I have a simple SharePoint Web Application which have no issue or bug, until a client open it in Safari browser version 7.1 on Mac OS 10.9 Mavericks a month ago.
Since I don't have any Mac OS, then I tried to open the web via browser emulator in http://www.browserstack.com/ and found that the problem is only happen in Safari 7.1 and 8 (no matter what the device, MacOS, iPad, or iPhone6)
When we open it using Google Chrome, Firefox, IE any version, even Safari 6 or older, it looks okay.
But when we open it using Safari 7.1 or later, the menu bar looks like wrecked.
Is anyone know how to fix it?
