Finding a good Mac-layout mechanical keyboard that I liked was a total chore, I eventually got the Vinpok Taptek which I'm really pleased with but I can't find replacement keycaps for the life of me.
It was good for about a year. Then i started having connectivity problems. The Letter in the keys wrote off quickly. And a few of the keys started becoming less responsive. The quality just wasn't there.
Luckily, by then Apple came out with its version, and it's been flawless for a few years now. It's worth the extra money to go with Apple, if you're getting that kind of keyboard.
There are many many many many mechanical keyboard options to use with a Mac. If you're legitimately having difficulty finding a solution, feel free to reach out to me via the contact information in my profile and I'll be happy to make some specific recommendations.
