Solved on Mac 10.15.2: freemind not showing window. Visible in the freemind menu. On macbook push up with 3 fingers (mission control) and look for small window (only red,yellow,green) - select the window and look for it in the same position. Enlarge with the pointer as normal enlarging/shrinking a window.

Did it solve the problem ? Where is the ~/.freemind/auto.properties on a Mac ?
