SSL certificate installation

This network employs a technology called captive portal which allows the administrator(s) to restrict network access to trusted users. In order to prevent certificate security warnings when accessing this portal, the network's filtering unit must issue to your computer or mobile device a file called an SSL certificate.

This guide will help you install the SSL filtering certificate for Mac-based browsers which use the operating system's built-in Keychain facility — this includes Safari and Chrome.

Step 1

First, click the Download Certificate button below; this will download the certificate file to your computer.

Step 2

OS X Downloads icon

When the certificate finishes downloading, it will appear in your default downloads folder. Usually, this can be accessed via the Dock near the Trash icon, or, depending on your browser, it may appear in a dedicated downloads window. Locate the file and click to open it.

(Note: These images show the steps for Safari running on OS X 10.12; you may not see exactly the same thing if you are using another browser or a different version of OS X; however, the general process and wording should be the same.)

Step 3

OS X Keychain Access Add Certificates dialogue

Opening the file will launch or activate the Keychain Access application. You may be prompted to select a keychain to start with; if so, choose login and click Add. (Alternatively, if you have administrator access, you may wish to select the System keychain to install the certificate for all users of the machine.)

Step 4

OS X Keychain Access context menu

Locate the newly installed certificate in the main Keychain Access window and double-click it, or right-click it and choose Get Info.

Step 5

OS X certificate trust settings

In the window that appears, expand the Trust section and select Always Trust for the Secure Sockets Layer (SSL) setting, then close the window.

Step 6

OS X password prompt

You may be prompted to enter your OS X account password. Do so, then click Update Settings.

Step 7

OS X Keychain Access certificates

The main Keychain Access window will now show that the certificate uses custom trust settings. Quit Keychain Access.

Step 8

You're done! After exiting Keychain Access you may continue browsing browsing as usual; in most cases, you will not notice anything different after the certificate is installed.
