Bottom Line
Adobe Flash Player For Mac 10.5.1
If you're constantly visiting Flash-based Web sites, you will have to install either this plug-in, or a browser like Google Chrome, which has built-in Flash support. Generally, the better way to go would be to use Chrome since there will be a lower performance impact on your system. But if Chrome is not your kind of browser, then this plug-in remains a viable solution for enjoying Flash content on your Mac.
