How can I remove the window shadow in El Capitan?
1. I tried ShadowKiller and ShadowSweeper, they do not work anymore on El Capitan.
2. I tried to disable System Integrity Protection, but it does not work.
3. toggle-osx-shadows also does not work: https://github.com/puffnfresh/toggle-osx-shadows/issues/17
Does anyone have other way?
Thank you!
iMac, OS X El Capitan (10.11)
