Catalina Patcher
So if you do install Big Sur, Catalina, or any recent version of macOS on an unsupported Mac don't expect it to run smoothly. The patch will enable you to install Catalina on an older Mac. Install macOS normally onto the desired volume. When the install completes, reboot back onto the installer drive. This time, open the 'macOS Post Install' application. In the application, select the Mac model you are using. The optimal patches will be selected for you based on the model you select.
