Latest Mac OS for Cubase AI8 and UR22mkII

My iMac (at least 10 years old) is dying, thinking about buying a new one. I have Cubase AI8 (the latest version) and a Steinberg UR22 mkII. What is the the latest Mac OS that will work with this combination?

Hi and welcome,

The latest officially supported system for Cubase 8 generation was macOS 10.11.

Thank you for replying!
