  <p>The public and private key pair are visible in my keychain. However, when I am double clicking on the xx.p12 file downloaded in my system, I am asked for the password, where I tried both my system password as well as private key password but still I am getting this issue: An error has occurred. Unable to import an item. The contents of this item cannot be retrieved.</p>
  
  <p>What am I missing here? I have xx.certSigningRequest as well in my system.  I am not sure if I have to double click to install the xx.p12 file and run my app to enable push. What should be the problem here?</p>
