Sadly enough, Soxy is now end-of-life and won’t be upgraded or updated any further.
Soxy is a 32-bit application; it won’t run on macOS Catalina.
The last few years, the cost of building an update to Soxy for every update to Adobe Create Cloud or QuarkXPress had already ballooned far above any revenue it generated, and the end of 32-bit support in macOS Catalina was the final straw that broke the camel’s back.
We have no plans to update Soxy for InDesign CC 2020, QuarkXPress 2019, and Soxy won’t ever work on macOS Catalina.
