Frequently Asked Questions

Does the YUNZII B75 PRO work with a Mac?

Yes, the keyboard is compatible with Windows and macOS. The programmable software for key remapping, macros, and custom RGB runs on Windows only, so configure profiles on a PC first.

Can I change the switches without soldering?

Yes. The B75 PRO uses full-key hot-swappable sockets on the PCB and accepts both 3-pin and 5-pin mechanical switches, so you can swap the pre-lubed linears for tactiles yourself.

How long does the battery last?

YUNZII lists a 4000mAh battery, which is large for a 75% board, but runtime depends on RGB brightness and whether you use Bluetooth or the 2.4GHz dongle. Check the product listing for the manufacturer's rated hours.

What does the knob actually do?

Rotating it adjusts system volume or cycles the RGB backlight effects. A long press switches the keyboard between gaming and office modes.

Is this keyboard quiet enough for an office?

It is built for a muted, creamy sound rather than a sharp click: gasket mount, five layers of padding, noise-cancellation design, and pre-lubed linear switches. Linears have no tactile click, but it is still a mechanical keyboard, not a silent one.
