Citrix Receiver for Mac users with Citrix Receiver already installed when upgrading to macOS High Sierra are automatically granted approval to the Citrix kernel extension that was already present.
Citrix Receiver for Mac does not require any explicit approvals to enable USB redirection when installed on previous versions of macOS (10.12, 10.11. and 10.10).

For each Cisco Unified Client Services Framework (CSF) device that you add to the system, Cisco Unified Communications Manager creates a configuration (CNF.xml) file. The CNF file contains the device specifications for the associated user.

When users sign in to Cisco Jabber, Cisco Jabber Softphone for VDI starts the download of the associated CNF file to the thin client. To ensure the successful transfer of the file, open the relevant ports in all firewall applications to allow the thin client to access the ports. For more information about how to open ports, see the documentation for the firewall software.

Important

Download of the CNF.xml file follows the system setting for HTTP proxy. Ensure that the proxy does not route the HTTP request from the thin client outside of the corporate network.
