In addition to looking under the hood for your plugin files, you can check Safari's 'Installed Plug-ins' menu (found under the Help menu) to see if it includes a 'Shockwave Flash' item for proof that you've got the plugin installed. In addition to the current version available,
this Adobe Flash Player web page will also show the version you've got installed in a small Flash window labeled
Version Information. The advantage of doing this in a Flash window is that seeing it provides implicit proof that the plugin works as intended, a handy troubleshooting aid. As a Flash user, you might want to bookmark this page, plus its link to the Flash update page you might also need.
