When Spotlight stops working on a MacBook — the search bar returns nothing, shows the wrong results, or the spinning progress bar never finishes — it is almost always the search index that has broken, not your files. macOS keeps a hidden index of everything on your drive; when that index gets corrupted (often after a macOS update, a big file copy, or an unexpected shutdown), Spotlight comes up empty. The fix is to make macOS rebuild that index. Work through these steps in order and search will come back.
First: is it actually broken, or still indexing?
Press Command-Space and start typing. If you see a small progress bar under the search field that says "Indexing," Spotlight is not broken — it is rebuilding and will finish on its own. This happens normally after a macOS update or restart. Leave the Mac plugged in and awake for 30 to 60 minutes (large drives can take longer) and try again. If there is no progress bar and results are still empty or wrong, move on.
Fix 1: Restart your Mac
The simplest fix works more often than you would expect. A restart clears the indexing daemon (mds) and lets it start clean. Choose Apple menu › Restart — do not just close the lid. After it boots, give it a few minutes, then test Spotlight again before trying anything more involved.
Fix 2: Check your keyboard shortcut and scope
Sometimes Spotlight is fine but the shortcut got disabled or the categories got unchecked. Open System Settings › Keyboard › Keyboard Shortcuts › Spotlight and confirm "Show Spotlight search" is enabled (default is Command-Space). Then open System Settings › Spotlight and make sure the categories you want (Applications, Documents, Folders, etc.) are checked. If everything you search for is one category that happens to be unchecked, it will look "broken" when it is just filtered out.
Fix 3: Force a rebuild with the Privacy trick (no Terminal)
This is the reliable no-command-line way to make macOS throw away the corrupted index and build a fresh one:
- Open System Settings › Spotlight, then scroll down and click Search Privacy… (on older macOS: System Preferences › Spotlight › Privacy).
- Click the + button and add your Macintosh HD (your whole startup drive) to the "prevent Spotlight from searching" list. Confirm when it warns you.
- Wait about 30 seconds. This tells macOS to stop indexing that drive and discard its index.
- Select Macintosh HD in that list and click the – button to remove it.
- As soon as you remove it, macOS starts indexing the drive from scratch. You will see the "Indexing" bar in Spotlight. Let it finish (plug in, keep the Mac awake). Search will work once it completes.
Fix 4: Rebuild the Spotlight index from Terminal (mdutil)
If the Privacy trick did not stick, force the rebuild directly. Open Terminal (Applications › Utilities › Terminal, or search for it in Launchpad) and run this command, then enter your login password when prompted (the password will not show as you type — that is normal):
sudo mdutil -E /
The -E flag erases the existing index for your startup volume and rebuilds it. If it reports that indexing is disabled, turn it back on first with:
sudo mdutil -i on /
Then re-run the erase command. You can watch overall status any time with mdutil -s / (it will say "Indexing enabled"). Give the rebuild time to complete before judging whether it worked.
Fix 5: Delete the index files (last resort)
If mdutil will not rebuild, you can remove the index store and force macOS to regenerate it. In Terminal:
sudo rm -rf /.Spotlight-V100
Then restart. macOS recreates .Spotlight-V100 and reindexes on the next boot. Only do this if the earlier steps failed — and make sure you have a current backup first, which you should have anyway.
Still no search? A few deeper causes
- Low free space. Indexing needs room to work. If your drive is nearly full, Spotlight can stall. Free up space and try Fix 4 again — our guide to a MacBook that is running slow covers clearing storage.
- Permissions or a corrupt user account. Try creating a new test user (System Settings › Users & Groups) and see if Spotlight works there. If it does, the issue is your account, not macOS.
- Failing drive. On very old Intel MacBooks with a spinning or aging SSD, repeated index corruption can signal hardware trouble. Run First Aid in Disk Utility. If the drive is failing, indexing will keep breaking no matter how many times you rebuild.
- You just want it faster and more private. If search works but feels sluggish or you do not want web results, our full guide to using Spotlight on Mac shows how to trim categories and turn off Siri Suggestions.
When it is not worth the fight
If Spotlight keeps corrupting, the Mac is slow across the board, and it is an older Intel model, the underlying hardware may be on its way out. Sometimes the smarter move is a clean, tested machine that just works. A refurbished Apple Silicon MacBook Air (M1) starts at just $450 at LuxuriousComputers — indexed instantly, fast search, and years of macOS updates ahead of it. Browse the current Apple clearance deals, and if your old Mac still has value, we will take it in on trade-in — even if the search never works again.
The bottom line
Spotlight not working almost always means a broken search index, and macOS is happy to rebuild it. Start with a restart, then the Privacy-pane trick, then sudo mdutil -E / from Terminal. Give each rebuild time to finish. If search keeps breaking on an old Mac, that is your sign the machine — not just the index — is ready for an upgrade.
