 427 Mac Implementation note :
 428
 429 The Mac has only one global menubar, so we attempt to install the currently
 430 active menubar from a frame, we currently don't take into account mdi-frames
 431 which would ask for menu-merging
 432
 433 Secondly there is no mac api for changing a menubar that is not the current
 434 menubar, so we have to wait for preparing the actual menubar until the
 435 wxMenubar is to be used
 436
 437 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 438 auto-merge for MDI in case this will be necessary
