Q: Mac Pro dark screen and cursor at startup

My Mac Pro won't startup. It begins Startup but stalls on a black screen.  None of the fixes recommended work (I've tried them ALL). What I finally figured out is El Capitan doesn't like more than one monitor (I have three). When I unplug two monitors, it starts up fine. Yosemite worked fine with three screens, ElCapitan started fine if I unplugged one of the thee monitors. The latest version requires me to unplug two monitors so it can start up.

MacPro, Mac OS X (10.6)

    I have had a similar issue after upgrading to 10.11.3. My fix was to click around the center of my screen to select my user even though the screen was black and showed solely my cursor. I typed my password and hit enter.  Once you finally boot into the OS, enable Automatic Login and choose your user. Problem temporarily solved until Apple addresses the issue.

    Thanks, that solved my issue. I've tried so many things these past two months, I can't believe how simple the solution was
