Uh, no. Maybe if you use that awful flavours program that hooks into the system graphics API and swizzles all of the changes, but I patch the system files themselves (ThemePark, [S]ArtFileTool, ThemeEngine, whatever AZielenski comes up with next). In fact, the GraphiteAppearance and SystemAppearance.car files are &#x2F;smaller&#x2F; than they were when I started. All you need to do is log out&#x2F;back in, restart, or simply kill and restart the program for the changes to take effect. You probably need to disable that incredibly stupid rootless `feature` on 10.11 though
