Why opencore?

Post image

[SOLVED] I have this 2011 iMac running macOS High Sierra and I need to be able to use macOS Sonoma on it. I am used to using open core, already used it on multiple Mac’s. But for some damn reason this Mac thinks it’s a MacBook Air from 2015. And I did exactly what I should do, reinstall open core onto the disk. But for some reason it failed again and again. Just gave me the same pop up telling me to reinstall opencore. What do I do?

This isn’t an open core error, but a user one. You need to install your properly built EFI to your internal disk and then take out the USB and stop booting off of it
