After reading Engadget's report citing recent complaints about Flash video playback mucking up system resources on the latest 27-inch Apple iMacs, we decided to test out the claims using our own system. Users on the Apple Discussion threads noticed a bug in the Flash Player that bogs down CPU processes, resulting in choppy audio and video playback.
We visited several sites with heavy streaming video content like Hulu, YouTube, and the Break Media Network, and experienced similar issues: popping sounds and jerky video rendering the content unwatchable on several accounts. Like many of the users in the Apple thread, we called up the Activity Monitor and saw that the Flash Player demanded a surprising 114.4 percent of the iMac's CPU processes.
We were able to temporarily fix the problem by putting the computer to sleep and waking it up, but some people are speculating that a hardware malfunction could be to blame. We've also tried to contact Apple for official word, but our messages have been as yet unreturned.
If you're experiencing similar problems, we'd like to hear about it--leave a comment and let us know the issue and what you did to fix it.
