to release unused RAM, close background processes, and instantly free up disk space for smoother performance.
Step 2. Run MacKeeper’s Memory Cleaner to close leftover system processes

Conclusion

Spotlightknowledged macOS typically uses more CPU when indexing files, rebuilding search data, or scanning new drives. Occasional spikes are normal, but a persistent load means it’s time to optimize your system and clear redundant background processes.

 

With Memory Cleaner, MacKeeper offers performance monitoring that helps you track demanding processes like spotlightknowledged, stabilize CPU usage, and maintain smooth macOS performance without affecting system search.
