MacBookPro with Safari.

  Safari hasn't supported >1080p in years (because it blocks VP9 and Youtube has stopped offering higher resolutions in H264 that Safari supports)

    Yup. Golden rule: don't use Safari for YouTube (or really for video content in general).

    Blocks VP9? Maybe it doesn't support it but blocking would imply it is built-in but forcibly disabled. It does look like they're testing it since it's in tech preview [1] so once it's relatively-bug free they'll probably release it.
