O2, derived from the chemical formula for oxygen, symbolizes an invisible yet essential force that sustains life. Similarly, we envision O2 as the productivity oxygen for Mac users in the digital age.

Inspired by Apple’s iconic use of transparency in design, O2 is crafted to ensure deep compatibility and seamless connectivity across the Apple ecosystem, like a native app pre-installed in macOS. It delivers Mac users a light, fluid, and effortless experience - just like the air we breathe.
