If you’re a Mac user, you may have noticed something called corespotlightd using a lot of CPU power, causing your Mac to slow down.
Corespotlightd High CPU usage can slow down your Mac by consuming excessive CPU power, often reaching 99-100%. This typically happens during Spotlight indexing. Fix it by reindexing, restarting, or updating macOS to restore performance.
In this guide, we’ll walk you through what corespotlightd is, why it consumes so much CPU, and how to fix and prevent this issue from keeping your Mac running smoothly.
What is Corespotlightd?
Corespotlightd is a background process on Mac that helps Spotlight search for files quickly. It keeps an index of all your files, so Spotlight can find it quickly when you search for something. Sometimes, it may use too much CPU, slowing down your computer.
What is Process Corespotlightd?
The process corespotlightd manages the indexing of your Mac’s files and apps. This helps Spotlight search results appear quickly.
Corespotlightd updates the index to keep it accurate whenever files are added or changed. Sometimes, this can cause high CPU usage, making your system feel slower.
Why Does Corespotlightd Cause High CPU Usage?
Corespotlightd can use a high CPU when it’s indexing a lot of files or updating frequently. This happens when new files are added, external drives are connected, or system glitches occur. The process works harder, causing your Mac to slow down.
1. Scenarios:
Corespotlightd often causes high CPU usage in specific situations. For example, adding or removing many files, connecting external drives, or updating apps.
It can also happen if the Spotlight index is broken or corrupted, forcing corespotlightd to use more resources to rebuild the index.
How To Diagnose Corespotlightd CPU Issues:
1. Monitoring With Activity Monitor:
Activity Monitor helps you track how much CPU each process uses. Open it from your Mac’s Utilities folder. If corespotlightd uses too much CPU, you’ll see it at the top of the list, indicating a problem.
2. Identifying Abnormal Usage:
Abnormal usage happens when corespotlightd uses too much CPU even if you’re not doing much. If your Mac feels slow, the fans are loud, or it gets hot without heavy tasks, check Activity Monitor for high usage.
Solutions To Reduce Corespotlightd High CPU Usage:
1. Optimizing Spotlight Indexing:
You can optimize Spotlight indexing by excluding unnecessary folders or drives from being indexed. This reduces the amount of data corespotlightd needs to process, helping your Mac run faster and use less CPU.
2. Clearing And Rebuilding Indexes:
If Spotlight’s index is corrupted, corespotlightd may overwork. To fix this, go to System Settings > Spotlight, add your drive to the “Privacy” list, wait a few minutes, and remove it to rebuild the index.
3. Managing Large Files And External Drives:
To reduce corespotlightd CPU usage, disconnect external drives when not in use and delete unnecessary large files. This prevents Spotlight from indexing too much data, lowering your Mac’s CPU strain.
Preventing Future Corespotlightd CPU Spikes:
1. Regular System Maintenance:
Keep your Mac running smoothly by performing regular maintenance. Clean up unnecessary files, repair disk permissions, and clear caches. These steps ease the workload on corespotlightd, preventing high CPU usage in the future.
