I tried uninstalling Citrix Workspace (making sure there were no files left in the Library folder) and re-installing the latest version compatible with my version of mac: Citrix workspace version 19.6.0.32 (1906). However the problem remains. Citrix Receiver / Desktop Viewer stuck on Connecting due to HDX RealTime Optimization Pack? Recently had an issue where I could not connect to a customer's Citrix environment and my Citrix Receiver / Desktop Viewer was just hanging there on Connecting and then timing out. The Citrix Workspace app allows for secure, unified access to all of your SaaS apps, web apps, virtual apps, files, and desktops. If your company uses Citrix, simply login with your company credentials to access all of the resources you need to be productive from anywhere.
- Login to your Citrix Desktop.
- Next you will move your mouse to the top of the screen and click on the black rectangle to show the drop down menu.
- Click on Window button to shrink the Citrix Desktop Viewer Window so you can adjust the size.
- Move your mouse to the right side until the horizontal arrow appears and then drag the Citrix Desktop Viewer window onto your other screen or screens.
- After the Citrix Desktop Viewer window appears on all your screens, click the drop down menu and select Full Screen.
- After clicking the full screen button, your desktop should appear across all the monitors.

This post explains how to launch Desktops and Applications in Windowed Mode using specific resolutions or a percentage of the screen.
By default when we launch applications and desktops they launch seamlessly as if running on the local endpoint. If applications and/or desktops behave in a way were seamless does not suit, you may want to consider launching those problematic resources in Windowed Mode instead.
Launching in Windowed Mode is easy and can be set up per resource. You can either define a static resolution or define a percentage of the screen.

On your StoreFront server(s), navigate to C:inetpubwwwrootCitrixCitrixStoreApp_Data.
Note: Your path will be different depending on your Store name.
Now launch default.ica in a text editor.

To set a specific resolution underneath Application= type in brackets [] the name of your application as displayed in Citrix Studio. Underneath type the [Application] name type:
TWIMode=Off
DesiredHRES=
DesiredVRES=
The resolution is up to you.
Save the default.ica file. The next time youu launch a resource it will display as below in Windowed Mode:
Citrix Workspace Desktop Viewer Windows 10
To set the Windowed Mode as a percent of the screen, replace DesiredHRES= and DesiredVRES=with ScreenPercent=. This works well especially for published desktops.
