The last time I investigated Cubase 10.x Elements on macOS Catalina, I discovered licensing was restricted to USB key, and soft eLicenser was temporarily not an option until further notice:
However, the latest release notes for eLicenser Control includes (emphasis added):
eLicenser Control Version 22.214.171.12459
Mac/Win SynsoPOS: Fixed macOS 10.15 (Catalina) Soft-eLicenser compatibility issue.
Question: Is it now possible to install Cubase 10.5 Elements on macOS Catalina using Soft-eLicenser for the license?
