Mac Spotlight Not Working? How to Fix Search

💡 Quick answer: The most common fix for Mac Spotlight not working is rebuilding the search index: go to System Settings, Siri & Spotlight, Spotlight Privacy, add your Macintosh HD drive to the exclusion list, then remove it — Spotlight rebuilds the index over the next 15-60 minutes. The faster Terminal method is sudo mdutil -E / to erase and rebuild the index. If Spotlight won't open at all, first confirm the Command+Space shortcut is enabled under System Settings, Keyboard, Keyboard Shortcuts, Spotlight, and make sure the drive has at least 10-15GB free.

Spotlight not opening, showing no results, or can't find apps and files? Here's how to fix Spotlight search on any Mac running macOS.

Fixes to Try

1 Check Spotlight Keyboard Shortcut

The shortcut may have been changed or disabled:

  1. Go to System Settings → Keyboard → Keyboard Shortcuts
  2. Click Spotlight in the left panel
  3. Make sure "Show Spotlight search" is enabled
  4. The shortcut should be Command + Space
  5. If it's set to something else, click it and press Command + Space to reset

2 Rebuild the Spotlight Index

This is the most common fix — forces Spotlight to re-index everything:

  1. Go to System Settings → Siri & Spotlight → Spotlight Privacy
  2. Click the + button and add your main drive (usually "Macintosh HD")
  3. Click Done
  4. Wait a few seconds, then go back to Privacy
  5. Select the drive you just added and click − to remove it
  6. Click Done
  7. Spotlight will now rebuild its index — this can take 15-60 minutes
Patience required: During re-indexing, Spotlight results will be incomplete. Let your Mac sit for an hour before testing again.

3 Re-index via Terminal (Faster)

Force a complete re-index using command line:

  1. Open Terminal
  2. Run: sudo mdutil -E /
  3. Enter your password
  4. This erases and rebuilds the entire index
  5. Also run: sudo mdutil -a -i on to make sure indexing is enabled

4 Check What Spotlight Is Allowed to Search

Some categories may be disabled:

  1. Go to System Settings → Siri & Spotlight
  2. Scroll down to Search Results
  3. Make sure the categories you need are checked (Applications, Documents, etc.)

5 Restart the Spotlight Service

  1. Open Terminal
  2. Run: sudo killall mds
  3. Spotlight's indexing daemon will restart automatically
  4. Wait a minute, then test Spotlight

6 Restart Your Mac

Sometimes the mds process just needs a clean restart:

  1. Go to Apple menu → Restart
  2. After restart, wait a few minutes before testing Spotlight

7 Check Available Disk Space

Spotlight can't index if the drive is nearly full:

  1. Go to Apple menu → About This Mac → Storage
  2. Make sure you have at least 10-15GB free
  3. If low, free up space and then re-index

8 Update macOS

  1. Go to System Settings → General → Software Update
  2. Install any available updates
  3. Restart and test Spotlight

Still Not Working?

If Spotlight still doesn't work after re-indexing, there may be a deeper macOS corruption issue that requires professional diagnosis or a reinstall.

❓ Frequently Asked Questions

Why is Spotlight not showing any results on my Mac?

A corrupted search index is the usual cause. Rebuild it via System Settings, Siri & Spotlight, Spotlight Privacy — add your main drive, then remove it — or run sudo mdutil -E / in Terminal for a full erase-and-rebuild. Expect incomplete results for 15-60 minutes while re-indexing runs.

How do I rebuild the Spotlight index from Terminal?

Open Terminal and run sudo mdutil -E /, which erases and rebuilds the entire index, then run sudo mdutil -a -i on to confirm indexing is enabled. You can also restart the indexing daemon with sudo killall mds — it relaunches automatically within a minute.

Why won't Command Space open Spotlight?

The keyboard shortcut may have been changed or disabled. Go to System Settings, Keyboard, Keyboard Shortcuts, click Spotlight, and make sure Show Spotlight search is enabled and set to Command+Space; if it's mapped to something else, click it and press Command+Space to reset.

Why can't Spotlight find apps I have installed?

Check that the Applications category is enabled under System Settings, Siri & Spotlight, Search Results, and verify the drive isn't nearly full — Spotlight can't index without roughly 10-15GB of free space. If categories are enabled and space is fine, rebuild the index; if it still fails after re-indexing, deeper macOS corruption may require an update, professional diagnosis, or a reinstall.
