macOS - SonicWALL Certificate Installation

Open the Certificate

Double-click the downloaded SonicWallCertNew.cer file. This will open the Keychain Access application.

Add to Keychain

A dialog will appear asking which keychain to add the certificate to:

Select "System" keychain (recommended for all users)
Or select "login" keychain (for current user only)
Click "Add"

Enter Administrator Password

You will be prompted to enter your macOS administrator password to complete the installation. Enter your password and click "Update Settings" or "Modify Keychain".

Trust the Certificate

Open Keychain Access (if it's not already open):

Go to Applications → Utilities → Keychain Access
Select the "System" or "login" keychain (where you installed the certificate)
Find the SonicWALL certificate in the list
Double-click the certificate to open its details

Set Trust Settings

In the certificate details window:

Expand the "Trust" section
Change "When using this certificate" to "Always Trust"
Close the window
Enter your administrator password when prompted

Important: You must set the certificate to "Always Trust" for it to work properly. Without this step, you will continue to see certificate warnings.

Restart Your Browser

Close and restart your web browser (Safari, Chrome, Firefox, etc.) for the changes to take effect.

✓ Installation Complete!

You should now be able to access DPI-SSL protected sites without certificate warnings.
