macOS 顶栏的透明度如何更改呢？

[wuling]

有这方面的配置文件或者软件吗？

感觉有些壁纸，调低顶栏透明度后整体会更漂亮点

[Lonely]

隐藏掉

铜球，没透明度我快死了

Yosemite 可以用 Flavours 2.
El Capitan 目前还不可以。
Apple introduced a new security policy on OS X El Capitan, preventing every process (even privileged ones) from modifying system files, either on filesystem or dynamically at runtime. Unfortunately, with these security restrictions in place, this is the end of line for Flavours. - See more at: http://flavours.interacto.net/#0
