How To Uninstall ResizeIt

1. The standard and easiest way to uninstall ResizeIt:

First, we need to make sure the app isn't running, so lets open Force Quit (from the Apple menu on the top left of your screen) and terminate the app if you see it running:


 - Now, open your Applications folder.
 - Right-click on "ResizeIt".
 - Click on "Move to Bin" (or "Move to Trash" on older versions of macOS)

2. How to remove ResizeIt using the Terminal:

 - Open the macOS Terminal from Applications > Utilities.
 - Type killall ResizeIt, hit ENTER
 - Type rm -rf "/Applications/ResizeIt.app", then hit ENTER.
 - If that fails, try typing sudo rm -rf "/Applications/ResizeIt.app"
 - Now type rm -rf ~/Library/Caches/sekn.resizeit, hit ENTER.

This will remove ResizeIt from your Mac, but some supporting and related files will be left behind. Read on for the best way on how to remove those.
