Missing Root/Intermediate Certificate

This error message suggests that the Mac client device does not have the required root certificate/intermediate certificate to establish trust with the certificate authority who issued the Secure Gateway/NetScaler Gateway server certificate.

Complete the following steps to resolve this issue:

1. Open the Keychain Access in the Applications > Utilities folder:

2. Highlight the X509 Anchors Keychain in the menu (you might have to authenticate to do this).

3. Browse through the Certificate Authorities to find the company that has issued the certificate that is being used by the Secure Gateway/NetScaler Gateway – for this example, Thawte Premium Server CA:

4. Highlight the certificate and select File > Export from the menu bar:

5. The default File Format should be Certificate (.cer).
   Note: You might need to rename the certificate to a .CRT extension for the client to properly identify the certificate.

6. Save the certificate to the ApplicationsCitrix ICA Clientkeystorecacerts folder (create this folder if it does not exist):

What is Citrix Receiver?

Citrix Receiver is a client software that is used to remotely connect to Virtual Desktop applications. It is available for most any platform but these instructions are for Windows or Mac OS.

Click the appropriate platform if you are on a mobile device: iOS, or Android.

Features of the Citrix Receiver

The user experience when connected to a Virtual Desktop application is designed to be as similar as possible to using an application that is installed on your local computer. Among the local resources you will have access to in the remote session are:

• Your Home Drive (H:): The H: drive that is mapped when you log into any computer on campus will be accessible from Virtual Desktop. In fact, when opening or saving a document in a Virtual Desktop application, your Documents, Desktop and other Windows profile folders are stored in your Home Drive or your H: drive.
• Local drives. These include hard disk drives, thumb drives and most USB devices that are physically attached to your local computer. They typically appear in the remote session as 'Local Disk (C: on {computername}' where {computername} is the name of your local computer. For example, if you have a document saved on the hard drive of your computer, which is called 'MyLaptop', you can open it in a Virtual Desktop application by clicking File | Open and browsing to 'Local Disk (C: on MyLaptop)'.
• Network drives. Any network drives (other than your H: drive) that you get when you log into Windows when you're on campus will show up in Virtual Desktop sessions. Citrix Receiver also recreates any other manually-created network drive mappings that are connected on your client computer when you log in.
• Audio. Sound from the remote application will play on the speakers that are connected to the computer you are connecting from.
• Printers. Citrix Receiver automatically creates (redirects) printer objects for your local printers so you can print to your local printer from a remote Virtual Desktop application.

How Do I Install Citrix Receiver on Windows or Mac OS?

Citrix Receiver For Mac 10

_{Note: The Virtual Desktop website is designed to detect whether you have a current version of Citrix Receiver installed. It is also configured to launch applications directly when you click on an application icon (as opposed to having to download a file and then open the file to launch an application). Unfortunately, recent changes in support in Google Chrome and Mozilla Firefox have caused one or both of these features to stop functioning unless you are running the most current version of Citrix Receiver.}

Uninstall Citrix Receiver Mac Os

• If you experience any issues, especially with applications not launching automatically when you click an application icon, please upgrade to the newest version of Citrix Receiver by following the instructions below.

• If you get any errors during the installation, please uninstall any old versions of Citrix Receiver and try again.

1. To download the most current version of Citrix Receiver, browse to https://receiver.citrix.com. The webpage will automatically detect your platform and offer an appropriate download link for Citrix Receiver.
