macOS says Turbo cannot be opened — what to do?

This is common and does not mean the installer is corrupted. macOS checks developer signatures and notarization for newly downloaded apps. If Turbo hasn't built local trust yet, the system may block launch.

Use either method below to open Turbo Browser normally.

  1. Double-click the .dmg and drag Turbo to Applications (if not installed yet).
  2. If you see "cannot verify developer" or "from an unidentified developer" on first launch, don't repeatedly click "Move to Trash".
  3. Open System Settings → Privacy & Security.
  4. At the bottom, find the message about Turbo being blocked and click "Open Anyway" or "Open".
  5. Launch Turbo again from Launchpad or Applications.

TIP

On macOS Ventura and later: System Settings → Privacy & Security. Older macOS: System Preferences → Security & Privacy.

Method 2: Remove quarantine via Terminal

If Method 1 doesn't work, or you see "app is damaged", run this in Terminal (adjust the path if needed):

Terminal
$ xattr -d com.apple.quarantine /Applications/Turbo.app

This removes the com.apple.quarantine flag from the download so Turbo can launch.

Still won't start after install?

Check the following:

CheckNotes
Install locationConfirm Turbo.app is in /Applications/, not still inside the .dmg
macOS versionmacOS 11 or later recommended — see Download & install
ArchitectureChoose the package for your chip (Apple Silicon / Intel — see release page)
Re-downloadGet the latest package from Download & install and try again

Screenshot permissions on first use

macOS may ask for Screen Recording or Accessibility permission the first time you use screenshots — allow in System Settings as prompted. See Screenshots guide.

FAQ

"Turbo is damaged and can't be opened"?

Usually caused by the quarantine flag. Try the Terminal command above or re-download the installer.

Do I have to use Terminal?

No. Most users fix this with System Settings → Open Anyway; Terminal helps when that button isn't visible.

Is this safe?

Always download from the official tbrowser.cn download page. Removing quarantine only applies to files you downloaded from the official site.
