The WMPAINT-Procedure / LMPAINT-Message don't sends a "PaintRect" in its 
Message on Mac, so the Rect, what VST should paint again is everytime 
Rect(0,0,0,0) -> Nothing is painted.

Thats why it add in procedure TBaseVirtualTree.Paint:
{$IFDEF Darwin}
    FUpdateRect := ClientRect;
{$ENDIF}

Now its painted at least also on Darwin :)
