    It is a critical system process that launches and manages other system process and functions. It usually one of the first process that is started upon startup and it in turn starts up other processes. Do not remove, kill, or alter it in any way.

    launchd is the first process that runs after your computer finishes its boot cycle. It's responsible for running the critical system processes at the right time, including scheduled jobs and maintenance tasks.

    Look at me getting in on this A YEAR AFTER THE FACT!
    Anyway. Do 'launchd' processes run for a while or are they supposed to stop after a bit? I've had 'launchd' running about 90% of my CPU at times.

    Some may run for a short time and some may run all the time your computer is up. If you're having a problem, check what you have set to automatically launch at startup. Check the following locations:
    • System Preferences > Accounts > yourusername > Login Items
      (Lion and ML users: System Preferences > Users & Groups > yourusername > Login Items)

    • /Library/LaunchAgents/
      (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)

    • ~/Library/LaunchAgents/
      (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)

    • /Library/StartupItems/
      (Lion and ML users: In Finder, click Go > Go to Folder > then enter the path above)
    To see what's currently using system resources:
    1. Launch Activity Monitor
    2. Change "My Processes" at the top to "All Processes"
    3. Click on the CPU column heading once or twice, so the arrow points downward (highest values on top).
    4. Click on the System Memory tab at the bottom.
    5. Take a screen shot of the entire Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
    6. Post your screenshots.

    Sorry, not to threadjack, but do you (of course you do) know anything about helpd? It crashes all the time on my late 2011 MBP (pretty much since purchase in Jan). It doesn't seem to do anything when it goes down and I'm not terribly worried about it, it just seems to happen all the time.

    I haven't reviewed all of this, but it may help: Troubleshooting Help Viewer

    Thanks, had read some stuff about clearing out the cache but didn't seem to do anything, I'll look into it some more.
