Resolved Issues

Fixed issue with USB Devices menu with macOS client running on Catalina or Mojave


Fixed an issue with the USB driver which prevented USB devices from being connected to the remote desktop.

Fixed issue with client connecting to Cloud Access Connector (CAS Manager) that was configured for external access


Fixed an issue that prevented the client from connecting to a Cloud Access Connector server that is configured for external access.

PCoIP client can now be launched via URL on any browser on macOS


Fixed an issue where the configuration of the macOS client prevented launching the client via a URL on the Chrome or Firefox browsers.

Fixed mouse coordinates for specific display topologies


There were a number of display topologies where the mouse coordinates were not accurately calculated. This resulted in the mouse pointer being drawn at the wrong locations. Some of these conditions occurred only when relative mouse was enabled.

Known Issues

macOS client may only minimize one display on OS X 10.11


If you launch the PCoIP Software Client in OS X 10.11 and you have not clicked anywhere within the display before using the minimize hot key (Ctrl+Alt+M), the display that has not been used will not be minimized. This does not occur in macOS 10.12 (Sierra) or 10.13 (High Sierra).


Click with the mouse on both displays of the client any time before pressing Ctrl+Alt+M, and both displays will be minimized.

USB Flash drives fail to bridge at times


USB Devices dialog (from Connection > USB Devices menu) may freeze for a few seconds after clicking the connect or disconnect button associated with a USB Flash drive. When this happens after clicking connect, the device fails to connect. When this happens after clicking disconnect, the device is successfully disconnected.


Retry by clicking connect again on the USB Devices dialog.

USB DVD drive unavailable on client USB Devices dialog in macOS


If a DVD drive is connected to a client via a USB hub and the device is bridged quickly after connecting to a host, or if the device is unplugged from the hub and re-plugged, its status will be Unavailable and users will not be able to bridge the device.


Unplug and re-plug the USB hub.

macOS French localization disables View > Show Fullscreen toolbar menu


When the client locale is set to French in macOS, the View > Show Fullscreen/Leave Fullscreen dropdown menus may not be accessible.


Enter the Ctrl-Alt-Enter key sequence to toggle between fullscreen and windowed modes.

Datalogic barcode scanner cannot be redirected when bridged in macOS


The Datalogic Quickscan QS6500 barcode scanner does not work when the device is bridged.


Do not bridge the device. The device works as expected with the remote host when it is not bridged.

Wacom Intuos Pro and Intuos 5 tablets cannot be bridged


These tablets work as a pointing device when a session is not active, and when the tablet is not bridged while a session is active. When the tablet is bridged, the device manager application running on the remote host displays a warning icon next to the tablet and the tablet does not work.

Intuos PTH-660 and PTH-860 tablets are not impacted by this issue.


Avoid bridging Intuos Pro and Intuos 5 tablets.

USB keyboards do not work in bridged mode


Keyboards do not work when bridged. This affects both Windows and macOS PCoIP Software Client.


Do not bridge the keyboard. Keyboards function correctly when locally terminated.

Client window size is not remembered when crossing multiple monitors


When stretching the client window across multiple monitors, client window size is not remembered for session reconnects.

Zooming in macOS while connected to hard host throws local and remote mouse out of sync


Using the zoom button on PCoIP Software Client for Mac will result in a desynchronization of mouse pointers when connected to hard hosts. Teradici recommends not using the zoom button on macOS while in a PCoIP Software Client session connecting to hard hosts.

Mouse out of sync due to scaling in dual high-resolution displays


Connecting a PCoIP Software Client session with dual high-resolution displays in full-screen mode (2560x1600 for example) to a hard host that does not support high-resolution displays may result in unexpected behavior. For example, one or both displays may be scaled to single link DVI resolutions without the client also scaling, resulting in unsynchronized mouse movement.


Set client desktop to single link DVI resolutions. Alternatively, upgrade host GPU to support dual-link resolutions (Tera2 hosts only)

Audio input in PCoIP Software Client with PCoIP Remote Workstation Card does not work


When in session with a PCoIP Remote Workstation Card, PCoIP Software Client supports audio out from the host, but not audio into the host.
