“Images cannot be initialised” What do I do?

Full warning translated: “Images cannot be initialised. This usually happens when running in an unsupported virtual machine environment or when running on an unsupported Mac.”

I have gotten Garageband from another Reddit post with all comments saying that it worked perfectly fine so I wanted to try it out on my iMac mid 2011 with Monterey. (They also used OCLP)

Before the warning comes up, I’m able to play a note, so it should work.

What is going on and how can I fix this?
