Heya. I've been searching around google, but all I can find are two year old threads. Basically, I have a 2011 MBP, and I installed Flash on it. Thing is, whenever I actually load up a video like on youtube or something, Safari just hangs and becomes unresponsive until after the video has completely buffered out, and even then the playback is sometimes choppy. Restarting the mac or reinstalling flash fixes it for a little while, but the problem always comes up again. Is this a common issue? What can be done?
