About Citrix Receiver for Mac 11.9.x

Dec 02, 2015

Citrix Receiver for Mac provides users with self-service access to resources published on XenApp or XenDesktop servers. Receiver combines ease of deployment and use, and offers quick, secure access to hosted applications and desktops.

Important

Citrix Receiver for Mac 11.9.x and prior versions are not supported on OS X El Capitan (10.11).  If you have upgraded your device to El Capitan, please upgrade Citrix Receiver to the most recent version.

To upgrade, go to the Citrix download pages: http://www.citrix.com/downloads/citrix-receiver.html.

What's new in 11.9.15

The following new features and enhancements are available in this release:

  • Support for Transport Layer Security (TLS). Receiver for Mac now supports TLS 1.1 and TLS 1.2 protocols, in addition to TLS 1.0. When enabled, TLS provides secure communication between the server and client.
Note: Receiver for Mac is now able to make SSL connections to servers that are configured to support only TLS 1.2 or TLS 1.1. Previously, if a server was configured to exclusively allow these connections authentication would fail.

Known issues for 11.9.15

The following known issues have been observed in this release.

  • Mounting a Receiver disk image from two different builds results in a situation where the Receiver installer fails to upgrade to the newer build image. [#546150]
  • Users with computers running Mac OS X 10.8 might see overlap on the string log on and down icon on the Receiver user interface. Users can click Log on or the user name string instead of the down icon if this occurs. [#504302]
  • Changing the viewer to full screen while the DirectX or OpenGL application is running might cause the cursor to disappear. [#510745]
  • When server language is set to traditional Chinese, users might not be able to input "[“ or “]" within a session. [#511877]
  • Moving the cursor does not change Lync status from Away to Available if the status change was due to the user being idle. Users must manually change the status to Available if this happens. [#512074]
  • Application names viewed on Receiver might not reflect updates on the Broker and StoreFront if the user subscribed to the apps before the updates occurred. Users can delete and resubscribe to the app if this occurs. [#515097]
  • In a multiple monitor configuration, seamless apps might move to the primary display when any display is reconfigured. [#506532]
  • HDX apps might turn black. If this happens, drag applications and close them by clicking where the close button should be located. [#426991]
  • In Mac OS X 10.10, the upgrade version of Safari might block Receiver as a pop-up window. Enabling pop-ups windows for Apps/Desktops to open will fix the issue.

Issues fixed in 11.9.15

The following issues have been resolved in this release of Receiver for Mac:

  • When using smart card authentication on Mac OS X 10.10 (Yosemite), the session with the VM initiated properly and the Windows login screen appeared, however, when you selected the displayed SmartCard for authentication, Receiver displayed a warning message indicating that "no certificate found." [#512847]
Note: To use smart cards on OS X 10.10, you must have a least OS X 10.10.2 installed.
  • In some cases, Receiver would crash when disconnecting from a session. [ #525553]
  • Security messages erroneously displayed when launching desktops from Receiver. [ #527411]
  • Start menu objects would blink when the mouse was hovered over them. [#527763]
  • Receiver reported network errors when adding a store with an IP address and not a FQDN.[#531732]
  • Receiver could crash when using the 'Copy as Picture' function in a Microsoft Excel published app. [#532051]
  • This release of Receiver for Mac resolves a security vulnerability with OpenSSL. [#534168]
  • In some cases, app activation may fail when simultaneous callback events occur between the server and the desktop.[#536077]
  • When a published Visual Basic (VB) app has multiple modal dialogs, clicking in a parent window could result in controls in that window disappearing. [#536540]

What's new in 11.9

The following new features and enhancements are available in this release:

  • Multiple monitor improvements. Users can now set Receiver for Mac to work in full-screen mode across multiple monitors through a new menu option Use All Displays in Full Screen.
  • Desktop Composition Redirection (DCR). DCR redirects DirectX graphics commands for Windows desktop composition to the user device. This feature improves XenApp and XenDesktop scalability and thereby reduces cost per user
  • Mandatory app. Administrators can make apps or desktops available to users in such a way to prevent users from being able to remove the apps or desktops from Receiver for Mac. Available through StoreFront or Web Interface.
  • HDX Windows Media Redirection. Offloads video content fetching and rendering for Windows media formats such as MPEG4, WMV and AVI from the XenApp/XenDesktop server while ensuring high quality audio-video playback. Minimum requirement is XenDesktop 7.0 or XenApp 7.5.
  • Improved Diagnostic and Support. In this Receiver for Mac release, Citrix technical support professionals have access to enable, disable, and configure Session Logging and Store Logging to improve troubleshooting and issue resolution.
  • Removal of Mac OS X 10.6 support. Receiver for Mac is supported on Mac OS X 10.7, 10.8, 10.9. Support for Mac OS X 10.6 is removed in the Receiver for Mac 11.9 release and later.
  • Unauthenticated (anonymous). Anonymous authentication is now supported with XenApp 7.6 and XenDesktop 7.6.
  • Improved Desktop Toolbar. Users can now access the Desktop Toolbar in both windowed and full-screen mode. The Home and Windowed buttons have also been removed from the toolbar to improve functionality.
  • Disabled use of SSL v3. To prevent a new attack, such as "POODLE," against the SSLv3 protocol, this version of Receiver for Mac disables its use. See http://support.citrix.com/article/ctx200238.
Important: You must ensure that TLS 1.0 is enabled.

Note: Receiver for Mac 11.9 does not enable smart card use with OS X 10.10 (Yosemite). This is a result of changes to OS X smart card support in Yosemite. Smart card authentication remains functional on other versions of OS X. Citrix and Apple are investigating solutions.
