Thank you for your reply!
USB came to me with Cubase 7 Pro, so I guess about 2013 (5 years)
I run eLCC as admin, my user in MacOS is admin but if I run eLCC as super admin (sudo on mac) I get an error that it can’t open Synsopos.app and it doesn’t work.
Maintenance does not fix anything (does the process but then everything remains the same)
In my MacBook Pro where I have not yet updated (still works with high sierra), it works perfectly, so the dongle is ok.
