Disable window shadow on 10.11 / 10.12?
Solution 1:
edit 01-11-2019: Works on Mojave.
There is a solution - plugin called winBuddy which is available through MacForge (previously known as mySIMBL).
It allows you to turn off window shadow and/or window borders for every app.
I've just tested it and it seems to work properly, there are some minor glitches here and there but nothing major.
Minor glitches include:
- You can't change window options for apps which don't have menu - like Bartender for example
- You can't change window options for some apps, as winBuddy does not show up under 'Window' in menu.
