Install Catalina 10.15 on unsupported MacBook Pro

I have previously run Mojave 10.14 on an unsupported MacBook Pro thanks to Mojave Patcher. Now Catalina (10.15) is out, and so is Catalina Patcher (1.1.7).

The only story to tell is a short story of success:

  1. I downloaded Catalina Patcher
  2. I created a bootable SD-card
    • you can obviously use a USB drive instead
    • you can use a previously downloaded Install Catalina-app, or Catalina Patcher will help you to dowload
  3. I restarted the computer, held down Alt, and started the Catalina Installer
  4. There was no upgrade option, so I just picked “Install”.
  5. It took about an hour, a few restarts but I needed to do nothing
  6. All well! My user, all data, all configuration, all programs perfectly in place.

No need to patch manually, to choose hardware, or anything. All just smooth.
