Why Is Spotlight Search Not Working After the macOS Tahoe Update?

You press Cmd+Space, type the name of an app or a file you know exists, and Spotlight comes back empty. This started after you installed macOS Tahoe, and it's not a one-time glitch. Search that used to find everything instantly now misses apps, skips your Documents folder, or stops showing Mail results altogether.

Why Did macOS Tahoe Break Spotlight Search?

macOS Tahoe reorganized how Spotlight categorizes results and changed the default settings for what gets indexed. On many Macs, the update either turned off result categories you rely on, carried over a corrupted index from the previous macOS version, or froze the background indexing process partway through.

The three most common causes, in order of how often they turn out to be the actual fix:

• A result category (Applications, Documents, Mail & Messages) got disabled during the upgrade and needs to be turned back on manually
• A folder or your whole startup disk ended up on the Search Privacy exclusion list without you adding it there
• The index itself is stale or partially corrupted from the update process and needs a rebuild

None of these mean anything is wrong with your files. Spotlight's database just needs to be checked and, in most cases, rebuilt.

How Do I Check Which Spotlight Categories Are Turned On?

Open System Settings, click Spotlight in the sidebar, and look at the list under "Search results." If Applications, Documents, or any category you expect is unchecked, that's why those results are missing.

1. Open System Settings
2. Click Spotlight in the sidebar
3. Scroll through the "Search results" list and check every category you want included: Applications, Documents, Folders, Mail & Messages, System Preferences, and the rest
4. In Tahoe, also check the newer entries near the bottom: Clipboard Search, Related Content, and Search History

Apple added several new toggles in this version, and a system update sometimes resets one or two of them to off. Turn on anything you use, then try your search again.

Is a Folder on the Search Privacy Exclusion List?

Yes, this happens more often than people expect, and it's easy to miss because the excluded item doesn't show up anywhere obvious until you check this specific list.

1. Open System Settings, click Spotlight
2. Click Search Privacy near the bottom of the pane
3. Look through the list for your home folder, Documents, Desktop, or your entire startup disk
4. Select any folder that shouldn't be there and click the minus button to remove it

If your whole disk appears in this list, Spotlight will not index anything on it, which explains why search feels completely broken instead of just missing a few results. Removing it here triggers a fresh index of everything that was excluded.

How Do I Rebuild the Spotlight Index on macOS Tahoe?

Use the mdutil command in Terminal to force a full reindex. This clears out whatever got corrupted during the update and rebuilds the search database from scratch.

Open Terminal (Applications, Utilities, Terminal) and run:

sudo mdutil -E /

Enter your admin password when prompted. This erases the existing index on your startup disk and tells macOS to build a new one immediately. You'll see a message confirming indexing has started.

Check that indexing is actually enabled first if the erase command doesn't seem to do anything:

sudo mdutil -i on /

This turns indexing back on for your startup disk in case it got switched off, then run the -E command again to force the rebuild.

To check how the reindex is progressing:

mdutil -s /

This reports whether indexing is in progress or complete. While it runs, Spotlight results will be incomplete, and you may notice mdworker and mds processes using more CPU than normal in Activity Monitor. That's expected. Leave your Mac plugged in and awake until it finishes.

Why Are Only Some Apps Missing From Spotlight?

This usually means the affected apps live outside the standard Applications folder, or their metadata got skipped during a partial index. Apps installed through a package manager, moved manually, or living in a subfolder are the most common cases.

Check where the missing app actually is. If it's not in /Applications or ~/Applications, Spotlight may deprioritize it even after indexing finishes. Move it into /Applications if possible, then run:

sudo mdimport /Applications/AppName.app

Replace AppName.app with the actual file name. This forces Spotlight to import metadata for that one item without waiting for a full disk reindex, and it's the fastest way to fix a single missing app instead of rebuilding your entire index.

Should I Restart Before Trying Anything Else?

Yes, but only after you've made the changes above. A restart on its own does not fix disabled categories or excluded folders. It matters because Tahoe sometimes needs a fresh boot for the mds indexing service to pick up settings changes cleanly.

Make your changes to Search Privacy and categories first, run the mdutil -E command, then restart your Mac once. Restarting before making changes just gives you the same broken state back.

What if Spotlight Still Doesn't Work After a Full Reindex?

Check for a macOS point update before troubleshooting further. Apple has shipped several updates since the initial Tahoe 26 release, including 26.6.1 in early August 2026, and indexing bugs are a common target for these smaller patches.

1. Open System Settings, click General, then Software Update
2. Install any update listed
3. Restart, then run sudo mdutil -E / one more time after the update completes

If Spotlight is still broken after a point update and a full reindex, check Console.app for mds or mdworker crash logs. Open Console, search for "mds" in the search field, and look for repeated crash or error entries around the times you tried to search. A recurring crash there points to a corrupted file in your index that a plain reindex isn't clearing, and that's a case worth reporting to Apple through Feedback Assistant with the specific log lines attached.

Could Third-Party Search Tools Be Conflicting With Spotlight?

Yes, if you run Alfred, Raycast, or a similar launcher alongside Spotlight, check whether it changed the Cmd+Space shortcut or its own indexing settings during the Tahoe update.

These apps often take over the Cmd+Space shortcut, so when Spotlight itself "isn't working," you may actually be looking at Alfred's or Raycast's own search window, which has a separate index with its own settings. Open the third-party app's preferences and check its hotkey assignment against System Settings, Keyboard, Keyboard Shortcuts, Spotlight. If both are set to Cmd+Space, one of them is silently losing the conflict, and results look broken because you're testing the wrong search window. Assign a different shortcut to one of them to confirm which app you're actually seeing when you search.

Quick Checklist

• Turn on missing categories in System Settings, Spotlight
• Remove any folders or your whole disk from the Search Privacy exclusion list
• Run sudo mdutil -E / to force a full reindex
• Confirm indexing is on with sudo mdutil -i on / if the reindex doesn't start
• Use mdimport on a single app if only one item is missing
• Install the latest macOS Tahoe point update if the problem persists
• Check Console.app for mds crash logs as a last step

Most people fix this with the categories check and one reindex. Give the reindex time to finish before assuming it didn't work, since search stays incomplete until it does.
