Sierra sharing desktop
I have a headless 2010 Mac Mini that I use as my home media server, and have found that now that I have set it up, I cannot share the desktop.
I have disconnected the Mac Mini & hooked it up to my TV with a bluetooth keyboard & mouse, and everything worked as expected, but when I restart without the TV & bluetooth keyboard/mouse, what happens is a problem.
I connect using my MacBook Pro, and the screen loads up, but a vertical strip of the right ¼ or so of the MacMini's desktop shows up at the left side of the screen. The remote screen will not accept mouse clicks, keyboard strokes, anything.
Can I re-install el capitan on that machine? That worked fine.
MacBook Pro, OS X El Capitan (10.11.3), Home Machine
