I'd like to upgrade to Kontakt 7 but the system requirement for the Mac is 10.15. I'm frozen in time (I like it there) and I'm running MacOS 10.14.6 (Mojave's final upgrade). Can I still use Kontakt 7 even though it's a system mismatch? If not, how about Kontakt 6? Is it still for sale? I'm still using the full version of Kontakt 5. Thanks....
