Hi, im korean.
I became interested in the beam spring keyboard, but it is unfortunate that there is a lack of interest and materials about the beam spring keyboard in Korea. I support your project
I’m a Mac user, but I don’t see a separate key option for Mac in Round 2.
There is no separate key option for Mac on the Beam Spring Round 2 Keyboard. How do I purchase the key option for Mac?
Please see the key set photos on the beam spring product page to see which keys are included: https://www.modelfkeyboards.com/product/beam-spring-keyboard/
The needed Mac Cmd key is included. One can use the Alt key for the Mac Opt/Alt key. The Mac Ctrl key is also fine as there is a Ctrl key included.
If you prefer Icon Mac keys you can always consider using other MX key sets with the new beam spring keyboards.
