Apple Releases Tenth Beta of macOS Big Sur to Developers

[CopyChief]

I had this issue as well, but someone had posted a solution for it. Turn on the developer menu in Safari and then in the Develop tab -> Experimental features -> VP9 SW decoder on battery - enable

This fixed it for me and YouTube videos immediately play. Supposedly it also turns on 1440p and 4K in YouTube, but haven't tried it yet.

This also fixed it for me (2015 12" Macbook), even though I'm not running on battery. Ah, betas.

Where did I say we were using it on the daily?

Perhaps your company should not use beta software as their daily OS

Teams alert window is working in Beta 10?

 

[tuzzanti]

No, it is not fixed. And we are seeing awful graphic performance and fan noise on 13inch and 16inch MBP's with or without eGPU's.

Also did the trick for me even though I was not running on battery. Go figure!

Stable OS > release a new OS because I am bored.

don't see that in the menu - MBP 2017

don't see that in the menu - MBP 2017

You need to enable the developper menu in Safari Preferences first.

Safari Preferences -> Advanced, and check enable developper menu.

Did you scroll down, I can see on 2014 MacBook Air

Public Beta now available

 

[Realityck]

Thanks downloading now. Hope Safari oddness with graphics driver is fixed. (quits unexpectedly)

 

[jz0309]

downloading public beta now

 

[Blackfield]

If you have less than 10gb free space it says that you have to check your internet connection to download. But when I freed 5gb more, then it downloads. So it's a free space issue not an internet issue. Just a heads-up.

 

[gimarbazat]

Installing the public beta now. The 3.8 gb took less than a minuet to download

This is what I see on my Mid 2015 MBP

Odd that you don't see it.

Maybe your MBA doesn't support VP9 or VP9 is dependent on another feature that isn't checked.

 

[gimarbazat]

boy these new background photos in beta 10 do look great on my 2 display XDRs on my hackintosh.

Maybe try with Safari Tech Preview to see it behave the way, I think your Mac should support it, it's Pro so there is something going on.

Never had option on, but it won't go away

I toggled the setting on and back off in System Preferences/Users & Groups, and the menu went away after that.

Thanks, somebody else mentioned seeing that full installer about 6 hours ago, and I snagged that then.
