Thanks, Wolfgang. I find this surprising because my program is minimal (source 
code below). I wasn’t getting this before, will look for what has changed...

#import <AppKit/AppKit.h>

int main()
{
  NSApplication *app;
  app = [NSApplication sharedApplication];

  NSAlert * alert = [[NSAlert alloc] init];
  [alert setMessageText:@"Hello alert"];
  [alert addButtonWithTitle:@"All done"];
  int result = [alert runModal];
  if (result == NSAlertFirstButtonReturn) {
    NSLog(@"First button pressed");
  }
}
