That's not a Mac layout. Function key is in the wrong place (it should replace the Insert key) and it's missing an Eject key.
I don't know why people find it so hard to believe when I say that there are no mechanical keyboards with a Mac layout. There just simply aren't. The best is the Matias Tactile Pro and even that has slight shortcomings (short Option and Eject button replaces F19). Pretty much everything else is just the manufacturer's generic PC keyboard with Mac-specific keycaps.
This one is exactly that: a generic mechanical keyboard with Mac-specific keycaps. Just look at the non-Mac variant: https://www.keyboardco.com/keyboard/uk-va109m-sakura-pbt-bac... It's exactly the same layout.
