Videos can't play
Whenever I try playing any videos of any sort, even videos on Youtube and videos I've already downloaded, it doesn't play.
On youtube, the video just pauses right after I play it, and I can't press play anymore, and it heats up my macbook like crazy and uses a lot of cpu power.
For the videos I've downloaded before, it just skips the entire thing and shows the last frame of the video.
