I often have a problem with YouTube on my iMac it loads the site, but where the video is supposed to be, there's just a black box with no controls. Just plain black. Kill safari ?? It always work with chrome. Only reason I stick with safari is, that i can make the bookmark line text only. You cant do that on chrome and I hate the mess with the logos :-/ Is it safari that hates Youtube because it's google ? Or what can be wrong.
