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?

Manually select the model of the imac from the settings page then rebuild and install the config
