IrukaDark ships a helper binary named IrukaAutomation that uses the macOS Accessibility API. macOS manages permissions per binary; after an update replaces the binary and its code-signing hash changes, the previous permission can be invalidated and an Accessibility error may appear.
Fix 1 (recommended): Re-add in Settings
/Applications/IrukaDark.app.Fix 2: Reset via Terminal
tccutil reset Accessibility com.core.irukadark
# Restart the app and allow the permission dialog when prompted
Fix 3: Full reset (if the above fails)
sudo tccutil reset Accessibility
Note: This is due to macOS security behavior; even signed apps can be affected when binaries are updated.
No, it does not work during sleep mode. For the schedule feature to work, your Mac must be awake and IrukaDark must be running. To automatically open apps or websites at a specified time, make sure your Mac is not in sleep mode at that time.
