By default, the button placed onto a form by Lazarus is 75 width by 25 height, which is not the standard for Mac Applications.

In order for buttons to appear oval, make the button height 22 maximum.

This can be done by setting the button height directly or through code.

CODE FOR A SINGLE BUTTON:

procedure TForm1.FormCreate(Sender: TObject);
begin
  Button1.Height := 22;
end;

CODE FOR ALL BUTTONS:

procedure TForm1.FormCreate(Sender: TObject);
var
  I: Integer;
begin
  for I := 0 to Form1.ControlCount - 1 do begin
    if (Form1.Controls[I].ClassType = TButton) then Form1.Controls[I].Height := 22;
  end;
end;
