Welcome to Geekhack!
You are spoilt for choice, really. Presumably you have a Mac - most mech keyboards work fine on a Mac, even if the key cap legends are not exactly the same.
I have a Ducky Shine (version 1) which I use on my Mac - works fine. I used a CoolerMaster QuickFire Rapid for a little while - worked fine.
Do you want backlighting? Numeric keypad? Particular layout (ANSI, ISO, Mac)?
