Mac OS Sierra
Blender 2.79
Mouse click no longer works with the CTRL, ALT or CMD buttons. I can't select, or rotate view, or right click since upgrading to 2.79.
Tried it two with different imacs, with both a mouse and a tablet. Same error.
Foe example ALT + CLICK doesn't work to select the second box on the attached file.
