Starting from application icon in finder. I didn't see X11 launch, so I launched it and then Inkscape and this is the console log: 20/12/09 7:34:52 PM [0x0-0xf20f2].org.x.X11[4425] Waiting for startup parameters via Mach IPC. 20/12/09 7:34:52 PM [0x0-0xf20f2].org.x.X11[4425] X11.app: Could not connect to server (DISPLAY is not set).
