If you are experiencing this annoying issue: the Dictionary keeps popping up when you type or use the mouse on your Mac, here is the solution for you.
The issue appeared on my MacBook Pro all of a sudden, I had no idea what I did. I was just typing to type on a Google doc and some words got automatically highlighted, followed by a Dictionary app showed up providing a definition of the word the mouse pointed at. And my screen sometimes enlarged by itself.
At first, I thought it was that I haven’t updated my MacBook to the latest macOS, so I went ahead and updated. But the issue still persisted.
It’s actually quite simple to disable dictionary from popping up on Mac. All you need to do is uncheck an option in the trackpad setting.
Step 1: click on the Apple icon on the top left corner, then select System Preferences.
Step 2: click on Trackpad.
Step 3: under the Point & Click tab, uncheck the Look up & data detectors option.
That’ll do it. Now the annoying dictionary keeps popping up issue should not re-appear.
Quite simple, right?
Not sure how I mistakenly checked this option. My guess is that I might have mis-clicked it while I was cleaning my Mac screen and keyboard.
Anyway, hope this tip has helped you out.
