I am using OCLP version 1.3.0 to install Sonoma 14.3.1 on a Macbook pro 13 early 2015 running Monterey 12.6.7. The problem I am facing is that after selecting boot from EFI option and then the install Sonoma option, an odd looking progress bar without no apple logo appears and it always never moves pass 1/5. The computer itself is fine and usable since installer won't even load. But still, I just don't get what exactly is happening and I can't find any information about not even being able to load the installer.
