Information
FAQ
Answers to common questions about IrukaDark
macOS. Download the installer directly from the Downloads page.
It explains text in context—beyond word‑for‑word translation—so you get intent, background, and plain‑language explanations instantly.

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
- Open System Settings → Privacy & Security → Accessibility.
- Select IrukaDark and remove it (−).
- Add it again (+) and choose
/Applications/IrukaDark.app. - Restart the 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.
