When I try to change the video resolution in YouTube, the screen goes black and it automatically goes to 240p regardless of the resolution that I choose. It will play the video so long as it remains in its default resolution i.e. 360p or 240p. I also have Chrome downloaded and it has no issue changing between video resolution so I am assuming it is an issue with Safari. I reinstalled Flash and I tried resetting the computer but had no success with either of those attempts. Any ideas?

    Same thing, except it defaults to the highest resolution. I try to load the video, it takes forever, so I try to downgrade the quality, hoping it will load, but it flips back to the highest, and if I refresh the page, it does it again...

    Thanks dschinkal! When I view You Tube clips on Safari and click the resolution adjuster to increase it (say, to 720), the screen goes black and I have to click refresh in order to reload the page. After which, it plays again at a low resolution.


    This has happened since I bought my new iMac 27" a month ago.
