I get that, but look at how many different cameras are on that list, and each one, I mean each one, has a different RAW format! My Z5 is on the list and works. My Z8 has 3 different NEF formats, and one is supported! It's like if every car model had a different gasoline port, and a hose to fill the tank of a 2024 Corvette wouldn't fit a Ford Mustang, or even a 2025 Corvette!
But I see little point in editing RAW files in Photos. As I said earlier,I let my jpgs inform me which NEFs to edit in Lightroom. In any case, if you really want to load your compressed NEF files, you can use Adobe's free Digital Negative (DNG) converter to make a universally acceptable RAW picture file. This is the format that Lightroom uses when it creates a new (edited) RAW file, and Apple and Photos support it.
Maybe it's Nikon and Cannon that should come up with a single RAW format that can handle data from any of their cameras.
