2. Enter the password.
3. The certificate is now installed and can be used for network or secure web site client authentication.
4. If opening the PFX file does not open Keychain Access, search for "Keychain" in Spotlight and open it. After launching the Keychain Access, select File. Click Import Items.
   
5. Select the certificate you wish to import.
   
6. Enter the password and complete the process.
7. The certificate is now installed and can be used for network or secure website client authentication.
