4k YouTube on Safari macOS Big Sur I just updated my mid-2014 MacBook Pro to Big Sur and I thought one of the features was the ability to watch YouTube videos in 4k now. However I don't see that option for any videos that I know are 4k. How do I enable it?
Try to go in Safari Settings &gt; Advanced &gt; Enable &quot;Show developer menu&quot;.
In the developer menu enable &quot;VP9 SW decoder&quot; and &quot;VP9 SW decoder on battery&quot;.
Apparently, some older Mac doesn't support 4k on Youtube, you can still try to play them with Google Chrome.
