MacOS 10.15(Catalina) is not supported platform for Adobe InDesign CC2017.
In macOS10.15 Apple enforced strict 64bit rules . Older apps having 32bit components won’t be able to run on Catalina.
InDesign CC 2017 also has few 32bit components hence, it will not run properly on macOS10.15.
Either move back to macOS10.14 OR update Adobe InDesign to latest version that is complete 64bit.Anonymous shared this idea ·
