What does Apple have that compares to Adobe flash player ?

Question

What does Apple have that compares to Adobe Flash Player, I keep getting Blocked plugged message and it tells me to download Adobe Flash Player and when I do nothing happens.  Also when I purchased my iMac it came with Leopard osx system, last year I installed the Snow Leopard 10.6.3 system and since then cannot read CD's or DVD's from PC or my husbands new iMac with Mountain Lion system.

There is no equivalent to Adobe's Flash Player. You either have it installed or not. For the reasons outlined below, Apple no longer sell Macs with Flash Player pre-installed, you have to obtain it from Adobe.
Flash - Apple's official position:

Flash v. HTML5

Apple may have more reasons behind not installing Flash by default other than the stated reason of ensuring that users always have the most up-to-date version. Having Flash installed can cut battery runtime considerably—as much as 33 percent in our testing. With a handful of websites loaded in Safari, Flash-based ads kept the CPU running far more than seemed necessary, and the best time I recorded with Flash installed was just 4 hours. After deleting Flash, however, the MacBook Air ran for 6:02—with the exact same set of websites reloaded in Safari, and with static ads replacing the CPU-sucking Flash versions.

You can check here:  http://www.adobe.com/products/flash/about/  to see which version you should install for your Mac and OS.
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):

and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.
