When you download and run apps on Mac OS from not identified developers it's required to trust them by Gatekeeper. Codesign terminal tool allows you to manually sign any app on your MacBook. Using this technique you can for e.g. sign Adobe Zii app. Apple recently revoked TNT’s certificate.

Open apps from anywhere in Gatekeeper

Usually when you will try to run an app downloaded from a different source then AppStore, the system will disallow you to open the application. The one solution is to enable the ability to open apps from anywhere in Gatekeeper using a terminal command. Launch Terminal and enter the code below.

Click enter and type the administrator password to execute the command. Open the crashed app and if it's not running navigate to System Preferences→ Security & Privacy → Allow apps downloaded from and select Anywhere or allow to open the specific app that will show in the selection menu.

Add an app to quarantine on MacOS Catalina

If it does not work on Catalina and app is flagged as “damaged” even with Gatekeeper disabled (sudo spctl –master-disable) use this command.

When you launch an app and it will quit unexpectedly on Mac OS a problem report window will display problem details and system configuration. If you find in the report the message 'Termination Reason: Namespace CODESIGNING, Code 0x1' it means that the app certificate was revoked.

There is a quick solution to sign any .app on macOS installing free codesign tool. Open Terminal App and execute the code to start the download and installation process of Xcode and the command line developer tools from the AppStore. Launch Xcode at least once to agree to the license.

Download macOS

How To Use Terminal On Mac

Find the appropriate download link in the upgrade instructions for each macOS version:

macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.

OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

Terminal Emulator For Mac

1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
   Catalina:*
   Mojave:*
   
   High Sierra:*
   El Capitan:
   
4. Press Return after typing the command.
5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument, similar to the way this argument is used in the command for El Capitan.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

1. Plug the bootable installer into a compatible Mac.
2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
   Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
3. Choose your language, if prompted.
4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
