So i found the problem in my case. With Gemini and the Terminal i found out that the youtube websites were blocked from old software i had installed like surfshark VPN, Foqos App. Something must have happend when uninstalling. So i installed them again and uninstalled immediately afterwards. 

Gemini Prompt: There is a deeper underlying error in the macOS network stack. Because standard websites load while specific connections like YouTube don't, we will bypass the browser to check the packet size (MTU) and extract the exact encryption error. Please open the Terminal app, enter the command: curl -v (https://www.youtube.com), and share the generated text—especially the lines starting with an asterisk—so we can precisely determine where the SSL handshake fails. 

I would recommend to describe your problem to Gemini with this prombt and see what's the outcome.

Hope it helped somebody.

Have you tried creating a new user account and seeing if it works there? I have no issues with YouTube in Safari in macOS 27. That would cause me to consider that it's not a systemic bug but rather some issue caused by your configuration.

Do you use VPN by any chance?

If you do delete the VPN app and reboot.

As said YouTube is working fine with Sequoia 15.8 and Safari 27.

I contacted Netflix live chat as the problem occurs on Netflix and Youtube only. (I have no problem on Prime)

They say this issue is related to Apple and that Apple needs to develop a new update to fix the problem. (Apparently, Safari 27 or Sequoia 15.7–15.8.2 didn’t work well on the 2020 MacBook.) I don’t know if this helps… (No, not really, because there’s nothing I can do but wait—I’m not even sure if Apple is aware of the issue.😮‍💨)

And I agree this is NOT professional.

Use a different browser - anything but Chrome. I'm still on Sequoia but my list of sites which don't work properly with Safari but work OK on Firefox is growing every week.

Identical problem as me Sergio! I’m using Air 2020 i3 too.

I’ve found using the DuckDuckGo browser will play, so perhaps try that.

I find YouTube OFTEN opens with an Ad, rather than the selected content I expected.

if you have Ad Blockers active, you will likely see exactly nothing until the Ad finishes.

I am also running Sequoia 15.8 and YouTube works fine and it has nothing

to do with the latest Safari 27 version.

Try

1. Empty the Safari cache
2.  > Force Quit > Safari
3. With the Shift key pressed, restart Safari

I’ll erase all settings iCloud etc, reinstall macOS again, system back to previous safari from 27 to 15.8 or something, after that, YouTube back to life, I tried updating Safari again to 27 and the problem returned! So issues with safari 27💁 at MacBook Air 2020😉

After updating to MacOS 27, my Mac Mini M2 won't play YouTube or even Netflix properly. I am using 2 displays and the problem occurs to me when the main display is selected as my main audio output. However, when I choose the secondary display as my audio output, refresh the website, then it'll work properly. The reason why this won't work for me is because my secondary display is a tiny 7" monitor that I specifically use to keep my work chat open all the time. So you can just imagine the low audio quality.

And after researching, it looks like this issue has been reported even before the official global release of MacOS 27 so it's surprising to see that Apple ignored the bug reported and allowed the roll out.

Funny how we have to come up with workarounds instead of Apple "engineers" just doing their jobs properly and fix the simple bugs before the official roll out of what they proudly present as their best ever yet OS.

Hi again everyone...

I had a loooooooong chat with ChatGPT today.

We tried a lot of things together. I restarted the computer countless times, shut it down, tried different settings, and so on.

In the end, I even took screenshots of our conversation here and sent them to ChatGPT.

The conclusion is :

The findings suggest that there is likely a video playback incompatibility between Safari 27 and certain Intel MacBook Air models. The exact technical cause is not yet known. Therefore, I no longer recommend that you reset the computer, reinstall macOS, or change the same settings again.

I think there’s one more thing worth investigating: whether the video processing change in Safari 27 that’s causing this issue can be safely disabled using one of Safari’s experimental features. However, we shouldn’t randomly change an unverified setting.

For now, the most sensible approach is to treat this Safari bug as a separate issue until a solution is found that users experiencing the same problem have confirmed actually works. Thanks to the screenshots you sent, we now have a much clearer understanding of the scope of the problem.

😭😭😭

Try to use the internal speaker.

Do not output the sound via the HDMI/thunderbolt

Apple will probably send out a patch sooner or later. Till then we'll just have to use Youtube on another browser.

I even took the machine to an Apple Store, they could not make any impression on the issue, except that they recommended that I either reset to Factory settings, which would only replicate the problem, or use Firefox until Apple issue a fix. Wonderful! In the meantime the laptop is a complete PITA.

I can confirm YouTube plays fine in DuckDuckGo.

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.

For those that haven't already done so, I encourage you to submit feedback to Apple. Hopefully the more people who submit feedback, the quicker it'll get fixed.

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.

I have the same problem. I reset my machine to factory settings and YouTube started working just fine. Then Apple pushed a Safari update. After installing that update, it stopped working again. Good times.

Thank you, but unfortunately this hasn't resolved the issue.

I used the laptop to watch YouTube just about every day, but once I updated to 15.8 and Safari 27, it won't work.

Thank you. I was only using internal speaker. No HDMI/thunderbolt.

Same and done all the "try this try that" and still nothing fixes YouTube after the Safari update. Watching my YouTube on Firefox. What a hassle ugh...

Same problem, nothing fixed that, can apple do something bout it?

yeah I have this problem too I have a same MacBook Air intel i3 2020 That so badd at first I think updating it it will make everything more smooth but not it doesn't work with YouTube hahahaha

Same here, today I updated to Safari 27.0, and now YouTube won't work.

I'm using MacOS 15.8 on MacBook Air 2020

The issue is still occurring, are there any updates?

I don’t get any options if click and hold on the refresh arrow. But I did right click on the URL to show the privacy settings for the website. I reduced privacy restrictions, but still no luck.

I suggest providing feedback to Apple. Hopefully that will speed up the fix, although I’m not holding my breath.

MacBook Air 2020更新MacOS 15.8之後,Safari不能瀏覽YouTube網頁。

same here. MacBook Air 2020, Safari 27, Mac OS 15.8, can't play any online video by Safari.

Tried without success :-(

Same here, all videos (Netflix, etc) will not work on Safari on my Macbook Air 2020

Same here .. Intel Macbook Air 2020. So frustrating

I have gone back to using Chrome, but I'd rather not. I contacted Apple, but of course their response is to do nothing.

I have the same problem (and I hate Chrome because of this). Apple offered nothing. (I hate Apple because of all of this and MacBook Air 2020!) 😭

Please notify Apple here..

I have contacted Apple twice. No response.

If anybody updated to Sequoia 15.8.2 and the latest Safari Version 27.2 (20625.2.8.18.4), I'd be interested to hear if it fixed anything. It wasn't helpful for me 😔

I have a 2020 MacBook Air i3. I updated it to 15.8.2 and Safari to 27.2, but nothing changed. Videos still don't work, and it's been like this for almost 2 months now.

Still happening on 15.8.3, with Safari 27.2 (20625.2.8.18.4).

Intel MacBook Air 2020 w/ 1.1GHz Core i3, fresh re-install (no app, no Adblock, no login, no history).
