Very small documents in photoshop

Hello! After a few years, I got my first Macbook pro and I have a problem with photoshop. I have Photoshop CC 2020 ver. and some of my friends use the same version but they don't have the problem. When I open/create a document, it looks super tiny meanwhile when I save it and open in any of my browers it looks perfectly ok. I mean, a 500px document looks like a 250px in my photoshop, so you can imagine when I have to do things to a 100px document... It's tiny.

I hope someone could help me. Thanks!
