There have been issues reported with the 13.0.0.182 version of the Flash plugin crashing on some older Mac computers due to the compiler generating incompatible code. The only way to recover is to uninstall the Flash 13 version and revert to an older Flash version and wait for Adobe to release an update that addresses this issue. * http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html The latest Flash 11.7 version, available via this link, is recommended in this case because it has the latest security patches. * http://www.adobe.com/special/products/flashplayer/fp_distribution3.html ----- Adobe Community: ATTENTION MAC CUSTOMERS - Flash Player 13 "Plugin Failure" Workaround: * http://forums.adobe.com/thread/1447282
