Installing
Three steps, about a minute.
- Unzip the download.
- Drag Cortex into your Applications folder.
- Open it. Cortex lives in your menu bar and starts remembering from your next session.
Cortex is notarized by Apple. If macOS asks on first launch, right-click the app and choose Open — that confirms you meant to open it, and you won't be asked again.
How updates work
Cortex updates itself automatically (via Sparkle) and tells you when a new build is ready — no need to come back here. You can also check manually any time in Settings → About → Check for Updates, where the release notes live. More on updates →
