Run Cubase 10 on Cubase 10.5 License

I had purchased Cubase 10 but it was automatically upgraded to Cubase 10.5. My OS is Mac Hi Sierra. I believe Cubase 10.5 will not run on it so i want to continue using Cubase 10.
Is it possible to do so with Cubase 10.5 license

Hi and welcome,

First, you could try to start Cubase 10.5 on Hi Sierra. Most probably it will work.

And to answer your question… Yes, you can start Cubase 10 with Cubase 10.5 license.
