Full-screen not working


  • Subject: Full-screen not working

I have one user of my macOS app (under macOS 13.4.1)
where the app does not want to go into full-screen mode.

It is a pretty plain app.

In the AppDelegate's method -applicationWillFinishLaunching,
I switch to full screen like this:

   [self.window toggleFullScreen: nil];

It works, of course, all the time on my Mac;
also, as far as I know, there is only one user where it does not work.

After toggleFullScreen, I could check if the window is in full-screen, but I
don't see I would gain anything from that.
The toggleFullScreen does not seem to provide any error value.

I have already googled, but it seems like what that user reports does not
happen anywhere else.

Is there anything that could prevent a window from going into fullscreen mode?

Best regards, Gabriel
