How to Fix Aura Anti-Virus and OnyX Not Working in macOS Tahoe 26.2

With the release of macOS Tahoe 26.2, many users have found that third-party security and maintenance tools like Aura Anti-Virus and OnyX have stopped working. This is usually due to Tahoe's tightened System Integrity Protection (SIP) and changes to Full Disk Access permissions.

Recommended Troubleshooting Tool

Before proceeding with manual fixes, we recommend using CleanMyMac X. Quickly identify high CPU apps and optimize system memory with one click.

Method 1: Reset Full Disk Access

Even if the app shows as "Authorized" in settings, the permission database in 26.2 can become desynced.

  1. Go to System Settings > Privacy & Security > Full Disk Access.
  2. Select Aura or OnyX and use the minus (-) button to remove them.
  3. Click the plus (+) button and re-add the apps from your Applications folder.
  4. Toggle them ON.

Method 2: Check for Version Compatibility

Tahoe 26.2 introduced significant kernel-level changes.

- OnyX: Ensure you have the version specifically built for macOS 26. Using a Sequoia or older version will result in a crash.

- Aura: Check the Aura website for the "Tahoe Compatibility Update."

Method 3: Reset App Permissions via Terminal

If the UI toggle doesn't work, you can force a reset of the privacy database.

  1. Open Terminal.
  2. Run the following command to reset all privacy permissions for a specific app (replace "OnyX" with the app name):
tccutil reset All com.titanium.OnyX
  1. Relaunch the app and grant permissions when prompted.

Method 4: Clear System Caches

If the apps crash on launch, corrupted system caches might be the cause.

  1. Restart your Mac in Safe Mode (Hold Shift on Intel, or hold Power then select Options > Shift on Apple Silicon).
  2. Wait for the login screen, then restart normally. Safe Mode clears font, kernel, and system caches.
