Last month we blogged about a bug marring Flash playback on the latest 27-inch Apple iMacs. Users on several Web sites, including the Apple Discussion Threads, noticed a problem with the Flash player that caused choppy audio and video playback, but it appears that the newest Mac OS X v10.6.2 update fixes the issue that was apparently caused by a conflict with the Airport driver.
According to Apple, the update "addresses video playback and performance issues for iMac (21.5-inch, late 2009) and iMac (27-inch, late 2009) computers that may occur in some situations while AirPort is turned on." Since our own 27-inch iMac also experienced slow Flash streaming and intermittent sound hiccups with the AirPort turned on, we downloaded the 10.6.2 update and left it to sleep overnight.
Prior to the update, the Flash Player consumed 114.4 percent of system resources, but 24 hours after the update we're happy to report 26.8 percent usage in the activity monitor and smooth performance across all popular streaming video Web sites like YouTube, Hulu, etc.
Much thanks to the Apple Forums and Apple itself for quickly addressing the needs of its community. If you haven't updated yet, simply choose Software Update from the Apple menu to install OS X v10.6.2.
