I am using MacBook Sequoia 15.2.
I have Cubase’s virtual instruments Absolute 4 and Zero Gravity (all others have been converted to and registered with Steinberg Licensing).
It’s definitely present in my My Products software and eLinceers, but it’s missing in Steinberg Licensing. Maybe that’s why you can’t use the instrument on your MacBook because it’s not registered.
Additionally, Apollo Thunderbolt is not recognized by Cubase. The Thunderbolt cable is a Belkin product. Third-party Thunderbolt cables are also not recognized. I would like to know how to recognize Thunderbolt in Cubase, or how to completely delete Cubase from my MacBook.
