If you use Macintosh and either Navigator or Explorer

• Click on the Get Shockwave button below.
• At the Download Center, click on Download Now
• You’ll be asked where you want to save the installer. If you don’t have a folder you can easily remember, download it to your desktop.
• Write down the name of the installer, in case you need to search for it later
• You might have two or more Shockwaves on your desktop. If you see extensions .sit or .hqx, these are compressed files that are used to transfer files over the Internet. You can just throw these away. What you want is an application called Flash Player Installer, it usually has a purple icon.
• Quit your browser and double-click on the Flash Player Installer.
• In the dialog box, choose the browser you normally use (some computers have more than one). Of course, you should install it on all of your browsers
