Last week there were several reports that users on the new 21.5″ and 27″ iMacs were having issues playing Flash-based video. By the end of the week, most of the posts and forums had resolved themselves to believing that the issue wasn’t limited to Flash Player, but appeared to be an issue with the AirPort driver.
Apple released the Mac OSX 10.6.2 update yesterday, and the release notes state:
“this 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”
If you’re having video playback issues on your new iMac, try the 10.6.2 update. If you still have Flash Player issues after the update, please file a bug.
