Launcher Crash on OS X 10.11.6 when opening Epic Games Launcher

ok, I did all the stuff above, and EpicGamesLauncher opens, but when I try to launch a game it crashes, and I get a report that says:

CrashReporter: initialized
application requires at least OS X version 10.12.0 (10.12), but is being run on 10.11.6 ( 10.11.6/15G22010), and so is exiting.

Anyone else get this?
thx
