Why the app needs certain permissions
Chronixo is a time tracker. To capture screenshots, detect active apps, and know when you are idle, it needs access to protected system features. Here is exactly what it needs and why.
BYOS S3:If your admin has configured Bring Your Own S3, all screenshots write directly to your company's AWS, GCP, or Azure bucket and never touch Chronixo servers.
macOS is the most restrictive. Gatekeeper, Screen Recording, and Accessibility all require manual approval. You will see security warnings - this is normal behaviour for apps installed outside the App Store. Follow all steps in order.
Click the macOS download button above. Open the .dmg file. Drag the Chronixo icon into your Applications folder. Do not run it directly from the .dmg.
The first time you open Chronixo, macOS may say "Chronixo cannot be opened because the developer cannot be verified." This is Gatekeeper blocking apps not from the App Store.
Method 2:System Settings → Privacy & Security → scroll to the Security section → click "Open Anyway" next to the Chronixo warning.
If you see "Chronixo is damaged and cannot be opened", run this in Terminal: xattr -cr /Applications/Chronixo.app
Without this permission, all screenshots will be blank or fail silently. macOS blocks all screen capture by default until you explicitly allow it.
Apple menu → System Settings → Privacy & Security → Screen Recording → find Chronixo → toggle ON → Chronixo will restart automatically.
macOS 11 & 12 (Big Sur / Monterey):
Apple menu → System Preferences → Security & Privacy → Privacy tab → Screen Recording → check the box next to Chronixo.
Allows Chronixo to detect which application is in focus and read browser tab URLs to generate the activity accuracy percentage.
macOS 11 & 12:System Preferences → Security & Privacy → Privacy → Accessibility → add Chronixo.
So the tracker is always running when you start your Mac.
macOS 11 & 12:System Preferences → Users & Groups → Login Items → click + → select Chronixo.
Open Chronixo from Applications or menu bar. Log in with your Chronixo account. Pick a task and click Start. The app sits in your Mac menu bar while the timer runs.
xattr -cr /Applications/Chronixo.app - then try opening again.All permissions at a glance
