This step-by-step guide will take you through the process to completely uninstall Adobe Flash Player from your Mac. The regular removal of unwanted and unused software will clean up your Mac and keep it running smoothly.

What is Adobe Flash Player and Why Remove it?

Flash Player is a browser plugin that enables the user to stream and watch video (on sites such as YouTube), viewing multimedia content, and interacting with RIA (Rich Internet Applications).

As of 1 January 2021, Adobe will not be offering and updating Flash Player anymore. Web browsers will rather be making use of the advancements of HTML5, WebGL, and WebAssembly, therefore negating the need for Flash Player.

Method 1. Using Adobe Flash Player Install Manager

I dusted off an old Samsung Xpress m2020w laser printer that I used to have connected wirelessly for WIFI printing. Now with Catalina, the Samsung Easy Wireless Setup program doesn't work. I can print with a wired connection. How can I connect my printer to my network for wireless printing if Cata. Open Safari, and choose Safari Preferences. Click the Websites tab and scroll down to the Plug-ins section. Locate the Adobe Flash Player entry. Click the checkbox to enable Flash Player.

Because Adobe Director Projectors are 32-bit applications, SPR for Mac will not work on MacOS Catalina or Big Sur. This means that Flashpoint for Mac does not support Shockwave games on Catalina or Big Sur. MacOS Big Sur (MacOS 11.0) Flash applications have been successfully tested and are working. Starting with Firefox version 62 for Mac, Adobe Flash applets will be run in a more secure mode using process sandboxing. The sandbox is known to prevent the following features from working: Print to PDF from the Flash print dialog Print to Open in Preview from the Flash print dialog Quicklook in the File - Open menu Saving files from a Flash.

By far the most effective and cleanest way to remove Flash Player is by making use of the Installation Manager. This simple process will ensure all relevant Flash Player files are removed.

Locate Adobe Flash Player Install Manager on your Mac

1. From the Menu bar at the top of the screen, click on Go and select Utilities. If you can’t find Utilities, it also appears in the Application folder.

2. Right-click on the ​install_flash_player_osx.dmg​ file and select ​Move to Trash​.

Method 2. App Cleaner and Uninstaller

One of my favorite applications for my Mac is App Cleaner and Uninstaller. Not only does it assist you to quickly uninstall unwanted applications, but it also helps you find remaining files that are hard to find.

Launch App Cleaner and Uninstaller

Open the App Cleaner and Uninstaller App from the Applications folder by double-clicking on it.

Remove Flash Player files

1. Once opened, find Flash Player in the left-hand pane and click on it.

2. On the top of the right-hand pane, check the box next to Select All. Then click on ​Remove​ in the bottom right.

3. A window will appear to review and confirm the selection to be removed. If you are happy with the selection, click on Remove in the bottom right to proceed.

4. App Cleaner & Uninstaller confirms that the files selected were successfully removed.

5. Unfortunately, all files related to Adobe Flash player could not be removed, because we are running the free version. Upgrading to the Pro version will allow you to remove it completely.

However, App Cleaner & Uninstaller does show in which directories the remaining relevant files are stored. Similar to Step 3, select Flash Player from the left pane.

6. While hovering over the first file (Flash Player.prefPane) in the right pane, click on the blue arrow icon.
