I am currently running Mac OS X 10.8.4. This morning I had a blocked plug-in message on YouTube, so I tried to install the latest version of Flash. After installing, I was still getting the blocked plug-in message, so I completely uninstalled Flash and tried to reinstall it. Now YouTube is telling me that I don't have Flash at all. I have tried to reinstall twice now and am still unable to get Flash onto my computer.
Can someone please help me?
Spotlight Search Flash Player.plugin
Search your Mac HD
Trash EVERYTHING that appears in the results.
Empty the Trash, then follow the instructions here: How to perform a "clean install" of Flash Player in Mac OS X
