Desktop stuck in black screen after updating to 18.9

[Pedro Ricardo Garcia de Oliveira]

After logging in Citrix and selecting the application for the Remote Desktop, it opens a black window and it stays this way forever. The window is responsive in the way that it can be resized and the options are available, its even possible to enter the preferences. However the screen keeps black.

I'm seeing the same issue with some of my users. Seems to be related to the workspace app, osx, and retina displays. The windows and mobile workspace apps work fine.

I switched to a Windows 10 VM running on VMWare Fusion 11 on Mojave to try and get around this black screen issue, which I am also seeing. But the Citrix Workspace app crashes the VM.

 

So if the devs can fix this... that would be great!

 

(update 22/Oct if you shutdown the fusion VM guest and turn 3D Acceleration off you can then run Citrix Workspace inside your VM fine)

Same issue here running Mac OS 10.14 on iMac Retina 5K.  Citrix was working fine until 18.9.0 update last week.  Now get the black screen of death! 

 

Citrix Please FIX THIS!  ASAP!

[Kenny De Man]

Anyone found a solution for this already? We are facing the same issue... Connectivity in the back-end seems fine, it's just the screen in the Citrix Viewer that stays black... 
Haven't found a knowledge article yet, anyone had more luck?

Same problem here for example with Mac OS 10.13.6 on MacBook Pro 13 (2017) and other iMacs. Issue occurs since Update from Receiver to Workspace 18.9.0. Has anyone already open a Support-Ticket and have more Information?

We are running XenApp 6.5 on Server 2008 R2.

[Alexander Koehler]

Did all of you having this problem using XenApp 6.5? I´ve opened a Citrix Support Case and get the answer, that 6.5 is no longer supported by Workspace App (yes, i know that XA 6.5 is general EOL) and my Users should use older Citrix Receiver Versions.

I'm having the same problem using Mojave with Citrix Workspace 18.9. It was working fine until the 18.9 update installed yesterday. Every time I press the enter key in one of my applications, it hangs up for several minutes. this is EACH time I press enter....this is really unacceptable!

[Alexander Koehler]

I can confirm the answer from Citrix. We´ve now tested a macbook and the new Workspace App with our Development Farm XenApp 7.15 and it works. No Black Screen. It only happens when connecting to our XA 6.5 Farm.

I had a similar problem with Mac OS Mojave after being upgraded to the latest workspace app. The only solution I found was to delete the workspace app altogether and to reinstall Citrix Receiver v 12.9.1. It now works fine using this. It is available here: https://www.citrix.com/downloads/citrix-receiver/mac/receiver-for-mac-latest.html

Same here. Mac + Citrix Workspace == Black screen

We had a user getting a white screen on MacOS.  Older imac model and they had an external monitor plugged in for a second screen (may or may not contribute to the glitch)

 

Tried reinstalling, deleting preference files and cache files.  Basically everything in the ~/Library folder with filename that included citrix and it did not help.

 

This command got them connected.  Just had to make sure that all citrix processes were stopped first before setting this preference on the command line.  Quitting the menu bar icon and any viewer sessions that were running seemed to be required.
