On two of the Macs, as soon as I fired up the Citrix app, the Java vpn window would show 'error'. Then I remembered that I had done some Java development in the past and installed various jdks from Oracle so I ran: That was on the working Mac.Then I remembered the difference between 'System' Java, Java plugins, and Java development kits.We respect its storied history, and value the contributions of its many readers, but we can no longer support it at the level it deserves.
To fix things for the moment I simply removed the jdk folders.
And then checked that the reported version of Java was 1.6 on each Mac.
Phrases like 'Call my wife' or 'Tell my dad' stopped working.
Siri knew who those people were but proclaimed 'Uh oh, I don't have a phone number for Jane Isa Doe." and beneath, there's a message: "Content Not Available." I debugged this for over an hour and on a hunch, found a workaround that seems to work for nearly everyone who has tried it.
For Safari, enable the Develop Window and use an option in there that works. [crarko adds: I don't have an older system active at the moment to try this.
It's inevitable that older software becomes obsolete, the same way older hardware does.
Recently, I was trying to get a Java applet to run in the same way on 2 i Macs and my Mac Book Air.
The applet is a simple vpn client from Juniper that lets me access a Citrix Desktop from any Mac that I can install the Citrix receiver client on so I can work on 'Company stuff' from a large screen i Mac when I'm sat at home or from my Mac Book when I'm on the road (it works fine over 3/4G).
Simply put, you can have multiple versions of Java in different places.
