Upgrade to Cubase 11 Pro?

I’m using CUBASE ARTIST 9 and i would like to change for any CUBASE PRO.
My actual configuration is: macbook pro 15 pouces rétina début 2013 with OS X El Capitan
Wich CUBASE PRO can i have with this configuration?

If you purchase Cubase Pro 11 it will allow you to run previous versions as well. So, OS compatibility shouldn’t be an issue. Also, you will get a grace period update to 12 when it is released.
