Working in photoshop, pressing alt while moving removes layers (mac os) what's the problem?

Question

macOS

Working in photoshop, pressing alt while moving (or something like that, I don’t understand) removes layers (this is only in mac os) what is the problem?

Answer 1

Perhaps just Windows combinations in MacOS do not work, or do they work differently? Not?

Answer 2

You are not doing something. With the "Black Insole" tool active, the V shortcut - moving the selected layer with the viola pressed, copies the layer and moves its copy. How do you manage to delete a layer? I don't understand, please describe the error process
