Have you tried Full-screen mode (press F)?
By doing that, when being in Photoshop in the top bar, from View in the top menu I am getting zoom in, zoom out, fit on screen and actual pixels. All of them work on the image only and not on the total window, and F from the keyboard doesn't work. The interesting thing is that I got it, yes, a nice window with the bottom information sitting on top of the dock, and the tragic is that I can't replicate it, I just touched something in the top left area of the screen.
I can't post a screen shot of the succesful widow because I went back to View>fit on screen to verify if I got it from there, and I lost it.
All I can tell you is that I pressed something at the top left of the screen, but it's not the hand, because it doesn't work, so there is actually a better way then going crazy with the bottom right corner. Thank you anyway.
I hope at least it's getting more interesting!
So actually it was indeed command F from the keyboard, I just re did it, I'll be there with the star in a minute. Thanks for ending this nightmare!
