5 Ways To Fix accountsd high CPU Bug

There’s no general fix for this problem. Until Apple acknowledges the glitch and issues a software update with a fix you can apply these temporary troubleshooting tips:

1. Sign Out Of Apple ID

Some users have confirmed that the accountsd bug is fixed if you sign out of your Apple ID and restart your Mac. However, it resurfaces if you sign back in with your Apple ID. If you’re ready to severe the ties of your Mac with your iCloud until an official fix is provided, proceed as follows:

  • 1. Open System Preferences from your Dock, or by clicking the Apple logo in the top-left corner of the screen.
  • 2. Click on Apple ID, available in the right area of the System Preferences header.
  • 3. Click Overview, the first item in the left sidebar.
  • 4. Use the Sign Out… button.
  • 5. Reboot your Mac, by clicking on the Apple logo in the top-left corner and Restart…

2. Reset SMC

The System Management Controller makes sure that some basic functions of your Mac still work even when the computer is turned off. Some examples are the ability to respond to presses of the power button, battery management, thermal management, ambient light sensing and much more.

To reset the SMC means that you have to cut the power completely from your Mac. With older Mac models (older than 2009) the SMC is reset by turning off the computer, removing the battery and pressing & holding the power button for 5 seconds, before reconnecting back the battery and turning the device back ON.
For newer Macs please follow these steps:

  • 3. Keep all four buttons pressed for 10 seconds, before letting go.
  • 4. Reconnect your Mac to a power source and turn it back ON.
