How to Install Software from Unsigned Developers on a Mac

Allowing All Software

1. Open Spotlight

   . Click the magnifying glass icon in the top-right corner of the screen. In order to allow all software installations, you'll first need to restore an installation option that MacOS Sierra got rid of.

2. Type in terminal, then click

   Terminal. It should appear directly below the Spotlight search bar.

3. Type sudo spctl --master-disable into Terminal and press ⏎ Return. This is the code that enables the installation option.

4. Enter your password. This is the password you use to sign into your Mac. Doing so will restore the option you need in the Security & Privacy menu.

5. Open the Apple menu

   . Click the Apple logo in the top-left corner of the screen. A drop-down menu will appear.

6. Click System Preferences. This option is near the top of the drop-down menu.

7. Click Security & Privacy. It's near the top of the System Preferences window.

8. Click the lock icon. It's in the bottom-left corner of the window.

9. Enter your password, then click Unlock. You should now be able to edit the settings in this menu.

10. Check the Anywhere box. It's below the "Allow apps downloaded from" heading near the bottom of the window. Doing so prompts a pop-up window.

11. Click Allow From Anywhere when prompted. Doing this will allow you to install software from unsigned developers without having to confirm from within this menu.

    1. If you don't install any unsigned software within 30 days, you'll have to re-enable this settings.
    2. Click the lock icon if you'd like to prevent further changes.

12. Install your software. You should now be able to install your software as you usually would.
