Macos – How to decrease the window shadow in Mac OS X


I've found the default 40px Mac OS X window shadow too big:

mac os x shadow

Is it possible to decrease it to, say, 4px?

Update: I can disable shadows entirely with defaults write disable-shadow -bool true, but I don't want to. I do want decrease them.

Only the frontmost window has this huge shadow, it's smaller for background windows. So you can try screenshotting non-focused windows (easy if you activate e.g. Mail and close all its windows, so no window has focus). However you would have to live with the deactivated, washed out look or manually merge both deactivated and active window screenshots.
