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.
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.
