Install and use
Open the DMG for your Mac. Apple silicon is for M-series Macs; Intel is for Intel Macs.
Open the downloaded DMG and drag o2 to your Applications folder, then launch it.
Search an app, calculate an expression, or type a workflow keyword and press Enter.
Trust and privacy
The first release is an unsigned preview and is not notarized. If macOS blocks a trusted download, use System Settings → Privacy & Security → Open Anyway. See Apple’s guidance. Never disable Gatekeeper.
o2 has no account or hosted backend. User-authored workflows can execute commands or open websites, so review workflows before running them.
