Before You Begin

You will need a Macbook or Mojave Hackintosh, to begin with. If you don’t have one, use your friend’s MacBook or Hackintosh system. We need that to create the macOS Catalina USB installer.

And please back up your important files from your Hackintosh system. If possible, clone your existing Hackintosh or use a different drive, preferably external to install macOS Catalina as we did in the previous post. Better safe than sorry!
