Hi all. I was trying to figure out why my computer won't sleep when it's scheduled to, and I came across this item in Activity Monitor: "UserEventAgent(not responding)". It's highlighted in red, takes no CPU cycles, but lists about 800 MB in virtual memory. It's always there, regardless of restart, quitting all apps, priv reset, etc. I don't know if this is causing my problem- when I quit it in Activity Monitor, nothing seems to happen. Does anyone know what this is, and how to get rid of it? Thanks.

    Google UserEventAgent and read the many hits.

    Do you use ProTools? I've heard reports of it's audio plug-in causing issues.
    /Library/Audio/Plug ins/HAL

    UserEventAgent is used to load plug-ins for the system in response to user generated events...

    Thanks. Seems to be a multifaceted problem. I guess I can wait for a fix before I go deleting things that I just may need!

    Your choice, but I suspect it's not a common problem and you'll have to check out the various solutions, since I don't expect Apple to fix something that might not be broken.

    I just had the same problem. 'Usereventagent' wasn't responding in Activity Monitor.
    I noticed it was interfering with iTunes and other apps.

    It began after I installed 'Steermouse' a program to re-key buttons on a Bluetooth mouse.

    Using info found on a google search, I deleted the following file: BluetoothUserAgent-Plugin.plugin (System>>Library>>Usereventplugins) I also uninstalled 'Steermouse'. Problem solved.

    I'm still using my Bluetooth mouse (and headphones) without incident.
