Sep 30, 2016

You can download the latest release from the Citrix Receiver for Mac download page.

What's new in 12.2

Generic USB redirection

This release supports generic USB redirection. It allows redirection of arbitrary USB devices from client machines to XenDesktop virtual desktops. With this feature, end users have the ability to interact with a wide selection of generic USB devices in their active XenDesktop session as if the device was physically plugged into it.

Generic USB redirection works at a low level, redirecting USB requests and responses between the client machine and the XenDesktop virtual desktop. It avoids the requirement for compatible device drivers on the client machine; the driver must be supported on the virtual desktop only.

Generic USB redirection can be controlled and configured by DDC policy. Use the Citrix Receiver menu bar and Preferences screen to control settings for USB devices.

Session reliability and auto client reconnect enhancements

This release of Citrix Receiver for Mac provides improvements in the area of session reliability and automatic client reconnection.

Users are notified when being disconnected/reconnected to a session.

Support improvements

  • always-on logging. This release introduces improved always-on logging, which helps collect important one-time event.
  • improved diagnostic gathering during session crashes. This feature is enabled by default, and can be disabled in the Preferences screen.

Security enhancements

Numerous security enhancements and improvements are included with this release of Citrix Receiver for Mac, including:

  • improved security configuration user interface. In previous releases, the command line was the preferred method to make security-related changes; configuration settings related to session security are now simple and accessible from the UI, which improves the user experience while creating a seamless method for the adoption of security-related preferences.
  • native OS X API support for smartcard authentication to NetScaler. This improves the usability of Native OS X API for smartcard authentication over NetScaler. Prior to this release, users were required to install the PKCS#11 module on the client machine to use smartcard authentication to NetScaler. Starting with this release, installing PKCS#11 is not mandatory.
  • TLS connections. Citrix Receiver for Mac allows you to verify connections made to servers that are using a specific TLS version, with additional information including the encryption algorithm used for the connection, mode, key size and whether SecureICA is enabled. In addition, you can view the server certificate for TLS connections.
