FAQ

Keychron V3 Max vs Yunzii C75: your questions

The Keychron V3 Max supports open-source QMK and VIA firmware, which allows for extensive key remapping, macro creation, and layer programming directly in a browser-based app. The Yunzii C75 uses proprietary software for customization, which may offer less flexibility than the community-driven QMK ecosystem.

Yes, according to its listed features, the Yunzii C75 supports macOS systems. The Keychron V3 Max also supports macOS and includes dedicated Mac keycaps and a system toggle switch for easy switching between Mac and Windows layouts.

The Keychron V3 Max is more suited for modding. It is available as a barebones kit, uses screw-in PCB stabilizers that support third-party replacements, and has open-source QMK firmware. The Yunzii C75 is hot-swappable but lacks the same level of firmware and stabilizer customization options.
