How to Regain Control Over App Installation on Your MacBook Pro Running 10.12.5

Are you frustrated with the lack of control over app installation on your MacBook Pro running macOS Sierra (10.12.5)? You're not alone. The introduction of Gatekeeper has made it more difficult for users to install apps from unknown sources, but there's a way to regain some control if you know where to look.

For most Mac users, it's recommended to stick with the default settings and only allow apps to be installed from the App Store or identified developers. However, advanced Mac users and developers may need more flexibility when it comes to installing apps.

To reveal the third option in Gatekeeper and regain control over app installation on your MacBook Pro running 10.12.5, you'll need to disable Gatekeeper from the command line. This will remove the standard security mechanisms built into Mac OS, so proceed with caution.

To do this, open the Terminal app on your MacBook Pro and enter the following command: `sudo spctl --master-enable`. You'll be prompted for your administrator password, so enter it carefully.

Once you've disabled Gatekeeper, you can go to the Security & Privacy preference panel and find the 'General' section. From here, you should see a new option labeled 'Allow applications downloaded from anywhere.' This option is hidden by default in Gatekeeper for macOS from Sierra onward, but disabling Gatekeeper will reveal it.

Keep in mind that this method is not recommended for most users, as it removes important security mechanisms built into Mac OS. However, advanced Mac users and developers who need more flexibility when it comes to installing apps may find this workaround useful.

Remember to exercise caution when installing apps from unknown sources, as they may pose a risk to your system's security. With great power comes great responsibility, so use this newfound control wisely!
