Mac Resolume Arena Installation Help -- 2

I need Resolume Arena up and running on my Mac as soon as possible. I have not bought a licence yet, so the first step will be your guidance on which licence tier suits typical live-visual work and how to complete the purchase through Resolume’s official channel. Once the licence is secured, I expect you to handle—or walk me through—every step of the installation, activation, and any macOS security permissions that might appear along the way.

Please confirm compatibility with my current macOS version before we start and outline any extra components (drivers, codecs, etc.) that must be installed. When we finish, Resolume should open without warnings and be ready to load compositions, map outputs and trigger visuals during a show.
