Hi all, So I picked up my brand new 2015 MacBook 1.2/512 and so far I'm pretty happy with it. However I've come across a weird video playback issue. Whenever I try to load a video on either IMDB or Tumblr it struggles. It can just about load an SD video but trying to load an HD video it takes forever to load and once it does it will play the first few seconds then get stuck. Sometimes the sound will continue playing and the progress bar will continue but the video is just stuck and overall the experience is stuttery when viewing videos from these two sites. On the flip side of that I can play 4K video on YouTube fine... I'm on 10.10.5 running safari. Can anyone else replicate this issue? I've tried chrome and it's no better unfortunately. I want to believe it is a software issue so very much but if this awesome little machine is too underpowered to play even an HD video I will be super bummed.
