 523 Mac Implementation note :
 524
 525 The Mac has only one global menubar, so we attempt to install the currently
 526 active menubar from a frame, we currently don't take into account mdi-frames
 527 which would ask for menu-merging
 528
 529 Secondly there is no mac api for changing a menubar that is not the current
 530 menubar, so we have to wait for preparing the actual menubar until the
 531 wxMenubar is to be used
 532
 533 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 534 auto-merge for MDI in case this will be necessary
