How Do I Permanently Disable Hot Corners on Mac? I have a work computer, and every time I turn it on and log in, hot corners are enabled where when I move my mouse to a corner inadvertently, it locks my screen. This happens all the time in the middle of my work.

Every time, this annoys me, and I go into System Preferences and set all the hot corners options to none. But, the next day or whenever I restart my computer, they come back! I am wondering if anyone knows how to permanently disable them so I don't need to manually disable them every time I restart my work MacBook.

Is there a terminal command or something I can set to stop Hot Corners settings from resetting back on constantly? I'm guessing my company has defaults that they apply that override the settings on restart.
Yes, there are some terminal commands to set your default setting to "none".

Disable top left hot corner:

defaults write com.apple.dock wvous-tl-corner -int 0


Disable top right hot corner:

defaults write com.apple.dock wvous-tr-corner -int 0


Disable bottom left hot corner:

defaults write com.apple.dock wvous-bl-corner -int 0


Disable bottom right hot corner:

defaults write com.apple.dock wvous-br-corner -int 0


In the “wvous-XX-corner", for the XX, tl is top left, tr is top right, bl is the bottom left, and br is the bottom right.

For the numbers at the end, “0” is nothing, “1” is disabled, “5” is start screen saver, “2” is Mission Control, “3” is Notifications”, “4” shows the desktop, and so on.
