The way to activate the hot angle of your Mac is to go to "System Settings" → "Desktop and Screen Saver" → click the "Hot angle..." button and select the trigger action for each corner. Common combinations include setting the upper left corner as Mission Control, setting the upper right corner as the desktop, setting the lower left corner as the launcher, and setting the lower right corner as the screen saver. Hot angles are suitable for quick switching tasks such as quick return to the desktop or viewing all windows. External monitor users need to manually adjust the home screen position to enable multi-screen thermal angles. Pay attention to avoid mistouching when using it, especially when working in full screen or conflicts between multiple desktop management tools, the hot angle can be temporarily turned off or the settings can be adjusted.
Activating Hot Corners on Mac is actually very simple, the key is what you want to do with them. Although the system comes with small functions, it can significantly improve operational efficiency after reasonable settings.

How to turn on and set the hot angle
Open "System Settings" → "Desktop and Screen Saver" → Click the "Hot Corner..." button in the lower right corner to see the settings options in the four corners. You can select a trigger action in every corner, such as starting screen saver, displaying desktop, entering Mission Control, etc.
Common combinations include:

- Top left corner: Mission Control
- Upper right corner: desktop
- Lower left corner: Starter
- Lower right corner: Screen saver
After the setting is completed, you only need to quickly move the mouse pointer to the corresponding corner, and the set action will automatically trigger.
Common uses and suggestions
The biggest advantage of hot angle is its speed, especially suitable for those who switch tasks frequently. for example:

- Want to get back to the desktop quickly? You don't need to press command F3 or click on the desktop icon, just throw the mouse to the upper right corner.
- Need to quickly enter Mission Control to view all windows? Just touch the upper left corner to get it done.
- If you don't use screen savers often, this function is actually more suitable for fast screen locking. It will be more practical in combination with the "Start Screen Saver" and "Password Required" settings.
If you are an external monitor user, note that by default, the hot angle only takes effect on the main monitor. If you want to use hot angles on multiple screens, you need to manually adjust the home screen position in the display settings.
Things to pay attention to when using
Not all settings are suitable for everyone, and some features may affect the experience instead. for example:
- If you often work in full screen, it is not recommended to set the hot angle other than "no operation" to "screen protector" because it is easy to touch by mistake.
- If you use multi-desktop management tools (such as BetterTouchTool), it may conflict with hot angles and you need to pay attention to priority.
- Moving the mouse too fast can sometimes cause mistaken touch, especially during game or drawing. At this time, you can temporarily turn off the hot angle or change the key combination method.
In addition, the thermal angle is more helpful to the touchpad users, especially those who are used to pulling out Mission Control with one stroke of the four fingers. The two can complement each other.
Basically that's it. There are not many settings, but it can save a lot of time if used properly.
