How can I enable dark theme of GUI? I can not believe that it is not possible. As I googled - theming was possible at the past but now for security reasons I need look to the bright screen at night.
Quote from flavours.interacto.net: 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.
No workaround?
