Does your Mac fail to find files that you know exist when you search for them? Or, does Apple Mail or Outlook fail to find email messages when you search for them? If so, this problem could be caused by a corrupt Spotlight index. Spotlight is the name of Apple’s search capabilities built into the Mac operating system. Spotlight’s index can get damaged from time to time.
When this occurs, follow the instructions below to delete and then recreate or rebuild Spotlight’s index.
- Click on the Apple menu and select System Preferences
- When the System Preferences window opens, click the Spotlight icon
- Click the Privacy tab.
- Click the Add (+) button and select your Mac’s hard drive. Typically, this named Macintosh HD. (This process triggers the Mac operating system to delete the existing Spotlight index.
- This next step may seem counter-intuitive, but click on the Mac’s hard drive that you just added then click the Remove (–) button to remove it from the list.
- Click the red dot to close this window
Spotlight will now start to reindex your Mac. Depending upon the amount of stuff you have on your Mac’s hard drive and the speed of your Mac’s processor this reindexing process could take anywhere from 30 minutes to many, many hours.
