I'm trying to fix the discontinued Flash player. Here are the instructions. How would I get to this Library folder?
1. Create a new folder on your desktop, name it OLD FLASH (or anything else).
2. QUIT SAFARI, or what ever browser you are using.
3. Open your internet plug ins folder, located in the root of your directory at
~/Library/Internet Plug-Ins, (not the user directory with your name)
4. Move the OLD plug-in called "Flash Player.plugin" out TO the folder you created
earlier, for safe keeping.
5. Move the NEW plug-in you downloaded INTO the Internet Plug-Ins folder.
Note: You may need to restart the computer. But you may not have to. You may
also have to reset Safari, but test it before you reset.
6. Launch Safari and test the videos that did not work before. It should work now!
