Fix Mac Hot Corners Not Working on macOS Sonoma, Ventura, or Monterey

Unfreeze Hot Corners, restore them now!

While macOS is already a highly capable operating system, the Hot Corners feature takes it a step further. It allows users to set specific quick actions for each of these four corners on the screen, which can be triggered by moving the cursor to any of these. However, users have complained that after the recent update or when they remove an external monitor, Hot Corners does not seem to be working on their Mac PC.

Why is Mac Hot Corners Not Working and How to Fix It?

The reasons why the issue occurred could be a problematic external monitor and its incorrect configuration, and interference from Bluetooth devices, or third-party software.

Quick Answer

Make sure to update your Macbook and then restart it. If this does not help, quit the dock from the Activity Monitor.

Method 1: Change Hot Corners actions

You can try changing the present actions of your hot corners to see if some specific action isn’t working or if your hot corners in general have an issue. Follow the steps mentioned below under the section How to Enable or Disable Hot Corners on MacOS Sonoma/Ventura/Monterey to do the same.

Method 2: Alter Modifier Keys

If Mac Hot Corners continue to fail, check whether that corner’s action has an additional key selected. It’s likely that while creating the action, you must have hit one of the modifier keys, such as Shift, Option, Command, or Control. In that case, the hot corner will only work if you are holding the key whilst moving the cursor. 

1. Click on the Apple logo at the top-left corner of the screen and select System Preferences from the menu.

2. Move to the Desktop & Dock tab and click on Hot Corners in the right pane.

Note: The name can be Desktop & Screen Saver under other MacOS devices.

3. Now check if there is a modifier key icon next to any action. If there is one, you can change it back or perform the action while holding the keys.
