I’m running an imac 5k from late 2014. A few weeks ago, I was watching a movie on the apple TV app (not the device) on my imac. I started to notice that after about 2 min, the audio and video started to drift apart. Pausing the video briefly and then restarting fixed the issue for a couple of minutes and then the problem came back.
Today, the problem got really bad with Safari watching YouTube. After about 30 seconds the video becomes unwatchable. I checked Vimeo and the same thing happened. So it’s not just the AppleTV app or the website. Since this is also happening in AppleTV app, I’m wondering if it has something to do with some Apple software.
Now, when I watch YouTube with Chrome, there is absolutely no problems at all.
I’m stumped. Any ideas as to what could be going on?
