Unsupported mac

I need some help, I have a 2012 macbook pro, I used ocpl to install sonoma in it qnd also install the graphics and wi-fi patches. After a few days the mac started to misbehave that i could hardly access my applications so i prepared another installer in another mac. Whenever i try to install the installer i have prepared in my 2012 macbook pro 2012 it gets stuck on progress bar at the late stages of the installation. What can i do?
