为什么我从 10.15.7 升级到 12.6.2，但是浏览器的 UA 还是显示 10.15.7 呢？

> Mozilla's Firefox team and Apple's Safari team have encountered a long tail of broken web content when the user agent string reports "Mac OS X 11_0_0" - basically, any macOS major version greater than 10. Per http://crbug.com/1175225 , both browsers have capped the reported macOS version to 10_15_7 to both work around this, and also slightly increase user privacy.

有趣的冷知识；
跟 IE 一样，IE 判断高于 7 提示不兼容。

@mons 感谢解答。
也就是说官方为了提高用户隐私，故意这么弄的？

@wps353 是说测试发现 UA string 改 11 后一堆网页无法正常加载。略微提升隐私是副产品
