There are many reports of 27 not playing videos. Report it. The more reports Apple gets the more likely they are to look at it.

Product Feedback - Apple

for me its the same. I run on the previous version of Safari and no problem. also reinstalled Sequoia 15.8.1 , problem back. again reinstall but no update Safari 27 and no problem

I chatted with Support this morning. Did multiple troubleshooting steps/fixes, nothing worked. They talked me through recovery mode and reinstalling the OS and it worked. Safari working well now.

Safari 27.0, released on September 14, 2026, is the latest version of Safari for Sequoia. Previously, Safari 26.6, released on July 27, 2026, held that position.

I have the same problem since updating to Sequoia OS 15.8.1 (24H32) two days ago. (on my MacBook Air Retina 13-inch 2020, 1.1 GHz Dual-CoreIntel Core i3, Intel Iris Plus Graphics 1536 MB). Can't run any videos on Safari.

this sounds like an ad / spam?

A recommendation for Etrecheck is neither an ad nor spam. The software is free. It provides information that's designed to help with troubleshooting while not exposing any personal data. It saves a lot of time as people don't have to keep asking questions. You are certainly free to support the developer by buying the paid version but you don't need to.

I have reinstalled multiple times with loss of settings and documents and without , and okay it works good. ,till the update safari 27 appears and I installed it. again nothing. as long I not install the update no problem. what have they done with your Mac different. You chatted with apple support the whole time? it takes hours to reinstall. how did you do it

Support stopped the chat when I was beginning the download of the OS, let me finish it on my own. Gave me a case reference number. This morning I realize Safari is running fine because I'm back to version 18.6! The system is offering version 27 update and I won't install it. Will have to contact Apple again and follow up, but at least this version seems to work with new OS.

Okay thank you. And yes that’s the point. No problem with the old safari. But when you update safari 27 it’s a mess

strange apple seems not really to notice the problem. I know there are many people who have problems with it

You said that you haven't been able to access YouTube since updating Safari. I'm running Sequoia 15.7.4 and Safari 27.0, and have no trouble accessing YouTube.
