Flash video causing 105% CPU usage spikes

if you only have the problem with Flash then it begs the question, could that be the problem. not Snow Leopard etc.

Look at the World of Warcraft Mac Support. There are people having the same issue with WOW. Its a video issue. Blizzard won't touch this problem because its a Mac problem.

Apple is famous for DUST under the iMac and iPhone...

They build this stuff in China with no QC whatsoever...

Very sad considering the price you pay... I have had my fair share of dust under the LCDs

I don't know about a permanent solution, but I do know a good fix for now (for youtube flash videos mostly) until apple takes care of it. There is an application called click2flash which replaces the default flash youtube player with one that plays the H.264 version of the file. It takes a tiny bit longer to load videos, on my MBP on wifi at least, but it won't make a dent on your CPU. Hope this helps all the youtubers with this issue.

Don't even deal with applecare. Just return the machine. With an issue like this, anyone will return it, if not, just alert the manager, they can override the restocking fee because of the issue.

I've been having slowdown issues since day one (last Thursday) with this machine. It is not caused by Flash at all.

The machine works great for 20-30 minutes, but eventually everything gets sluggish.

I've been using my Unibody Macbook as my backup all week because I can't take the slowdown.

I'm having the same slowness issues even if I don't play any Flash video. Firefox starts using all the CPU's power (100%) from one core. Doing anything within the browser creeps and is very sluggish.

The only why I found to temporary resolve the issue is to either restart or have the system sleep by pushing the power button.

This is a problem that Apple should be looking at ASAP. Lets hope they are.

The problem is caused by air port. Plug your computer directly to your router via ethernet and it will fix the problem.

Interesting...turning AirPort off and on clears the CPU usage back to normal. This is an interesting issue that I have never seen before.

Just a quick note. I too have had all the problems everybody has mentioned but I noticed after I installed windows 7 through bootcamp the computer works fine! Absolutely no slow downs or sluggishness whatsoever. This tells me in my case anyway that it's not a hardware issue but a software/driver issue in snow leopard.

Hi all, I am having the same problems.. thought it rather weird to be experiencing so much slowness with a brand new Mac. Kind of got me upset at spending so much.

Purchased in France at an APR Store
Bought my new 27" Core 2 duo, 48 hours ago. Updated everything, build : 10A2155
Running Snow Leo 10.6.1
Shockwave Flash 10.0 r32

I did not transfer my old data.

It happens even if flash is not in use, I'm not a video watcher.

You're all reporting high CPU usage, in that case anyone having this issue should look at Activity Monitor which process(es) is/are using the CPU.

For that, you open Activity Monitor, and you order the processes list by "CPU %". Then give here the process(es) name(s).

As of now it seems that it's related to Flash. Also some report that even after Flash being killed or stopped to use the CPU, the computer remained sluggish for some times. Then it may well be because Flash used also a lot of RAM additionally to CPU. You can check that also on Activity Monitor.
If Flash use a lot of RAM and fill the RAM, the system will have to swap in and out to get some fresh air. In that case, the system get quite slow for some time. You can observe that for example when using VMWare or Parallels Desktop and assigning too much RAM to the VM (like assigning 3GB when you have 4GB of physical RAM).

If it's really Flash related, my advice is to report it to Adobe, and to remove the Flash plugin altogether (cf /Library/Internet Plug-Ins) and wait for a Flash plugin revision.

Strange to see the discussion in this thread coming to different conclusions to the [previous thread on the same topic!|http://discussions.apple.com/thread.jspa?threadID=2134215]

I have found that Installing the [ClickToFlash plugin|http://rentzsch.github.com/clicktoflash> suggested in that thread provides a workaround.

Do all of you have the 4670 or the 4850 card?

NO DOUBT.
OSX 10.6 + Safari problem.
When I upgrade 10.6 from 10.5 on same machine, I see a big difference on flash player performance under same full screen flash website.
Use another browser would solve the problem.
It doesn't related to new iMac, it is related to the safari, I have lot of mac here have the same problem including MacPro 8core.
