Anyone else spend a lot of time on YouTube and notice YouTube buffering a hell of a lot more on Yosemite? I mean, it's always had it's dodgy periods and buffered a lot at times but I swear it feels like it's got so much worse since installing the Yosemite PB2. So much so that I'm considering returning to Mavericks till release. I'd like to see if anyone else has the issue first though so I can be sure it's not just YouTube misbehaving the past couple of days. I mean, I've tried out Yosemite now and honestly won't be heartbroken to go back to Mavericks. It won't bother me much at all. I can wait for Yosemite. That being said going back and restoring Time Machine backups will be time consuming so if nobody else can confirm it's Yosemite it'll be a waste of time to go back to Mavericks and still have the same problems.
