Command N not working

Create keyboard shortcuts for apps on Mac - Apple Support

If you are quite used to the shortcuts, you may be able to create your own using the link above. As said by dialabrain, this is how Sonoma behaves.

Try booting into Safe Mode and see what the "New Finder Window" displays as the shortcut. If it now shows "Command N", you have something installed causing the problem.

Thanks for your answers!

As I tried to explain. The shortcut has been changed in Sonoma.

I tried to create the shortcut myself using the help in the link but it didn't work.

I will share a couple of screenshots of System Settings and the dropdown menu afterwards: as you can see, no shortcut is shown in the dropdown menu.

That's because you tried to override the default shortcut.

You're welcome.

However, I was mistaken. The keyboard shortcut has not changed. I checked Sonoma on my iMac Pro and M1 MacBook Air. It's still "Command N" while in the Finder. I doubt it's because of the M2 but I don't have one to check.

In order to open a new window, I now must hit Option + Command + N.

Correct. That's how Sonoma behaves. It's normal.
