Keychron K3 Bluetooth Mechanical Keyboard REVIEW | MacSources

Awesome keyboard experience for macOS users.

For many years now, I’ve been searching for a mechanical keyboard that was designed to work with macOS. There are many different styles of keyboards that will work with macOS, but they aren’t designed for it. That means there are Windows keys on the keyboard instead of Command keys and in order to use the keyboard, you have to think about the CTL key being the alternative keystroke for commands. Is it possible for an Apple user to make use of a Windows mechanical keyboard? Sure, but it’s not preferable. That’s why I’m really glad I found Keychron keyboards and their K3 Bluetooth Mechanical Keyboard. I’ve used a different model in the past, but I really liked the idea of being able to customize my experience by swapping switches out. So, I gave it a try.


The Keychron K3 Bluetooth Mechanical Keyboard is an ultra-slim wireless keyboard with the world’s first hot-swappable low-profile Optical switches. The keyboard connects via Bluetooth or through USB-C. The keyboard features Bluetooth 5.1 and can work with computers, smartphones, tablets, or any Bluetooth-enabled device. The K3’s switches are 40% slimmer than conventional switches and it sits on a streamlined aluminum body. Since it’s designed for productivity and compact spaces, the keyboard features a 75% layout and does not include the 10-key number pad. It does still include multimedia and function keys. The RGB version of the keyboard has 18 different colored lighting effects that can be controlled by the light effect key on the keyboard. After 10 minutes of inactivity, the keyboard will go to sleep. You can disable the auto-sleep mode with a key combination on the keyboard.
