Hi Chris, Flash is on the way out and you probably know about Apple's aversion to Adobe's Flash Player Plugin. Steve Jobs went on record to say that it is a dying technology and Apple actively prevents Flash in any form from appearing on any iOS-based devices. HTML5 is the new technology.
In Mac OS X 10.7 & 10.8 operating system, the Flash Player plugin is not part of the default install. If you visit a website like YouTube using Safari in Lion or Mountain Lion, it will warn you to 'upgrade your Adobe Flash Player to watch this video'. Should you though? The answer depends on how often you intend to use the plugin and how resource-constricted, particularly in the CPU department your Mac is. Three ways to block, or reduce, Flash usage on your Mac. 1. Leave it uninstalled 2. Use it on an 'As-required basis Extensions like 'ClickToFlash' for Safari, FlashBlock for Google Chrome & Firefox make sure that any Flash content you come across is blocked UNTIL you explicitly give it permission to load. Or 3. Block it whenever you feel like it. If you want even more control over Flash playback, consider using a Menubar app like FlashBlock or FlashFrozen, both of which are available on the Mac App Store for $1. These plugins sit in your Mac's menubar and take the reins of the systemwide Flash plugin in their virtual hands, ready to stop it short on your command.
