How can I quit frozen Spotlight without rebooting my computer?

I opened up Spotlight, typed '12*' to do some multiplication and it's been frozen for the last 20 minutes.

I am looking for how to restart the program/service/whatever it technically is, but it's not in the Force Quit menu, so what is the quickest way to kill this process without restarting my computer? (I am on Mac OS X Snow Leopard)


Depending on your OS and luck, it could actually be 1 of at least a few [services]:

  • mds
  • SystemUIServer
  • Spotlight

To me, a while back when they were called feline names, I've had the same issue (as I was saying on the comments) and it was not Spotlight: it was the Menubar. Just like with spotlight, we simply have to kill it so it will be restarted by launchd.

For that, use the Activity Monitor and search for your [service].

Or you may instead use the Terminal, for instance:

killall Spotlight

And if that doesn't work, consider using sudo.


Just ran into Spotlight itself crashing. The answer for that problem is just going to the Terminal and typing:

killall Spotlight

Fixed the Spotlight freeze problem!


The first post is correct that mds is the process for spotlight. You can kill it in activity monitor or:

sudo killall mds

from the terminal. The process will restart automatically as it is managed as a launchd item that is set to always be running.

You might look at

man mdutil

as well. This is a utility at the command line for managing mds settings on volumes.


It'll probably show up in /Applications/Utilities/Activity Monitor.app. Select All Processes in the toolbar to see processes of all users.


The screenshot is from when I was searching something. I guess you'd kill mds by pressing Cmd-Opt-Q after selecting it to terminate Spotlight, but I'm not sure -- probably best if you checked CPU usage and/or if the name of a process is written in red, indicating it froze.
