Safari 14 Dev Preview shows the userAgent string as "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_16)". It should say MacOS 11.
*** Bug 219728 has been marked as a duplicate of this bug. ***
Not even that!
Safari shows this user agent:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0.3 Safari/605.1.15
Also on Silicon Macs it still shows "Intel"
Please fix this urgent bug because a lot of websites are broken because of that!
I Hope this bug will be fixed this year

This aspect is intentional.

What are the websites that are broken because of 10_15_6? We are aware of websites that would be broken but exposing version 11, but not vice versa.
That is really sad because this intentional step break the sense of the user agent more than just using the user agent regularly.
A lot of websites checking the user agent if the browser supports vp9.(or other system relative features)
On IOS it works perfect (on iOS 13 you get the message with the to old system)
But on Safari on macOS the app still detects an incompatible System version.
Hh but wait I use the desktop user agent as a default on my iOS device does that mean that this confuses a lot of websites?
Yep a lot of websites still tell me incompatibility because of that.
Google Chrome as example use the user agent as intending and there are no problems at all.
If The User agent is 10_16 I can totally understand that but 10_15_6 is completely unreasonable and make the development much harder.
This is the perfect proof that the user agent is the biggest bulls*** and I hope that chrome gets through with there new User Hint System! (and Safari too)
So if you don't use the user agent as intended please at least change it to 10_16 so that developers doesn't feel fooled and need to rewrite a lot of things (which a lot of developers just doesn't do)
I recommend reaching out to webkit-help to discuss how to detect VP9 support. There may be a better way than checking OS version.
Max G, some websites are breaking because of macOS 11 string. So it's a two edges sword.
Would you be kind to share which websites are breaking that would be super helpful to assess the Web compatibility issue surface?
Note that you can check some of the followup issues
Blink (Chrome, Edge)
As Alexey said, reporting "Intel" as a constant is deliberate, and the 10_15_7 cap was done to mitigate web content breakage (see Bug 216593), and has been followed by Firefox and Chrome at this point.
It seems unlikely we will increase the passive fingerprinting ability to go back to reporting the real version number at any point in the future.
