Update From Ventura To Sonoma. (The Things You Need To Do With Your EFI)

As I'm sure all of you came here looking for the things you need to change to get your EFI ready for macOS Sonoma from Ventura.

(IMPORTANT)

First off, if you're installing the most recent one, which would be macOS Sonoma 14.4 from the OpenCore guide and App Store. You need to delete AirportITWLM and replace it with the macOS 14.4 AirportITWLM version as seen below. No, for this step, you don't need to even touch Config.plist since they have the same name, just a different version.

(IMPORTANT)

Second of all, before installation, go into your Config.plist file and go to MISC -> Security -> SecureBootModel. Set it to Disabled, and of course, the "D" must be uppercase as it’s case-sensitive. You don't need to use a specific app to change the configuration; you can use any. I recommend ProperTree or OC Auxiliary Tools.

(IMPORTANT)
Last but not least, this is an issue that might not happen to everyone, but it happened to me. So, I recommend you read this but don't do this step unless you encounter the problem. If you do, follow the steps listed below. (This problem will not break macOS and will not make it non-bootable.) After the Apple logo with the bar is done loading, the screen goes fully black for 5 minutes and then becomes normal. This happens on every boot. The screen isn't black; it's just very dark, so you will need a phone flashlight to see it, but that's a terrible fix.

Here is what you're gonna want to do. You're gonna go into Boot ARGS in Configuration. You're gonna edit it, not delete the text in it. You're gonna write -igfxdbeo next to the text and make sure there is a space. You want it to look something like this: (RandomTextBootup -igfxdbeo). Then you're just gonna reboot, and all problems are solved. Welcome to macOS Sonoma.
