I have an older Mac and Kontakt 4. I've since upgraded my OS to the highest level my Mac can handle which is 10.11. That OS is too high for Kontakt 4 and Kontakt 6 (the latest) needs 10.12 which my Mac can't go to.

What alternatives bundles are there for Kontakt 6 where it would have pianos, organs, brass and strings? Or - is there a place to buy Kontakt 5?
