IK Multimedia CSR

Single plug-ins (see screenshot).

I’m not a Mac guy, so I probably can’t be of much help to you.

What I do know is that when I last re-installed everything from scratch on my DAW machine, I didn’t install the original version of CSR (32). Is it possible Cubase isn’t “seeing” the folder where the new versions reside? Can you locate the folder where the new versions are installed and make sure Cubase is searching that folder in it’s plug-in paths? Maybe try moving the old CSR files so Cubase doesn’t see them?
