We have a full tutorial available with detailed steps for how to remove Flash Player from macOS. In the Finder window that opens, scroll down to the “Devices” section and click “Uninstall Flash Player”. Is the Flash Player installer window not appearing after you’ve opened the downloaded Flash uninstaller? If so, then click the Finder’s Go menu and choose “Desktop”. To open the uninstaller, double-click the file in the Downloads window. “We’re proud that Flash had a key role in evolving web content across animation, interactivity, audio and video - and we’re excited to help lead the next era of digital experiences,” it reads. By default, the uninstaller is downloaded to your macOS account’s Downloads folder.
