Youtube not working with Safari

[mxrider88]

Youtube stopped working on Safari on BigSur beta 10. It works with chrome and firefox. The ADS load, the videos give me an error and won't load. Tried everything, cleared cache, reboot, deleted wifi plist files, nothing.
Anyone else with the same issue?

Cheers

Dunno if this will work but you can try deleting safari plist.

~/Library/Containers/com.apple.Safari/Data/Library/Preferences/com.apple.Safari.plist

Yep! But chrome works and Firefox too.

On safari, try going to Develop tab > Experimental features > disable VP9 decoder, and then restart Safari.

Working for me on my MBP 2017, I've not messed with any settings. All videos play on Safari.

This worked for me, but was hyped for the 4K YouTube playback... so sad

edit:
I re-enabled the VP9 decoder, as well as VP9 SW decoder on battery (which wasn't active) and now everything works just fine!

Having the same issue here. I haven't tried any of the proposed solutions but glad to know I'm not alone here.

You nailed it my friend! Thanks!

You're welcome dear friends.

For me, re-enabling the VP9 decoder ánd enabling the VO9 SW decoder on battery made it work for me, and even let me watch 4K YouTube 😬 (on my 2014 MacBook Pro at least)

Is YouTube working again in safari on the latest beta?

Apparently so:

MacOS 11.0.1 beta news article

Which means my comment in the other thread was incorrect about it being something YT had to fix! I can't confirm, as I never had the issue.
