Issue: I am not able to import a certificate

Cause: I do not have administrator access

Solution: You do not need administrator access to import a certificate. Just do the following:

  1. Open Keychain Access in Applications > Utilities > Keychain Access 
  2. Highlight the "login" keychain, NOT the "system" keychain at the lefthand keychain list
  3. Drag your .p12 to the "login" keychain. Type in the password you use to login to the server
