Some time ago I turned off Spotlight all the way, since I rarely need it and it's rather annoying, since it does make the fans go crazy more often than not. But then, other times I think it's helpful and I go back to turning it on again. Until the next time when too much fan noise… and so the story goes.
Here are the commands just in case you do want to do the same:
The primary method by using
launchctl which loads/unloads the Spotlight mds agent into
This command requires your admin password.
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
To reenable Spotlight just reload it with the same command using launchctl:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
Another way is to disable/enable Spotlight is with the
mdutil command, which sets the indexing status for the provided volumes to on or off.
You"ll also need your admin password to do so.
sudo mdutil -a -i off
sudo mdutil -a -i on
