Mac Photoshop isn't Transparent Anymore

[Patricia0709]

So I got my Photoshop on Mac last year and somehow, I think I accidentally pressed something. I used to have a transparent background whenever I use it so I can see the desktop but now it's all gray and boring. How do I turn it back? I have the Translucent option checked btw. Thanks for any help that will come.
