If you are not sure which layout (Windows or Mac) you have opted for, don't worry. Keychron keyboards work with BOTH Windows and Mac, the only differences are the set of keys. With each Keychron keyboard, we provide both Mac and Windows keycaps to all buyers. So you do not need to select any specific layout while purchasing.
The US layout, ISO layout and JIS layout are provided now, but we welcome your feedback and opinions on the different layouts here.
