Updating 2012 MacBook Pro to macOS Ventura
The decision to update the MacBook Pro 2012 model to macOS Ventura is prompted by Apple's discontinuation of security updates, along with other app providers ceasing updates. This update aims to maintain the device's security and ensure it stays current.
What began as a straightforward task turned into a 5-day endeavor. Despite not being covered in YouTube videos, while troubleshooting various errors, I realized this was an entirely different challenge.
Whenever a new error pops up, the solution involves installing macOS Catalina, updating it to the latest version, and then following the steps again.
The issues started with an "opencore legacy patcher chunklist validation failed" error. This was followed by a " installation cannot proceed because the installer is damaged". Additionally, an "an error occurred preparing the software update" message appeared.
I'm in the process of listing the errors encountered in the steps. You can find the full details of steps in the links below.
