I am the person who designed the PCB for the current prototype. It's running the open source ZMK firmware, and that one works flawlessly on Linux. I had a prototype connected to my notebook (T450s, Intel AC9260 wifi chip, Arch Linux) already and did not encounter any issues, and since it's open source and all configs are public, adapting the keymap to your needs and maybe get rid of some mac-specific things wouldn't be a problem.

In fact we are considering a software toggle (e.g. FN + ESC or maybe more complicated to avoid accidentally toggling it) that has a "Win/Linux" and "macOS" mode, but I didn't get around testing that yet.
