It works fine in windows while in mac when I launch the app the app window does not appear as expected but it appears as a small window on the top left corner.
The similar issue is appearing with the progress dialog which I am using it works fine in Windows but in mac(OS X) when the app is expanded like when app window size is maximum the progress dialog is also covering the whole display screen while I have given fixed size to scene window.
This is my progress bar code:-
public ProgressBar startProgressBar() {
primaryStage = new Stage();
ProgressBar pb = new ProgressBar(0);
//ProgressIndicator pi = new ProgressIndicator(0);
//pi.progressProperty().bind(pb.progressProperty());
HBox hb = new HBox();
hb.setSpacing(5);
hb.setAlignment(Pos.CENTER);
hb.getChildren().addAll(pb);
Scene scene = new Scene(hb, 300, 100);
primaryStage.setScene(scene);
primaryStage.setTitle("Downloading Build...");
primaryStage.show();
return pb;
}

I am able find the solution for the first issue that can be solved my fixing the minHight and minWidth of the anchor panel to some value in fxml file instead of infinity but I am still not able to find the solution for the second issue.
