We have been advised (usually reliable source) of a change that will come with Catalina. Apparently, all software that is not being sold directly via iTunes will be required to undergo a process called ‘notarization’ … or it won’t continue continue to work under Catalina. It’s believed Apple has decided to ‘relax’ the new restriction for developers until January 2020.
My main machine runs Windoze 10 so it’s not such an issue for me personally. And, the workaround is obvious of course … don’t '‘update’ to Catalina.
But if this post-Catalina landscape turns out to look like this … where are we with WL and plugins on OSX Catalina.
