Question: Accidentally upgraded to Catalina and now photoshop (and final cut) have stopped working, great! Any idea what versions of photoshop work on Catalina? According to Adobe, Photoshop 20.0.7 and 21.0 work with Catalina, but there are known compatibility issues: https://helpx.adobe.com/photoshop/kb/photoshop-and-macos-catalina.html
