"Usernoted" process eating all my cpu [duplicate]
For the past couple of weeks, a process identified as usernoted
appeared to "take over" my machine after a few hours of use, eating over 99% of available CPU.
Force quitting the process doesn't help; only a system restart puts usernoted
to sleep for a while.
What is this process and how do I get it under control?
I am running OS X 10.10.5 (build 14F1021).
Solution 1:
Usernoted is a process that is responsible for notifications on OS X.
The instructions from this post solved usernoted sitting at 100% CPU on my Mac, even though they were intended to only fix stuck Notification settings:
- Open the Library folder in your Home folder.
- In the Library folder, open the Application Support folder.
- Locate the folder named NotificationCenter. Drag this folder to the desktop.
-
Next, open the Terminal application. Copy and paste each line of these commands into the Terminal window, in order. Press return after each line:
cd `getconf DARWIN_USER_DIR` rm -rf com.apple.notificationcenter killall usernoted; killall NotificationCenter
Close the Terminal app.
- Restart your computer.
For me, the problem started after I had upgraded from Yosemite to El Capitan: usernoted was constantly sitting at 100% CPU and nothing I tried (force-quitting usernoted, checking if Growl or Bark are installed, booting into safe mode, SMC reset, running all the maintenance and cleaning scripts in Onynx, etc.) seemed to help until I tried the steps listed above.
Solution 2:
I had same problem, at last, I found that it was because of Webpack
I'm using in a frontend project. Webpack is a command line tool. Many terminal-notifier
processes are consuming much CPU resources.
Once I quit Webpack, usernoted
exits, and CPU become quiet!
