Native by Design: Like It’s Made by Apple

O2 doesn’t look like an accessory—it looks like part of your Mac. With its elegant transparency and refined matte finish, it echoes the aesthetic of Apple itself. The soft-rounded edges recall the Mac Pro, while the combination of aluminum, crystal-clear PC, and eco-friendly ABS reflects a deep understanding of Apple’s material legacy. From the iMac G3 to the Mac Pro, O2 doesn’t imitate—it evolves.

It feels familiar before you even touch it. Because it belongs.

Every key knows your Mac.

All function keys are 100% natively mapped—including brightness, volume, Mission Control, and media controls. There’s no setup, no software, no compromise.Press it. It works. Like oxygen: invisible, essential.
