Jing will be retired soon, and you can learn more about this here
When attempting to open Jing on Mac, Jing needs to be updated is displayed.
This issue occurs when the macOS is upgraded to macOS Catalina. Jing will only stop working when upgrading to macOS 10.15 Catalina. With this new release, any 32-bit applications will no longer be supported, including Jing. To continue using Jing, only upgrade to macOS 10.14.6 Mojave.
We are currently working on a free solution that will be compatible with Catalina.
