Uninstall Flash from a Mac

Adobe’s Flash Player is known to cause a slew of issues, slowdowns, battery drain, crashes, and other problems for Mac OS X. If you’re fed up with Flash, you can ditch it by choosing to uninstall the Flash player and entire plugin package from the Mac. There are a few ways to accomplish this, but we’ll cover the simplest approach that uses the Adobe Flash Player uninstaller application, which is a fairly automated process.

How to Uninstall Flash from Mac OS X

You can always choose to remove the associated files on your own, but it’s significantly easier to just use the official uninstaller application from Adobe, thus we’re going to focus on that for the purpose of this walkthrough. When you’re ready to remove Flash from the Mac, proceed:

  • Quit all open web browsers
  • Download the Adobe Flash Player Uninstaller application from Adobe directly by clicking here
  • Once the Uninstall Flash dmg file has downloaded, mount the disk image, and then launch the “Adobe Flash Player Uninstaller”
  • Click on the “UNINSTALL” button at the splash screen
  • Enter your password when asked
  • Let the application run to completion, and when finished click on “Done” or just quit the app

Once out of the Flash Uninstaller app, Adobe recommends taking one further step and manually clearing out the following directories as well:

~/Library/Preferences/Macromedia/Flash\ Player
~/Library/Caches/Adobe/Flash\ Player

These folders are both within the users Home directory ~ and can be access directly or from the Go To Folder command with Command+Shift+G and pasting them directly. Adobe also recommends rebooting the Mac afterwards to clear caches and complete the removal, though that may not always be necessary depending on the version of OS X.

Now Flash is completely uninstalled from your Mac. You may want to go one step further and delete your Flash cookies yourself, since the app doesn’t always grab them on the way out. This insures that you don’t have any residual files laying around.

Keep in mind that uninstalling the Flash plugin from the Mac does not effect sandboxed Flash Player plugins like what is implemented in the Google Chrome web browser. However, this removal process does uninstall Flash from Safari, Firefox, old versions of Chrome, and throughout OS X in general. The way that Chrome handles Flash through a sandboxed plugin within the app is fairly safe, plus it automatically updates, so it makes it perhaps an ideal way to keep Flash around on a Mac if you do need to occasionally use the plugin or player for various websites. Users of Chrome can also choose to selectively allow Flash to run only when allowed by using the excellent Click-To-Play feature that is built into modern versions of the Google web browser.

Personally, I keep Flash Player installed but just use a Flash blocker so I can only activate Flash when I need it. I also use Chrome and the ClickToPlay feature to further control how and when Flash activates. Yes, it can still cause problems from time to time, but it’s not nearly as bad as when Flash is allowed to run rampant on a Mac. Nonetheless, removing the plugin from OS X is a completely viable solution for many Mac users, and fortunately is an easy task to complete, but also to reverse should you decide at a later date that you do need the Flash player on the computer.

    … even after uninstalling you can cheat looking at Flash content with Google Chrome as it has its very own embedded Flash plugin ;)

      This is what I do.

      With the YouTube 5 and HTML5 Audio plugins installed in Safari, I can get by, and for anything else I use Google Chrome.

      The advantage is that webserver logs show that no flash is installed when I visit a site, and higher traffic like that will help encourage use of HTML5 alternatives to flash. Since ClickToFlash reports itself as a flash-compatible player, that will not have the same effect.

        For clarity, I don’t have a problem with people using ClickToFlash over my method, I just want people to be informed.

    Uinstalling it completely is a bit of overkill. That’s like uninstalling a GPU rendered game because it kills battery life.

    Flash, like anything that takes a lot of resources if need be, will hurt battery life WHEN YOU RUN IT.

    It does not inherently do anything to your computer. Think running HTML5 videos through your GPU via hardware acceleration doesn’t hurt your battery life? Think again.
