[BUG] Broken UI in macOS 10.11

[NghiaTranUIT]

🐶 Brief

NSButton.imageHugTitle is only available from OS 10.12, so it is 💥

👑 Criteria

• Fix it 😳

[NghiaTranUIT]

• Ctr+F to focus on Search Bar doesn't work in 10.11 and 10.13. For some reasons, the first responder is resign as soon as we focus.

The Cmd+Shift+F to focus on Search Bar is fixed in Proxyman 1.3.4.3
