macOS Spotlight Not Working — Search Not Finding Files Fix

What Does This Error Mean?

When Spotlight stops finding files or apps, it usually means the search index has become corrupted or a new drive is still being indexed. Spotlight works by keeping a constantly updated index of every file on your Mac. When this index is broken, Spotlight cannot find things even though the files are still there.

Common Causes

The Spotlight index has become corrupted and needs to be rebuilt
Spotlight is still indexing a drive that was recently added or your Mac after a fresh macOS install
The folder containing the files is excluded from Spotlight in Privacy settings
A recent macOS update interrupted the indexing process
Low disk space is preventing Spotlight from maintaining its index

How to Fix It

Check if Spotlight is still indexing. Click the Spotlight icon in the menu bar (magnifying glass). If a spinning progress bar appears below the search field with 'Indexing,' Spotlight is actively working — wait for it to finish.

On a Mac with a large drive and many files, the initial indexing process can take several hours.
Check that the folder is not excluded. Go to System Settings > Siri and Spotlight > Spotlight Privacy. Look for your drive or any folder in the exclusion list. If you see them, select and remove them.

Items in the Privacy list are completely hidden from Spotlight. Removing them from the list makes them searchable again.
Rebuild the Spotlight index. Go to System Settings > Siri and Spotlight > Spotlight Privacy. Drag your main drive (Macintosh HD) from the Finder Desktop into the Privacy list. Wait 10 seconds. Then remove it from the list. This forces a full index rebuild.

Adding your drive to the exclusion list tells Spotlight to stop indexing it. Removing it tells Spotlight to start over from scratch.
Rebuild using Terminal. Open Terminal (Applications > Utilities) and type: sudo mdutil -E / then press Enter. Enter your password when prompted.

The mdutil command directly controls the Spotlight indexing service. The -E flag erases and rebuilds the index. The / means your main drive.
Free up disk space if needed. Go to Apple menu > About This Mac > More Info > Storage. If your drive is nearly full, Spotlight cannot write its index files. Free up at least 10% of your drive capacity.

The Spotlight index itself can be several GB on a well-used Mac. Without free space, Spotlight cannot build or update its index.

When to Call a Professional

You should never need professional help for Spotlight not working. This is entirely a software issue that is fixed by rebuilding the index. If Spotlight takes more than 24 hours to rebuild after following these steps, check that your drive has enough free space.

Frequently Asked Questions

How long does it take to rebuild the Spotlight index?

On an SSD with a typical amount of data, rebuilding takes 1 to 3 hours. On an older Mac with a spinning hard drive and lots of files, it can take 6 to 12 hours. Your Mac remains usable during indexing, but it may be slower than usual.

Can I use my Mac while Spotlight is rebuilding?

Yes — you can use your Mac normally while Spotlight rebuilds in the background. You may notice the Mac is slightly slower, especially on older hardware. Spotlight search results will be incomplete until indexing is finished.

Spotlight finds apps but not documents. What does that mean?

This usually means your Documents folder (or wherever you store files) has been added to Spotlight's Privacy exclusion list. Check System Settings > Siri and Spotlight > Spotlight Privacy and remove any folder that should be searchable.
