Resolved: "CursorUIViewService" Not Responding and Performance Issues with Microsoft Excel on Mac

nabling Caps Lock while working in Microsoft Excel on a Mac can cause performance lags, and you may notice the "CursorUIViewService" becoming unresponsive.


Solution 1: Permanently disable Caps Lock by following these steps:

  • Go to System SettingsKeyboard ShortcutsModifier Keys.
  • Set Caps Lock Key to No Action.


Solution 2: Disable the Caps Lock indicator by running the following command in the Terminal:

sudo defaults write /Library/Preferences/FeatureFlags/Domain/UIKit.plist redesigned_text_cursor -dict-add Enabled -bool NO

(Note: This setting may reset after macOS updates.)

This worked for me. Thank you!

Hi,

I’ve spent quite some time trying to pinpoint what’s causing it to stop responding, and I’ve tried various solutions. Most recently, I’ve begun to suspect Microsoft apps or TextEdit, though I’m still not entirely sure. Could you please explain how Excel might be responsible, if you’re certain it is?

Thanks.
