Why Does CoreSpotlightd Use High CPU?

While it’s normal for CoreSpotlightd to occasionally use a bit of CPU when it’s actively indexing your files, there are times when this process can start consuming a much higher percentage of CPU than it should. When this happens, it can significantly affect your Mac’s performance, making everything from opening applications to browsing the web sluggish.

What Are the Common Causes of CoreSpotlightd High CPU Usage?

Several reasons could cause CoreSpotlightd to use too much CPU, including:

1. Continuous Re-Indexing: Spotlight repeatedly re-indexing your entire system can heavily load CoreSpotlightd.
2. Corrupted Spotlight Databases: A corrupt database may cause CoreSpotlightd to get stuck, endlessly processing the same data.
3. Third-Party Apps Interference: Some third-party applications may generate new data or logs continuously, leading to ongoing indexing by CoreSpotlightd.
4. Large Volume of New Files: Adding a lot of new files, such as after downloads or updates, can make CoreSpotlightd work overtime to index everything.

How Does Spotlight Indexing Work?

Spotlight is Apple’s powerful search feature found in macOS, iOS, iPadOS, and visionOS. It works by creating an index of all files and data on your device, allowing you to quickly find what you need.  

The Indexing Process:

1. Initial Indexing: When you first set up your device or after a major system update, Spotlight will scan your entire device, creating an index of all files, documents, applications, and metadata.  
2. Continuous Updates: As you add, delete, or modify files, Spotlight continuously updates the index in the background. This guarantees that the search results you see are current at all times. 
3. Metadata Extraction: Spotlight extracts metadata from files, such as:
   • File name: The name of the file.
   • Content: The text within the file.
   • File type: The type of file (e.g., document, image, audio).  
   • Date modified: The most recent modification to the file. 
   • Location: Where the file is stored.
4. Indexing Locations: Spotlight typically indexes your entire device, including internal storage, external drives, and network shares. However, you can exclude specific locations from indexing for privacy or performance reasons.  
5. Search Queries: When you enter a search query, Spotlight compares it to the indexed metadata. It returns results that match the query, ranking them based on relevance.
