YouTube not working after updating to Safari 27.0

I also have after updating on MacBook Air 2020 i3 to macOS 15.8 and after that Safari 27.0 stopped playing any videos, just the page hangs. I deleted the entire cache, extensions, etc., nothing helps. It's a shame, because I used it to watch video content

I'm having this exact issue. MacBook Air 2020. Updated to Mac Os Sequoia 15.8. Safari 27.0. YouTube won't work. Plus, videos and graphics won't load on other websites. Yes, I've cleared caches. Yes, I've restarted. Tried the fixes suggested below. Not using a VPN.

Ever since the last updates my YouTube music player won't work properly. It plays the first song okay but has trouble moving to the next song in an album. I've tried all the usual "clear cache" and other tips - but this is clearly happening after the latest OS update.

Exactly the same problem and exactly the same hardware and software config here. MacBook Air 2020, 15.8, 27.0.

YouTube hangs and Safari Graphics and Media immediately goes to >99% CPU.

Yes, I've cleared all website info for Google.com and YouTube.com. No luck. Amazing fail, Apple.

Same here ! Safari 27 MacOS 15.8 on MacBook Air 2020 (Intel). I can not watch videos on Youtube.

I think the problem is MacBook Air 2020 (Intel) itself.

I’ve never seen another model with so many issues (especially fan problems and overheating).

We had no way of knowing this when we bought it.

I still can’t understand why they haven’t recalled this model and given us a computer with an Apple chip.

Well, I updated to Sequoia 15.8.1 today hoping that Apple had taken notice and offered a resolution to the self induced problem with Youtube ........ result : Negative, You Tube still locks up and refuses to refresh. Any suggestions that my configuration could be the cause. of the problem does not take into account that the machine worked just fine and dandy before Apple inflicted the update upon us, therefore it would appear to be an Apple problem and up to Apple to resolve it. Otherwise, will Apple provide us all with replacement machines that work? That will obviously be a huge NO.

I updated Sequoia on my Mac and now YouTube will not play on Safari. It works on chrome but when using chrome my CPU usage is much higher than on safari and my computer fan goes on (doesn’t happen on safari) I see many others here have the same problem. Has Apple offered any support for this issue?

This entire problem for legions of hitherto Mac / Apple enthusiasts is a classic demonstration of 21st century Corporate Arrogance. Apple created the problem and now ignore it perhaps in the hope that we will all abandon the Intel driven Mac Book Air. Maybe Apple would prefer that we all went backwards to Microsoft? Personally speaking, after more than 20 years of Apple laptops I am seriously considering alternatives, due entirely to the utterly disgraceful lack of support shown to loyal supporters, not to mention the several £K spent on Apple products over the years.

It’s been nearly a month and one update, yet the problem still hasn't been resolved. Many people work with video on Macs and are now forced to temporarily switch to other browsers. It’s just not professional.

Same Probleme here on an Macbook Pro M2 Pro. In the past Youtube worked almost all the time in Safari and Firefox. Than after deleting the cash and brwoser Data in Firefox somehow Youtube won't work at all.

Yep, I can also confirm Youtube has been broken for me ever since I updated my MacBook Air 2020 to Sequoia 15.8, and Safari to 27.0. Refuses to load videos, and crashes. Guessing I'm out of luck watching Youtube in Safari until Apple releases an update?

Today I updated to Safari 27.0, and now YouTube won't work. The page loads, but when I click on a video either nothing happens, or it tries to play the video but never does. I've restarted and cleared cache, but still no luck.
