Certificate Trust Issue on Mac OS Catalina - Citrix Workspace

When trying to run my work VPN via Citrix workspace over catalina on mY iMac, i get the following error when opening the ICA file You have not chosen to trust "VeriSign Class 3 Public Primary Certification Authority - G5", the issuer of the server's security certificate.

This works fine in Mojave which i am running on my MBP.

I've tried opening keystore and trusting the certificate manually, but it makes not difference?

Any idea?

This would be appear to be a Citrix -  compatibility issue and what I have read on the Citrix blogs and forums leads me to believe that Citrix engineers need to upgrade and release new versions of the certificate. I have a similar issue and got a temporary workaround by using Chrome (Google browser) and downloading the Citrix workspace extension for it. (None exists for Safari yet) and my applications were able to run. I had to learn how to juggle between multiple applications as Option + Tab does not work but did it by using different window sizes and desktops and switching as necessary. Hope someone else can be helped as well.


By the way - Citirix did update its app right after Catalina was in general release and new(er) workspace app icon is blue as compared to the prior black one. That is the one you want to download if you are going to try the Chrome route.


Just found this out - Citrix released a new Workspace for Mac - you can download it here: https://www.citrix.com/downloads/workspace-app/mac/workspace-app-for-mac-latest.html


My apps are now working - no more certificate errors
