Flash gala does not work on my iMac 21.5 with 9400m

Dear all,

I found that the Flash gala does not work on my iMac 21.5 with 9400m. I cannot see the white square box when I play 1080p video on youtube.

Is there anyone having the same issue? It seems that Apple does not make use the 9400m in iMac 21.5.

If you are using the same model with the Flash gala working, please let me know.

Thanks every one.

Is there anyone having the same problem?

Please feel free to reply even you do/do not have the problem if you are using iMac 21.5.
