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)

PCoIP Client will crash on illegal instruction on M1 Mac with PCoIP Ultra GPU Offload


If PCoIP Ultra GPU Offload or Auto Offload is enabled on the PCoIP Agent, the PCoIP Client running on an M1 Mac will crash due to an illegal instruction that Rosetta 2 cannot translate for the M1 processor.


To disable PCoIP Ultra on the PCoIP Client for macOS, add the following line to ~/.pcoip.rc:

pcoip.enable_h264 = 0

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.
