Rhino 7 Won't Run On My Macbook

After updating RhinoWIP to the latest version, it no longer will run on my laptop. When I try to open it a banner pops up saying " **You can’t use this version of the application “RhinoWIP” with this version of macOS. You have macOS 10.13.6. The application requires macOS 10.14 or later." I updated my Macbook and it does not give me the option to update any further. Is there a way to resolve this?
Thank you!
