I'm not running 10.11.6 but saw posts in a previous thread about graphics driver problems ("kernel: stalling for detach...") in El Capitan after the original Security Update 2016-003 which say the supplement is supposed to address that.
FYI on Nvidia Driver Updates: Users of Nvidia's web drivers should know that new OS X updates (versions or later build numbers after Security Updates) typically break any currently installed Nvidia web graphics driver. Update: On Jan. 25th, 2017 Nvidia posted Graphics Driver 346.03.15f06 for OS X 10.11.6 build 15G1217. (Build number with Security Update 2016-003 Supplemental installed.)
