Which Jqt for macOS Catalina?

[M.Hall]

I'd like to find out the latest J release with a Jqt that works on macOS 10.15 Catalina.  The wiki page System/Platforms says 10.7 or later, but I think that is for core J.  The J app and bin/jconsole work OK. I believe I installed Jqt correctly with "sh updatejqt.sh" .  

Jqt works OK here on Sequoia 15.7, but on Catalina 10.15, when I double-click the Jqt icon, nothing happens. When I run bin/jqt or bin/jtq.command, I see the following:

    $ bin/jqt
    dyld: Library not loaded: /System/Library/Frameworks/UniformTypeIdentifiers.framework/Versions/A/UniformTypeIdentifiers
      Referenced from: /Volumes/ARK2/Languages/J-lang/j9.7/bin/jqt
      Reason: image not found
    zsh: abort      bin/jqt

As near as I can tell, this old macOS release does not have that framework.

(Why such an old system? Because it's my "play around with stuff" system. It's not connected to the net, and let's me install and delete packages and apps without messing up our main system.)

Thanks!

I believe that j903 will work on macOS 10.15. It was the last version to use Qt 5.

You should also try j9.4, which uses Qt 6.2. The subsequent versions use Qt 6.5, which isn't compatible with macOS 10.15.

J9.7 uses Qt 6.10. This Qt version is not supported on macOS Catalina
(dropped since Qt 6.5).

The latest J that should run on Catalina is J9.4.
