If you are like me then you probably had the issue where your SpotLight would just always index/re-index and slow your system down.
If you are annoyed like I was here are instructions on how to disable and re-enable SpotLight indexing on Mac OS X Yosemite, Mavericks, Mountain Lion, and Lion. (I am doing this on LION 10.7.4):
DISABLE SPOTLIGHT
If you ever want to re-enable SpotLight again then follow the instruction below:
1) Launch the Terminal go to Finder>Applications>Utilities folder and double click “Terminal” application to lunch it.
2) Input the following command into the Terminal window and press Return/Enter. (without quotes)
“sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist”
3) Enter your administrative password if/when prompted.
4) DONE: SpotLight has been disabled and no longer functions as it did before
ENABLE SPOTLIGHT
If you ever want to re-enable SpotLight again then follow the instruction below:
1) Launch the Terminal go to Finder>Applications>Utilities folder and double click “Terminal” application to lunch it.
2) Input the following command into the Terminal window and press Return/Enter. (without quotes)
“sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist”
3) Enter your administrative password if/when prompted.
4) DONE: SpotLight has been enabled and will start to index again/function as it did before with all it’s features.
