If Crashes when opening

Apple removed TNT’s certificate, so the app will crash after July 12th. The current solution is to sign it yourself.

Run in Terminal

codesign --force --deep --sign - /Applications/name.app

Requisite: Xcode or the Apple Command Line Tools
To install, execute

xcode-select --install

in the terminal emulator of your choice, and the macOS GUI will give you the option to install Xcode (from the Mac App Store) or the CLTs. If you install Xcode, launch it at least once to complete the installation and agree to the license.


Alternatively, you can use CodeSigner to sign some apps.

Installation instructions:

• downloaded CodeSigner, then mount the DMG volume
• Copy CodeSigner.app from the mounted DMG volume into one of your applications paths; recommended: ~/Applications/Utilities/
• If you are using macOS Finder or a similar application with Services support as your main file manager, double-click the CodeSigner workflow: a window titled Quick Action Installer will appear asking you if you want to install it; click Install. You can assign a keyboard shortcut to the Quick Action in System Preferences > Keyboard > Shortcuts > Services > Files and Folders > CodeSigner
• If you also want the ability to manually run CodeSigner in a terminal emulator—example:

• codesigner /Applications/Parallels\ Desktop.app

• —copy the codesigner shell script into your $PATH, e.g. /usr/local/bin/
• On Mojave please allow CodeSigner to control System Events; this is necessary for GUI prompts to work via AppleScript
