If a server certificate is signed by a CA that is not trusted by computers that run Horizon Client for Mac, you can configure these computers to trust the root and intermediate certificates. You must distribute the root certificate and all intermediate certificates in the trust chain to the client computers.


  1. Deliver the root certificate and intermediate certificates to the computer that is running Horizon Client for Mac.
  2. Open the root certificate on the Mac computer.
    The certificate displays the following message: Do you want your computer to trust certificates signed by CA name from now on?
  3. Click Always Trust
  4. Type the user password.
  5. Repeat steps 2 through 4 for all intermediate certificates in the trust chain.
