By default, your Mac shows some of your most recently run apps in a special area of the Dock. If you want to hide this history, it’s easy to turn off the “recent applications” area in System Preferences. Here’s how.
First, click on the Apple icon in the top left corner of your screen. Select ‘System Preferences’ from the menu that appears.
In System Preferences, select ‘Dock & menu bar’.
In the preferences of ‘Dock & menu bar’, uncheck the box ‘Show recent applications in Dock’.
The recent applications area will immediately disappear from your Dock. Close System Preferences and you will see the result. Nice and clean!
If you change your mind and want to re-enable the recent applications area later, simply go back to “System Preferences”> “Dock & menu bar” and put a check next to “Show recent applications in Dock”.

Manually delete recent apps from the Mac Dock
If you want to keep the recently used apps feature active, but still want to occasionally hide one or two specific apps from the dock, this is easy to do. Just click the app’s icon in the recently used section of the Dock and drag it to the center of your screen. About halfway down the screen, the icon will turn translucent and you will see a “Delete” message.
Release your mouse button and the app will disappear. You can do this as many times as you want, but of course new apps will be added to this part of the dock all the time unless you turn it off using the steps in the section above.
By the way, did you know that you can quickly resize your Dock by hovering and dragging your mouse pointer over the divider line next to Trash? It’s pretty useful.
