How to Enable Secure Boot on iMac Pro

Step #1. First off, make sure your iMac is turned off. Then, restart the computer.

Step #2. Now, you have to press and hold Command (⌘)+R right after you see Apple logo to start up from macOS Recovery.

When macOS Utilities window appears, click on Utilities → Startup Security Utility from the menu bar.

If you are asked to authenticate, click Enter macOS Password and select an administrator account and enter its password.

Next up, you have three options to choose from: Full Security, Medium Security, and No Security.

What’s Full Security and How Does It Work?

Full Security is the default Secure Boot option which provides the maximum level of security. Moreover, it offers the level of security that was previously available only on iOS devices.

When you start your Mac, it will verify the integrity of the operating system (OS) on your startup disk to ensure it’s legitimate. In case the OS can’t be verified, your computer will automatically connect to Apple to download the updated integrity information to verify the OS.

If the OS is not able to pass verification, you will receive an alert informing that a software update is needed to use this startup disk. Then, you need to click Update to open the macOS installer and use it to reinstall macOS on the startup disk.

Alternately, you can click Startup Disk and select a different startup disk. Your computer will attempt to verify it as well.

If you are using Windows, you will see an alert saying that you need to install windows with Boot Camp Assistant. If your computer fails to connect to the Internet, you will get an alert that an Internet connection is required.

Click on the Wi-Fi status menu in the menu bar and select a preferred Internet connection. Alternately, click on Startup Disk and select a different startup disk.

Besides, you have the option to use Startup Security Utility to lower the security level to Medium Security.

What’s Medium Security and How Does It Work?

If Medium Security is turned on, your computer will verify the OS on your startup disk ensuring that it has been properly signed by Apple (macOS) or Microsoft (Windows).

As it doesn’t require an Internet connection or updated integrity information from Apple, it won’t prevent your Mac from using an OS that isn’t trusted by Apple.

In case the OS fails to pass verification, macOS will send you an alert informing that a software update is needed to use this startup disk. You need to click on Update to open the macOS installer and reinstall macOS on the startup disk.

Keep in mind it will require an Internet connection. Alternately, you can click Startup Disk and select a different startup disk. If you are using Windows, you will get an alert saying that you need to install windows with Boot Camp Assistant.

What about “No Security?”

“No Security” doesn’t include any of the above security requirements for your startup disk. Hence, it’s not advisable to use.

That’s it!
