With macOS Sequoia, how do I fix Hot Corners to only active when the mouse is in the corner?!?!

FWIW, I have 3 Macs with Sequoia 15.1 installed. I have to have the cursor within a few pixels of a corner before it will trigger an action. As you can see from my screen shot it is certainly closer than 2 inches.

You can try booting into Safe Mode then restart normally. Sometimes that will fix anomalies.

Before macOS Sequoia, I'd active Hot Corners by going to the corner of my screen. Now, if my mouse gets even near the corner, like 2 inches from the corner on my screen, Hot Corners sometimes activates. (sigh) I have a Hot Corner in the top left to lock my screen, so if I try to press the "previous page" button in Firefox for example, that's apparently close enough for Hot Corners to activate and lock my screen. Likewise when I have Word or Excel open and try to click buttons in the top left of the menu bar for those applications, Hot Corners activates and locks the screen. My mouse is absolutely not in the actual corner when Hot Corners activates.

How do I get hot corners to function how it previously did, where I needed to move the mouse to the actual corner itself to activate it rather than just be near the corner?

You can Lock the screen easy enough with Control Command Q

in the mean time To be proactive you can file a bug report / submit your Apple Feedback here:
