Run locally

git clone https://github.com/simone98dm/tully.git
cd tully
open tully.xcodeproj

Then Product → Run in Xcode, or from the terminal:

xcodebuild -project tully.xcodeproj -scheme tully -configuration Debug build

The built app is at:

~/Library/Developer/Xcode/DerivedData/tully-*/Build/Products/Debug/tully.app

Open it and look for the target icon in the menu bar.

First launch: grant Accessibility permission when prompted (System Settings → Privacy & Security → Accessibility). Required for the Window Manager. The app will show a prompt if permission is missing.

Notes

• The app is unsigned and not sandboxed — Gatekeeper may block it on first open. Right-click → Open to bypass.
• Disk scanning runs on demand only (tap Refresh in the Disk tab). Not automatic at startup.
• Keyboard shortcuts are stored in UserDefaults and persist across restarts.
